Title: Technical advice -antennas and satellite dishes
Post by: JeffH on January 18, 2014, 03:06:24 PM
If you have any technical questions about TV reception;
•Antennas
•Cabling and splitters
•Amplifiers (often called "boosters")
•Satellite TV
and such like.

Please feel free to ask me. I almost manage to make a living doing installation and repairs to this type of equipment -sometimes I actually come out ahead on the finances.

To get started here are a couple of links that could be of interest;
•The restack of digital television services (http://www.communications.gov.au/television/achieving_the_digital_dividend_-_restack) Hidden in this page is the reason why many people, who have recently upgraded an aerial system for digital reception may have to upgrade again very shortly!
•Viewer Access Satellite Television (https://www.myvast.com.au/) This is all about the free to air, digital, satellite TV. Note -this initially came up in my browser as an untrusted site. It is an Australian Government sponsored site and is actually safe.

Cheers,
Jeff

If you mean reset, hold Select and Back on the front of the box. If you mean hack to steal premium channels, you can't.

Thank you Jeff for the kind offer to answer questions.

I live in a hole at 50m (200m hills to the east, 300m north, 250m south, 600+m west) so there is no direct line of sight to any of the transmission towers hence we need an amplifier to get a decent reception.  The old one we had worked great (an Alcad AM-126 Laceys.tv) but it's kicked the bucket. I've been going to get one of the Hills Q-Amp Digitial amps (specificly designed only to amp the digital range).

Have you had any experience with these? Are they OK?

Thanks heaps.

Post note: They're masthead amps ..... but you probably knew that eh!

Depends on several factors.. mostly where its pointed and what's plugged into it. There are a huge number of satellites up there, and you can pick up any that are visible from your location. What they carry, and whether its encrypted, is another matter. Generally speaking though, anything coming into the country, internal network traffic, and public access stuff is unencrypted, so there's a lot of fun to be had.

Not as much fun as a few years ago before Foxtel changed their encryption though.. you used to be able to get all their channels back then if you knew how. ;)

Oh, and speaking of fun with dishes...

I knew a guy years ago who lived in the Yarra Valley. He and a mate on Mt Dandenong, both amateurs, bought a couple of government surplus 30m dishes, and planted them in their back yards. Now there's not a lot of call for dishes that size... so for a bit of a challenge, they used them to talk to each other on the 2m VHF amateur band. Not a big deal I hear you say, since you could cover that short distance with a handheld and a wet bit of string. But they did it.... via the moon! 2m moonbounce is not something you come across every day... ;)

The Hills Q amp is one of the better ones available. There is a new, upgraded model now available which promises better performance but I haven't tested one of those yet.
Digital reception can operate well with much less signal level than analogue required for a good (snow free) picture. But the signal "quality" is all important. Any signal processing, such as an amplifier, will reduce the quality. As a rule of thumb the lower, the "noise figure" an amplifier has, the better the quality of the amplified signal.
The Hills LNDA amplifier is lower gain than the Q amp but has a better noise figure.
From comparative testing the best noise figure of any commonly available amplifier is the Kingray MDA series. Has similar gain to the Hills LNDA.
With these lower gain amplifiers a distribution amplifier may also be required to maintain adequate signal level for multiple TV outlets.
Some of the European amplifiers distributed by Laceys also offer very good performance. Many of the Chinese amplifiers are inferior but they are improving (same with antennas and Chinese antennas are mostly now comparable with Australian made units).

A large satellite dish [say 1.8m+] is probably a left over from the past when satellite transmissions were much lower frequency and power than newer ones. May be overkill for what they are receiving now but, why change it if it works. Or they may be wanting a particular signal from a satellite well toward the horizon. Some satellite internet providers use a satellite way out over the Indian Ocean and need a relatively large dish (which is pointed west at a low angle). Two way satellite internet (where your computer is sending signal back to the satellite as well as receiving) requires a reasonably large dish -we are talking very small signal levels here. A satellite internet connection that uses satellite for download and phone for upload only requires a small dish comparable to pay TV dish.
Is it a solid surface or mesh surface dish?

As to what the people down the road are receiving? Only way to find out is to ask them; could be any of hundreds of transmissions. Take your pick from here Asia & Pacific (http://www.lyngsat.com/asia.html). The main ones servicing Australia are in the range of 169ºE to 152ºE.
Many transmissions are "scrambled" and require a paid subscription to decode. Many transmissions are foreign languages and not of great interest to English only speakers.

PS. If you want to receive ABC and SBS TV via satellite then you don't need an expensive "VAST" receiver with a registered smartcard.
They use Optus D1 satellite for downlinks to their transmitter sites around the country and these signals are not encrypted. Optus D1 at 160.0°E (http://www.lyngsat.com/Optus-D1.html)
Any generic satellite receiver is suitable -as long as you are happy to forgo high definition- and these can be picked up for next to nothing on eBay. Dish size will depend on your location but an ex-Pay TV dish from your area can usually be obtained free (you may have to recover it yourself) by asking around.

¿que?
Are you sure? A 30m dish is about the same surface area as a suburban block of land or six Olympic swimming pool lengths across! Here are some 22m dishes near Narrabri.
(http://www.australian-coins.net/gallery/albums/userpics/10055/22m_dishes.jpg)
I know of some 3m amateur dishes and 6m is about as big as they get. I have a 2.1m dish here and that is fairly large for a backyard. It was installed originally for the Remote Area Broadcasting Service and I replaced it with an 85cm dish a few years ago for the newer service. Customer didn't want the old dish so I thought it would be worth grabbing.

An ex-Navy man near here has a 30 foot (about 10m) dish he brought with him when he left the service. Bet his kit bag was full when he walked out the gate!
He uses it to receive the VAST free to air digital service. It is rotatable -he has fitted an HQ Holden disk brake to stop it moving in the wind.
A 65cm dish would suffice.

Try it first without a distribution amp. If all fine then end of story.
Quality of distribution amp. is not critical (head amp has biggest effect on overall quality). And, don't be sucked into buying a distribution amp. with very high gain -10db to 18db is adequate for a household installation.
Check with me first before buying one and I can point you in the right direction.

And virtually every digital TV and STB has some sort of signal indicator (often "strength" and "quality") built into the menu system. This is handy for checking that anything you are doing is making improvements -good for fine tuning antenna aim too.

now that would be COOL - plenty of shade for the car - unless it got fried before it cooled down
I went to the dish at Parkes on the way down to Canberra when we moved
and then  up to Stomlo observatories and then the Tidbinbilla dishes when we got here
I think it is all fab

I presume so. That back building wasn't there 25 years ago, and I remember it being a lot further away. I guess things change... there's no sign of the traffic light he used to have out the front... which seems to have been replaced by a tree. Used to be great fun... a car would slow down... stop... back door open, kid run out, push the button... then hightail it back to the car when the lights changed! Many giggles from everyone in the house as the car then sped away.

Yes, could be a dish -fiddled with the contrast on a screen grab and looks like it throws a shadow.
If scale on the map is accurate that makes it about 5m diameter.
The total width of the house block scales at around 30m.

Thinking of buying an electronic device from Aldi -the prices are very attractive?
May I suggest you do a little research on the net first; plenty of reviews out there.

If you still want to proceed with your purchase carefully check the warranty conditions and ask if the item can be returned to the store when if an issue arises. If the answer is "yes" ask for that in writing because you could be setting a precedent. Consumer guarantees {Who to claim a remedy from} (http://www.accc.gov.au/consumers/consumer-rights-guarantees/consumer-guarantees#who-to-claim-a-remedy-from) This does not necessarily apply as far as Aldi is concerned.

tI is also worth checking the level of support offered. Don't bother going to Aldi website -nothig there about electronic products they sell. Instead try TEMPO Australia (http://www.tempoaustralia.com.au/tempo/home) and click on the brand name of your item of interest.
Did you find your item? Did you notice the "© 2014 ALDI" somewhere on the page? Maybe you should download the owner's handbook to familiarise yourself with your forthcoming pride and joy -good luck finding it! Also, just for the heck of it enquire about buying a replacement remote control.

To my knowledge Aldi has never manufactured electronic products and Aldi owns the brand names it sells.
So where are they made? Clue; Google "middle Kingdom" and the answer is not "Egypt".

Cheers,
Jeff

Why not indeed.
But try returning an appliance with a 12 month warranty, to the store it was purchased from, 3 months and 1 day after the purchase. You won't be happy with what you get told.

And, I didn't mean to suggest all Chinese items are rubbish. Far from it in some cases -they are probably repeating the Japanese learning curve ; but faster! And in other cases.....(don't ask).

PS. My advice is applicable for nearly any purchase. The better informed you make yourself before forking out your hard earned; the happier you are likely to be with the resultant purchase.

I just gave a example of returning something to Aldi, which went fine.

Some retailers (or their staff) may be ignorant of their legal responsibilities (or may try to avoid their responsibilities) but the rules still apply to them.

Your original post came across as 'anti Aldi' to me, but I think it was intended more as a general 'buyer beware'?

"F11" is the button to capture a snap with many of these. But it could be another of the F buttons depending on the software. Have a search through the menu buttons of the top of the screen to suss out options available.
With my computer I need to hit "F Lock" button first for "PrtScn" to work. These buttons each have two functions and, which one happens depends on whether F lock is on or off.

Have you tried to use the new device with the software for the old device? That may work too.

These things are a hardware/software combination. As we discovered with the KB's, not every combination works. Far from it.

I would search for alternative software for it. There are likely different versions apart from what came on the disc. Google it, chances are there is a solution in some forum.

And if all else fails, screenshots, though crude, will give you something at least.

TV transmission frequencies are being changed. Now that analogue TV has been turned off, there are many spare frequencies.
Digital, unlike analogue doesn't require separation between frequencies. So, digital transmissions are being "stacked" (changed to blocks of adjacent channels) in many areas. Unless your TV set has auto detection for new transmissions you will need to retune when the change happens.

To check requirements for your location go here Australia is retuning (http://retune.digitalready.gov.au/) and enter your postcode in the search box.
In some areas an antenna upgrade may be required but, in most cases, existing system should suffice. My advice is to wait and see.

The large block of frequencies thus freed up can be used for other purposes -most likely auctioned off to mobile phone providers for a lot of money.

Geeks can get further information here...Restack of digital TV services  (http://www.acma.gov.au/Industry/Spectrum/Digital-Dividend-700MHz-and-25Gz-Auction/Restack/restack-of-digital-tv-services-spectrum-for-broadcasters-acma)

Which of course was the entire point almost from day one. Does anyone even remember the original guff about super-high quality we were supposed to get from digital? Seemed no sooner had they baited that hook, everyone started talking about twenty bazillion channels (with proportionately more advertising revenue of course) serving up the exact same crap instead.

Yet another con courtesy of our glorious leaders. Bah.

Ah, I'm glad you asked, because there are very good reasons for just about everything to do with film and TV.

Firstly, Hollywood turns out about 450 feature films a year, total. Including all the D-grade crap. That's about 600 hours. The rest of the world combined probably comes up with the same again.

Now that channels are up 24/7, each one has 8,760 hours of airtime to fill. If we take movie channels for the moment, since that's where the HD is, you can see that each film would have to be shown ten times, even if every new movie was screened, which they aren't. That wouldn't work. Look at Foxtel's programming, and you can see they get to about 8 repeats over a month, using their 2-hour offsets.

Advertising of course fills some time, but with movies you can't really interrupt the show. Cue the back catalogue. People have short memories, and will watch stuff from ten years ago even if they've already seen it a dozen times. Especially kids, who have been known to literally wear out video tapes.

Things get better for the programmers with TV shows. Firstly production is cheaper. MUCH cheaper. And you can skip the expensive HD airspace. For starters you can get away with 24 minutes of ads per hour. Then you can pad with say 2-3 min each of "Previously on...", "Next Episode..." and of course the fancy CGI title sequence which airs every episode. So now our hour costs 30 minutes of production. Cue the promo spots. By the time that 30-minute hour of production dollars airs, its had maybe 120 minutes of teasers, which don't count as ads. And then sometimes you can get away with a "Making of..." or similar show about the show. My Bull***t Drools (Sorry, MKR) excels at this, for example.

Repeats give them extra bites at the cherry, almost for free. Even if the programming source is external, and therefore must be paid, prices are a tiny fraction of first-run programmes. If its an in-house production, then it really is money for nothing.

At the end of the day, its all about maximising eyeballs (and therefore revenue) for minimum cost. There are lots and lots of dirty tricks they can use, and they're not at all shy about using them all constantly.

And the dirtiest trick of all is the Pay-TV con. The promise was more and better programming, ad-free, because subscriptions paid for the content. That lasted about five minutes into the rollout. What we have now is exactly the same content, with even more ads and promos, and a hefty monthly bill for the priviledge.

Is it any wonder so many people are investing in media servers loaded up with ad-free content of their choosing, and never turn the telly on except for news?

Post by: JeffH on March 21, 2014, 12:46:35 PM
You didn't really expect multiple channels full of new, exciting programmes did you Nancy!

There is a certain lack of logic in the use of the channels. Take the ABC for example;
•ABC 1 (channel 2, standard definition). ABC's premier channel. A lot of the newest content is made in high definition but only broadcast in standard definition.
•ABC 1 (channel 21, standard definition). Exactly the same as above!
•ABC 2 (channel 22, standard definition).
•ABC 3 (channel 23, standard definition).
•ABC 4 (channel 24, high definition). High definition -great advantage for the studio shots of talking heads, NOT! And the newsclips are invariably standard definition and often rather poor video quality.
For a while there ABC 1 on channel 21 was high definition. Then, about the time HD set top boxes became readily available and HD TV sets were getting good penetration into the market they changed that to an exact duplicate of channel 2 and introduced "ABC news 24" on the HD channel.
They must have a reason for doing what they did but I cannot fathom it.

Just saw Fulvio's rant. Explains the reason why a lot of people (at least around here) are cancelling their Pay TV subscriptions. Rationale is "why pay extra to watch old crap and repeats when I could watch it for free on the new digital channels?".

I have a scaled down version of Pay TV for minimal $$$'s, and get  more channels (Sport) added for Tennis that starts in late May (French Open) and goes till late Aug / Early Sept (US Open). At least I get to see some HD Tennis.

After that, I knock it back to where it's at now. My son pays for it, so I'm not real sure of the $$$'s involved.

Not me. I don't watch any. Well, apart from the odd bit of the news when something is on the go, like the Malaysia flight.

But I have a massive media collection, which I'll maybe get around to one day, if I live that long.

Oh, and I used to be in the industry... watched a LOT of content every day back then... I kinda wish I'd spent the time noodling instead. ;)

If you are outback or in a "black spot" signal area you may be interested in this I have listed. Digital Free to Air (VAST) satellite receiver. (http://www.ebay.com.au/itm/281294973921?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649)

WTF???? Registration? Permits? Sounds as dodgy as charging for TV licences... :dodgy:

That's a Government sponsored service for you. Access to ABC and SBS satellite transmissions is unrestricted, Australia wide; except for the little matter of registering your details and having your smartcard activated! Bah! Humbug! I say.

Of course, if you know what you are doing, you can point the dish at a different satellite and get all the ABC and SBS transmissions, without a smartcard and just about any receiver (at about ¼ the price of the authorised receiver) will suffice. That only gives SD picture and, if you want HD (why bother?, I ask) then you might have to splurge up to ½ the price of the authorised receiver.

Maybe a few bureaucrats (and a couple of politicians too) should be hung, "pour encourager les autres".

Not to be contrary, but remove the words "Maybe" "few" and "couple" and I'll agree enthusiastically with you. :diablo:

What does this all mean? Australia is retuning (http://retune.digitalready.gov.au/)
Analogue TV requires channels not be adjacent frequencies otherwise they will interfere with each other. Digital TV works happily with channels on adjacent frequencies and we now have digital TV country wide.

So, why bother? By "stacking" digital transmissions on adjacent frequencies a large number of other, contiguous frequencies are cleared and available for other uses. "What other uses?", I hear you ask. Check out this article to find out...Telcos testing new band  (http://smh.digitaleditions.com.au/OLIVE/ODE/SMH_DAILY/LandingPage/LandingPage.aspx?href=U01ILzIwMTQvMDgvMDQ.&pageno=Njk.&entity=QXIwNjkwMg..&view=ZW50aXR5).
If you prefer a simple, single word answer to the question, it is "MONEY". Mobile coverage is being extended into what was previously part of the TV spectrum.

Altech UEC DSD4121 VAST satellite Free to Air satellite box failures. What a mouthful of acronyms!

If you have satellite TV from the otback/black spot service and your DSD4121 (not DSD4121RV, which has a plug pack power supply) dies then;
•If it is still under warranty then claim warranty but, if you can repair yourself it will be cheaper than posting back to Lane Cove to be repaired. Read on...
•Common failure is one of two marginally rated components on the power supply circuit board. Symptom -box completely "dead"; no lights or display on front panel.
•Cost of replacement, higher rated, components is less than 20¢ and repair takes about 20 minutes.

But, you must know what you are doing. There are potentially quite high voltages lurking on a faulty board. Even several hours after power has been disconnected. OK, I've covered my arse -if you (or a friend) can handle a soldering iron then email me and I will send instructions.

Reconditioned power boards are available, on the net from several places. -cheapest price I could find is $55 + $11 postage.
If you would prefer just to get a replacement board then I will supply one for $35, posted -conditional on you posting your old, faulty board back to me.

Cheers,
Jeff

Have you bought one of these? Never Pay For Cable Or Subscriptions Again? This Device Allows You To Watch Your Favorite Shows Without Monthly Fees! (http://thefoxinsider.com/page1/topgadgets/au/tfi_au1_tvf_gg/?c=478&key=2195e4907102999adb341c0249a06d4d&t=94e655045539d2d41749b84aac7c80de&creative=D)
If so, commiserations. You could have spent that money on a decent bottle of wine and had much better value.

If you are considering purchasing one of these amazing devices a word of advice......DON'T.

Their adverts. are popping up on the Bureau of Meteorology weather forecast page (and, no doubt, plenty of other places).
