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....................

Hi,perhaps just for test purposes,an indoor aerial could be tried,just to ascertain local conditions.n.....

hI,I think everyone has to take a step back and learn something,UHF radio waves are like light waves,in spite of high tx powers,there are areas that are below the radio horizon,signals can be bounced off local objects and the signal field will cancel ,sometimes putting a tv aerial on the roof may not be the best place,good signals can be found in funny places,perhaps freesat maybe could be better option for certain people,If people listen to advice then that would a way forward and not run around like a headless chickens...n

Without any idea of where you are located we cannot offer any meaningful advice.
Bear in mind, also, that we contributors have knowledge and experience between us that we try to use to assist in answering questions, mostly from people having reception difficulties.
