Why are the signal strengths on tuner 1 and tuner 2 different?

Hi,

I have a Humax Foxsat HDR connected to a chimney mounted Sky Mk4 dish and quad LNB via approximately 9 meters of PF100. When I fitted the dish and cables I initially set everything up in the bedroom upstairs and was getting 100% signal and quality on both tuners. At the weekend I routed the cables down through the floor/ceiling to the living room downstairs and connected the box up again. Now I get 90% strength and 100% quality on tuner 1 and 100% signal and strength on tuner 2.

Any ideas why there is a difference between the tuners? I can only think that I have damaged one of the cables but it seems strange to lose just 10% signal and no quality? Perhaps one of my tuners is duff? Or the LNB?

I'm not too bothered about it, just curious.

Or an f-plug, with a tiny filament of the outer making contact with the core cable?:D

Most likely because 1 tuner is using a transponder with a better signal than the other. Swap the cables and see if the signal strengths swap as well.
