Spyware: UHF signal is not prone to rain fade. The phenomena generally affects frequencies greater than 8 GHz. So you need to tell us whether you actually have LoS (line of sight) to transmitter.yes, i have line of sight to the baxters knob transmitter in wellington. i'm so close that when the installer came to put it in, he remarked that he could leave aerial lying on the ground and still get super strong signal.
i do have a splitter attached to the wall socket coming out though. one cable goes to my tv with freeviewHD built in, the other goes to my freeviewHD recorder. both signals are affected when the rain comes, although one not as bad as the other.
do you think that it could be a cable quality problem?
