Six months ago I installed a second aerial on the roof to pick up local news from Hannington as an alternative to Crystal Palace. The aerials are routed through a Triax 3537 combiner. 2-3 months ago the signal for BBC South (Channel 45) deteriorated. I have only recently checked this out and find that it is only channel 45 that is causing problems. Channel 42, ITV Meridian, continues with a good quality steady signal (strength 70% and quality 100%- measured by the Samsung TV diagnostic) but on channel 45 the signal strength and quality leaps up and down between 0 - 50% . A separate TV at the other end of the house suffers even worse refusing to display any picture most of the time. I have bypassed the combiner and this does not solve the problem. I suspect some local interference but can not isolate what might be causing the problem. I would be grateful for any suggestions on what I should check next?
