[QUOTE="John, post: 989056, member: 175005"] Well, pleasantly surprised myself this afternoon after doing some Cband comparison testing on 40.5West Circular between my existing polariser barrel / single feed combo and the new AV-Comm polariser barrel / Zinwell lnbf...... both systems capable of motorised skew & polarity change. Tweeked for maximum performance on L &R signals using the motorised single feed lnb set-up which up to now i thought it was giving me the best i could muster ..... scan gave me 32 tp's LHC and 31 tp's RHC. Next onto the AV-Comm barrel / Zinwell lnbf combo, tweeked for maximum performance .... this scan taken very soon after the 1st one gave ... 33 tp's LHC and 33 tp's RHC. Using a specific test freq of 3627 LHC , single feed lnb gave 6.7dB on the analyser. Using the new Zinwell combo gave 8dB for the same frequency. Evaluating H/V performance next on 55 & 58West for new combo. Just a few poor camera grabs below of scan results.... [/QUOTE]
