there are no reported problems with the Mendip transmitter. If there were several hundreds of thousands of people would be complaining.
It is more likely that your system has some poor connections in the aerial feed to the equipment. Start by checking that all the aerial connectors are pushed in correctly and have no corrosion (simply take the aerial plugs out, check they are tight on the cable and then re-insert them in the socket they came from).

There is a hill just under 10km from you in the direction of the Sandy Heath transmitter. If that has trees it is likely to cause reception problems when the leaves/trees are wet.
Rather than retuning, which risks losing even more channels, check all your aerial connections carefull.

We need a full post code so we can determoine what the transmission and reception conditions are for your exact location. As there is no reported problem with the transmitters in your vicinity, it is likely to be some other cause.
Would you please check the signal strengths reported on your television for the channels causing you problems.

Dan:
Before you try to retune, you must check all your aerial connections first. They must be clean and tight with no chance of slipping out.
You should also check the signal strength reported by your TV set (the User Manual will tell you how to do that on your particular TV) and then report them back to us. The reason for this check is that having too strong signal often appears as you describe.
Let us know how things are after all that and without doing any retuning (that is a last resort and is likely to cause a loss of more channels!

You do not 'retune' a TV aerial. The availability of of any particular region depends on what the transmitter is set to radiate. To find that out, we need your full post code.

Heather:
Further to that said by MikeB, you *have* to use an aerial to get Freeview of any sort. Do you have an aerial fitted to your home? If not you need to have one fitted. If you do have one, find where the cable from the aerial comes into you room and hopefully find either a coaxial cable that you must plug into the TV aerial socket or else there may be a wall plate with a coaxial socket. In that case, get a coaxial TV flylead and connect it between the socket on the wall and the socket on the TV set. Then try a retune of terrestrial services only.
It always helps us to help you if you provide a full post code for your location.

I have worked in the TV industry since 1960. The concept of RF signals causing illness has been mooted for many years and has no validity unless you are a TV transmitter engineer working on a 'live' transmitting aerial. You can stand directly underneath the transmitting aerials at Crystal Palace, in London, and be perfectly safe.
The general population has been 'bathed' in RF radiation for as long as man has been on the Earth and the natural radiations were present long before then. Man-made RF signals have been around for more than 100 years and almost no one has suffered (there are a few who claim to suffer but no scientific evidence has been found yet).
TV transmitters will not be used for 4G transmissions, they are designed differently. A separate transmitter has to be built for 4G and almost always it uses a separate mast for the aerials.
When 3G started, Ofcom authorised an organisation called 'at800' to inform people who might be affected and to provide those who definitely were with filters. It has nothing to do with any health issues purported by the 'doom sayers' to exist. With 4G that does not seem to exist as the 4G signals will largely use the existing frequencies that have been used for some TV transmissions but these are being moved to other frequencies to all safe operation of 4G.
Stop worrying about nothing and concentrate on whether the house is suitable for you and your family.

There could be many causes. For us contributors to offer any meaningful advice we need to know t=your full post code.

Dan:
If you click on the 'digitaluk trade' link at the bottom of your post, or try Coverage Checker - Detailed View yiu will see that your post code should get COM7 easily despite the lower power than the 'main' services. It is on the horizontally polarised service but is not on the vertically polarised service. So any new aerial should be set for horizontal reception to get these channels.
Hope that helps?

To be able to assist we need a full post code, PO1 is not accurate enough as it covers such a wide area.
