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?

Hi, I am wondering why I am unable to pick up Film4? I have a Freeview Digital TV and live in central Stroud. Has it got something to do with the power of my ariel or does the Stroud area have limited frequencies? I have tried retuning.
Many thanks for anyone's help?!

Jonny: If you are receiving from the Stroud relay, or "filler-in" transmitter, then you will not have the Commercial (COM) channels; it only carries Public Service (PSB) channels.
For a list of which services are carried on which multiplex (i.e. which are PSB and which are COM), see:
DTG :: DTT Services by Multiplex
The COM channels only broadcast from the largest transmitters as their prmiary objective is profit and they have no "Public Service" obligation. See here:
Londonderry (Northern Ireland) digital TV transmitter | ukfree.tv - 10 years of independent, free digital TV advice
If you are receiving from Stroud then you may be able to receive the full service from another transmitter such as Mendip or Wenvoe. The latter carries Welsh regional programming and you may be able to use a separate receiver for it (or use Wenvoe as your main transmitter and Stroud via a separate set-top box for regional programming).

Jonny: I would suggest that you're not likely to be able to receive from Mendip and that you're only option in the centre of Stroud might be to receive all channels from Wenvoe and regional PSB channels from Stroud. Unfortunately due to the channels (frequencies) used by these two transmitters being interleaved, you won't be able to have the two feeds (from each aerial) combined so as to feed it into one receiver.

Jonny: probably best to check your postcode on this website to see what your forecast coverage is likely to be.
Depending on where in Stroud you are, I would imagine the hills surrounding the Five Valleys may get in the way of the main signal from Mendip. In that case, you may be getting your signal from a local public service relay. For example, Stroud has its own relay (https://ukfree.tv/shutdowndetail.php?tx=SO836077), which you may be getting if your main BBC1 channel comes in on UHF 40 (on Mendip it comes in on UHF 49).
If it's only relaying public service ("Freeview Lite"), then I think you'll only get PSB1, PSB2 and PSB3. Since Film 4 is on COM6, a commercial set of channels, you may not be able to get it at all.
Are you also missing channels such as ITV4 and Yesterday? Can you get Dave or ITV3? These are all on commercial UHF channels which the Stroud transmitter is not relaying.

HI been through the reset procedure on my mums Samsung TV which is about 2 years old there is no free veiw box so i think the tv has the freeveiw tuner built in it was working fine before event now no BBC
their postcode is Sn2 7Pr which is Swindon they live in community housing so the service is provided by landlord for all the tenants they have another tv in the bedroom which uses the same Ariel point and this receives all the channels after it was retuned I have done the reset procedure scan minus the Ariel lead unplug power off wait 30 seconds power on scan again I removed the set in the bedroom from the point before starting and finishing procedure but to no avail the set did find BBC around 800 MHz but the picture was pixellated with no sound it used to show as channel 1 and channel 2 now the first Channel is number 3 but to no avail any ideas as their set seems to be the only one that's not picking up BBC

Whilst it is often not advisable to diplex two aerials into a single feed there is another possible solution, one that I used when living in Swindon and could receive from Mendip and Oxford main transmitters. Both aerials were mounted on a good strong pole, thicker than is normally used, and each had a separate good quality downlead into the lounge by the TV set. They connected to a coaxial switch that had two inputs and one output, so only one aerial was connected at a time. Simply moving the manual switch allowed selection between sources. The switch has to be a good quality coaxial one and fully screened to avoid picking up interference and to maintain the integrity of the coaxial connections. It must be designed for 75 Ohm coaxial UHF systems, can be either IEC coax or F-connector but not BNC connectors. Works with all UHF TV signals with no problems if cables and connections are made properly. You'll need to search for one but avoid any 'automatic' ones.

Pete Green: Transmitter engineering is a bot whose job is to scrape the information from official sources. In this case it is from Digital UK, as the presence of its logo denotes.
