Ian Davies:

We still need your full post code. Without it there is no way we can help. Are you sure that your aerial system is correctly installed and aimed? What are the signal strengths of all the multiplexes being broadcast from Mendip?

You asked for help. We can only offer advice if we know where you are in relation to the transmitter.

Ian Davies: Perhaps if you were clearer you might get more constructive comment. On which aerial did you notice this "change" in signal? You've just mentioned an outdoor Mendip aerial the implication of which is you have an indoor one as well, and there's also this Stockland Hill aerial. Are all the aerials "grouped" or are they wideband? Are the aerials coupled at any point before being fed to the TV(s)?
In any event, there has been no change to the local Bristol Mux. I'm 40 miles N of Mendip and getting it on 74% signal 100% quality as I usually do.
I do get occasional variations in strength when propagation changes. I suggest that it was such an event that was enabling you to get the mux of the back of your Stockland Hill aerial, recent weather pattern changes would usually cause some change in propagation.

Ian,i personally had a lot of trouble with the humax brand as regards signal quality,in my case the quality meter was swinging like a yoyo even though i live in a swamp location,its possible yr incoming cable has been affected and the particular channel has disappeared due to suck out,if you can,replace the coax and plugs and see what happens...........n

nicholas MUGFORD: Poscode would be nice, especially since Himax are a good brand, with sensitive tuners, and can bring in too much signal, the symptom of which includes exactly what you've described.

hi mike,i'm sorry,i dont wish to give postcode for various reasons,but one isn't far from beckley,lets say,you can get a picture without an aerial,i just have an indoor aerial,sufficent here,but do think people need to maintain their aerial systems if feasible,the coax wouldnt last forever and some areas suffer from signal twist,some viewers need to incline aerials upward to see if this improves things,n....................
