David Williams:

As I can't see another post from you here, I'm not certain what your comment refers to, but the context suggests that it's in reference to my reply to Hywel on 30 December 2019!

If so, I'm sorry that you don't appreciate a moderately lengthy technical explanation from this independent (free) helpsite about radio wave propagation and Tropospheric Ducting and how can be affected by weather conditions.
You can always talk to some radio amateurs or use your search engine to find similar explanations around the www.

It seems you don't realise that transmitters (of virtually all types) have to share frequencies, not only in the UK, but across Europe and around the world, and this is all subject to international agreements. The powers have to be such that they don't cause to others elsewhere. You can't simply just turn up the , otherwise you'd have to turn it up somewhere else to make sure their signals weren't wiped out by the other, you'd simply end up in a vicious circle and just wasting electricity to produce the higher powers.

There's also a big difference in making sure that reception of the Public Service Broadcasters is as reliable as possible for I obvious reasons, especially if weather conditions could lead to potential interference. sharing is generally less on the the PSB's use. Some of the commercial multiplexes can't have the same "luxury"!

COM7 is a temporary HD which in any event will be closed by June 2022, and transmits on UHF as a single frequency shared by the 25 main transmitters that transmit it. Local multiplexes are only intended to cover specific local areas. Both of these multiplexes will be lower power than the main ones.

Briefly, back to Tropospheric Ducting. There just happens to have been some around recently. No doubt climate change has a bearing on it seeming to occur more frequently. Sometimes there is information posted by Freeview and the BBC (poorly explained as it's not just "high pressure" but can often come with it).
There is information at present, but how long before it's removed is unknown, you may find it in the following locations -

richard k greenfield: A aerial (such as a log periodic type) is generally recommended, unless you are somewhere with a weak , where a grouped aerial may perform better. If you provide a full postcode we can check, or any reputable aerial installer should know what conditions are like in the local area.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

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.
