The symbol shows the location of the Mendip (Somerset, England) transmitter which serves 720,000 homes. 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?

I have a 15 cm lap top ariel that is magnetic so i stick it on my radiator in my room I have found the sweat spot that gives me all channels for days then suddenly, randomly, i lose channels. Is this due to atmospheric conditions from mendip to kingswood bristol? or a problem with interference or do you change the signal strength daily??

Greg Harper: If you need to get your indoor aerial in a certain spot for it to work then you probably only just have enough signal. Any slight change in reception conditions can cause the signal level to drop below the point where enough is being received to decode the channels being broadcast. Transmitter signal strength is kept at the same level unless there are engineering works taking place, it doesn't vary each day/week.

Greg Harper:

Further to that said by StevensOnln1, a laptop aerial is unsuitable for TV reception. It is designed to operate with WiFi signals in the 2.4 GHz band whereas Freeview digital TV is broadcast in the 450-800 MHz range. That means your WiFi aerial is not of the correct dimensions for the TV signals to get satisfactory reception. The size of the elements is critical for good reception.

In Kingswood, not all homes can get signals from Mendip due to the terrain and so there are smaller local transmitters nearby. Giving a full post code would reveal those that may be beneficial to you. You should also invest in a proper log-periodic aerial that is specifically designed for use with Freeview signals that are currently broadcast and also for the planned future changes.

Firstly we are very pleased to say we have a really super reception on the Freeview channels in Dorset, via the Mendips Transmitter. We have an up to date HD/4k ready top box, and a smart TV. The only reason I mention this is, we cannot understand (after seeing this advertised on Freeview) why it is we cannot get the "True Movie channel", advertised as channel 74 on Freeview. I checked my software updates and rescanned my box to no avail. Si I contacted who has advised me The Mendips transmitter has not subscribed to this channel. Can anyone tell me why this is please?
Thanks Mike

Mike: True Movies is broadcast from Mendip on the local TV multiplex alongside Made in Bristol, which has most of its signal focused north towards Bristol and the surrounding areas, with only a limited amount of signal in other directions. You can see the coverage area if you click the LBSH label on the coverage map at the top of this page.

Mike: We need a postcode, but if your tuned to Mendip, even with a HD tuner (btw - what is a 4K ready set top box?), your not going to get it, because, as their website says…vies , its available on only Sky, Virgin or Freesat.

So if you do want that channel, unless you subscribe, you'll need a dish.

MikeB: True Movies has been on Freeview LCN 74 on local multiplexes since October (initially rebranded as True Christmas). The channel listing on this website for the local muxes is extremely out of date as it still lists QVC Extra which ceased broadcasting on Freeview local muxes in September 2015.

Mike: as mentioned by StevensOnln1, True Movies/Christmas is being broadcast on the Local TV Mux (LBS UHF Ch51), so if you can't get 'Made in Bristol' (LCN 7) or 'True Crime' (LCN 60) also Kix (LCN 127) then you won't get True Movies. Not only is the LBS signal directional but it is also lower power.
MikeB: The listings here by Briantist: are out of date I'm afraid.

Others reporting occasional loss of channels/muxes - propagation conditions can affect the received signal strength of some of the muxes if you don't have a strong signal, particularly the LBS (Ch51), COM7 (Ch33) and COM8 (Ch35) so if your received signal is marginal you will experience occasional loss especially if interference from other transmitters on those UHF channels gets stronger.

We are experiencing reception problems yet again in our area. We all have to use boosters or else we receive next to nothing, but for the last couple of days we have lost Itv Ch 4 & Ch 5 and various others. The Bbc channels are picked up on a rescan but pixelated and un watchable. For some reason Dave is ok but not Dave Ja Vu. Can you advise if there is a transmitter problem as our signal quality has dropped to 1 or 2

Can you advise if there is a transmitter problem as our signal quality has dropped to 1 or 2. The aerial is on the roof and I have checked all the connections,. Having consulted with my neighbours , they are all experiencing the same issues,and therefore any help in reporting this would be appreciated.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
