Hi

My parents in law have got (I think) an 80 cm dish pointing at the Optus D2 satellite (was B3 befor it was replaced)  They want to pretty much pick up ERT World only.

The question is, what will they need to also get the D1 satellite for freeview.

Is this something that needs a second dish, or is this where dual lnb come in?

And secondly if it does take a dual lnb, can you add one of these yourself or does it take a new complete dish, and I take it if there is a single lnb now, there is a requirement to run a second cable from the second (new) lnb to the STB?

I don't know if I'm gone way off base here, but you can prob tell that I don't know a huge amount af what I'm talking about (and only just enough to be dangerous).

Thanks in advance.

What you will need to get is a Dual LNB Bracket for D1 & D2 something like this plus you will need to get a second LNB assuming that the first LNB will go into the bracket, if not, you may need two LNBs, anything will do as long as it's not a Univeral LNB.  Probably also worth getting a LNB that has the same LO frequency as your current LNB ie 11300 or 10750 and then you will need to get a 22Khz Switch to switch the cable between the two LNBs, something like this will do the trick.  Perhaps a small waterproof box to hold the 22khz switch in up on the pole with the dish would be a good idea as well.

Then what you will need is two very short lengths (under 1 meter?) of Dual Shielded Coax with F Type connectos to connect from the 22KHZ switch to the two LNB's.  The current cable connecting into the single LNB will connect to the input of the 22khz switch.

You may need to realign the dish to get both LNB's working correctly, this can take some time, I also recommend taking the TV & STB up onto the roof so you can tune everything in.

That's pretty much it, as long as the dish is big enough then you should be fine.

Lastly you should make sure you water proof everything, as when water gets into a F Connector things can go wrong, don't want to have to keep on getting up on the roof again...

Hope that helps

Cheers that did help.

Ex;plained some of the "things" and let me know that it's probably not something I'd attempt.  But at least I can now ask my father in laws installer for the same thing and be pretty much sure that if he turns around and says you need a new box/dish that i can tell him go jump.

Thatnks.

If he lived in Wellington I could give you a hand, I am no installer but do it is pretty easy... No worries if you have an installer since they will have a good Sat finder and not need to take the TV & STB up on the roof :)

Thanks for the offer, we're in Lower Hutt, but I think we'll still go through the installer, as I understand my parents in law want to get a prime feed as well, so will need a uhf aerial.  So may get all of that done at once.
