I just got one of those old 1 meter primestar dishes and want to get started into the wonderful world of FTA. 
I do have a few immediate questions however.
First, the dish itself weighs a ton due to that enormous mounting bracket on the back of it. Is there a different type of bracket that I can fit onto this thing that would make it a little more light weight?
Also, with that mounting bracket on the back, it wants what looks like a 3 inch diameter pole to mount to, I don't have a 3 inch pole to put it on, nor do I want to go find one.
Is there any way that I can adapt this bracket to fit onto a 1 5/8" pole? (standard size for 'normal' DBS dishes I believe). I would also like to eventually get a motor for this bad boy, and as such, would also require the dish to be either lighter in weight and mountable on a smaller pole, or I would need a super powered motor to lug this thing's big butt across the sky.
Another question I have is regarding the LNBF that is on the dish. I do plan to replace the LNB at some point, but as I'm just getting started I'd like to just give it a shot with what it's already got. But my other concern is, what it came with.
The LNB it came with is the model with the 2 outputs, one is marked H the other is marked V. To combine these two I am with the understanding that one of those DirecTV multiplexor switches will work, is that correct? I believe Wal-Mart sells them, no? Or at least they used to back when I wasn't looking for them.
If anyone can offer me any advice or links to directions on how exactly to go about adapting this monster into a useable dish again, I'd really appreciate it!
Thanks in advance!
