[QUOTE="ProDave, post: 4791, member: 175209"] Okay, onother question. I installed the second LNB on my dish on Saturday. I took the receiver and a portable TV outside, and started off just holding the LNB in front of the dish to find out where it needs to be mounted. When I found the correct position, I set out to make a bracked to mount it permanently. It was actually very easy, a standard plastic waste pipe clamp fits the 40mm collar nicely, and a couple of spacers and a few nuts and bolds and one sturdy and neat mounting bracket. It ends up with the second LNB being just to the right of the original one (looking into the dish) and very slightly lower than it. I also rotared the new lnb for best signal, though it appears not to need any skew. The feedhorn of both LNB's are almost touching, which means 6 degrees apart is the minimum you can do like this. If the two satellites you wanted were ledd than 6 degrees apart, the LNB's would have to overlap each other which of course would not be posible. Now my question. I am a bit dissapointed with reception quality. There is a huge variation in signal strengths over the different channels (I can receive all 19 analogue channels listed on Lyngsat) Some (e.g TBN) are near perfect, while a couple are very poor indeed. The main one I am interested in, BBC world is watchable, but has some sparklies, and I can't improve any more, this is the one I was watching when I aligned the lnb. So is this what I would expect with an 80cm dish looking at 19.2 degrees, and an offset LNB for 13 degrees? Obviously if using an offset lnb like this will give worse results than a dedicated dish, but is what I am getting as good as I can expect for this setup? [/QUOTE]
