[QUOTE="stephenG, post: 887216, member: 402344"] Yes I tried optimizing the signal for LNB skew and placement of the neck of the LNB in its clamp. Using the Freesat+ box this morning I tried manually checking the signal strength for each of the transponder listed on kingofsat on Astra 2E and 2F. Astra 2E : All transponders on the european beam are good with most 90% signal or better and a few on 75% signal, but UK spot beam all transponders 0% signal. Astra 2F : I don't know if there are separate beams, but far as BBC/ITV signals go I can only get a signal on 10994 H (TID 2036) and also on 11052.75 H (TID 2063) both 75% signal, all the other BBC/ITV transponders 0% signal, otherwise 75% or better signal for all non BBC/ITV transponders except 12574 H and 12581 V both 0% signal. The anomoly of 10994 H and 11052.75 H might just be down to TX on a bit more power...who knows... So I think I am pointing to the correct satellite(s) and unless I have a very precisely adjustable fixing bracket as opposed to the usual U bolt clamp etc.. I doubt I can get it better, I spent several hours trying to get it as good as possible yesterday. Actually I now not very convinced another LNB will solve the problem as the existing one has good snr and gain characteristics. The issue would appear to be a loss of signal strength and not loss of gain, which of course means a bigger dish..... However I am reluctant to splash out as a bigger dish means what.. 130cm, 140cm, or even bigger.. ??. The difference in gain at 10.45 GHz between the Gibertini 94x100cm and the 110x120cm is about 1.5dB, and it doesn't seem to have made much difference. Time for lunch.. and a rethink. [/QUOTE]
