Hi Gordon, I was tempted to buy at a Rally but when you look at the asking price and see that CPC is selling a single output dual frequency/dual polarisation LNB for about 5 including VAT with a stated (but suspect !!) NF of 0.2dB !! CPC also sell a DC block/injector cheaper than you can but the connectors for it.
I had no trouble receiving the local beacon which is just less than 1km I suppose. The signal did disappear when the leaves came out on the trees. I can confirm these newer LNBs are quite stable I can receive the beacon for minutes on end using an FRG-9600 as the 618MHz IF on SSB mode.
I find a 0dBm to +10dBm source around 144Mhz fed directly to a Marconi diode mixer/detector provides a good marker signal for local comparisons and tests.
