The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Mendip (Somerset, England) mast?

Very basic questions for weak reception of Mendip broadcast:
Timeline - changes take place in September 2011 and 'early 2012' - are these likely to improve reception of present low power channels?
Aerials - I have a roof aerial which is at least 12 years old, it has 17 cross bars in horizontal plane. Your recommendation is for Group E/W - is this a type of aerial covering both groups or should it be either Group E or Group W?
Where on your web site can I find pictures of the different aerials to compare with what is available on-line?

Christopher Innes: You should already have excellent reception from Mendip, if you don't then you probably do need a new aerial.
You can use a group C/D, group E or a wideband aerial.
See Freeview reception - all about aerials | ukfree.tv - independent free digital TV advice for details of aerials.
At your location, as long as the aerial is on the roof a standard aerial will be perfectly fine - use satellite-grade coaxial cable for the best reception results.
A larger aerial may overload your receiver.

Christopher Innes: If you are presently receiving the BBC and ITV1 channels in a satisfactory fashion then I would wait until after the changes take place in September before making a decision to alter anything, the reason being that provided the person who fitted your aerial 12 years ago didn't choose to "over" cater for channel 5 analogue being on much lower power than the other analogue stations then the present aerial should be OK for Freeview without compromising anything.
It should be said though, that even with the changes that's being made in September you will really have to wait until early 2012 before everything is finally stabilised, as some of the Multiplexes will still be transmitting on a reduced output up until then.
You should have a study at the info on the top header to this page, as you will find most of what you require to know amongst the wealth of info there, including by the way the coloured end caps that are used to identify aerial groups, these end caps being on the common horizontal crossbar that holds the elements, although you possibly might not see them easily on a roof mounted aerial.
You should also carry out a signal check (associated with TV's tuning menu) to see what the strength / quality indications are on each of the Mux channels you receive, the MUX channel numbers / frequency (in brackets) indicated at the bottom of each section.

Steve (Melksham),
The replacement Humax box seemed also to have a somewhat wobbly centre socket for the coax plug to go into, but behaved totally differently when subjected to the coax wiggle test - not a hint of a hiccup or hesitation; rock solid. Its now on for a couple of weeks test including recording (where it used to show trouble).
I'm still wondering whether your Panasonic might be doing something similar, even if the aerial plug is a good fit.

when freeview first came out I used to get all the channels but for the last 2 months I am miss channels 11,15,18,19,21,22,24,25,29,35,44,45,47,48,82 and I have had now signal on channels 10,23,26,27,30,31,34,43 and 46. I have 2 tvs both on different freeview boxes and both on different aerials, one is new and the other is old. Both aerials are outside on the roof and I have retuned them both over 10 times what is wrong.

Hi. Block of 6 flats in Peasedown St John . Communal TV aerial on the roof is a 14-element group c/d contract aerial pointing at Mendip (but first it points through the branches of a tree about 12 feet away and then a line of trees about 40 yards away on a hill). Distribution amplifier in the loft of one of the flats. The old analogue service was watchable but fuzzy, and an additional signal amp near the TV set made it close to perfect. Freeview has frequent dropping-out of sound and blockiness or freezing of pictures; the "no signal" message is less frequent but still multiple times per day. Without the set-back amp, Freeview shows only the "no signal" message.
Are any of the following likely to improve the reception?
* relocate the aerial to miss the nearest tree?
* put it on a taller pole to maybe help with the next line of trees?
* replace the aerial with a Log 40, Yagi 18, or DY14WB?
* I know nothing about the quality of the distribution amp; might it be better to replace it with a masthead amp and a splitter?

MFPA: Yes, the first two options are the best, you can't compensate for the loss of signal to the trees with a larger aerial or amplifier.

We live in Enmore
Have lost several channels recently - Fiver, 5USA ITV4 etc
Also BBC channels are pixelating
This has only happened in the last few days, Mid May 2011 onwards.
Is this related to Low Power on Transmiter, as we've had good reception until now
