Thanks Chris
I have fiddled with all aerial connections as suggested and low and behold my signal strength for BBC and others had now upped to 56%. I can't believe it could have been simply a poor coax cable connection but it seems likely for since fiddling with the connections over one hour ago single strength has maintained. I think it was the connection to my Youview box that was causing the problem or there may be a problem inside all may be revealed if the problem returns.
Many thanks I will keep my fingers crossed all is now well.

It is well known that poor connections will affect the signals from the aerial to the TV set. Any poor connection will cause problems, which is why we contributors (who have seen it so many times) suggest checking aerial cables and connections. Coaxial plugs and sockects can get corrosion/oxidation on the contact surfaces and that causes signal [roblems as well - hence the suggestion toi unplug and refit hence removing that corrosion.

We have been experiencing loss of signal (sometimes for half an hour but more usually just a few seconds) for the past two weeks. We a complex of 30 properties served by two main aerial dishes. I have been advised that our equipment is okay. Wondered if you had any suggestions

There is no known problem with the transmitter so there has to be a connection problem at your location. Please note that Freeview dooes not use dishes but terrestrial aerials similar to those used for BBC2 since the sixties, though nowadays they need to be a wideband design.
I suggest that you carefully check all the aerial connections throughout the system and if there are any coaxial plugs.sockets then unplug and refit those. That also applies to any screw type 'F' connectors.

If you meant aerials rather than dishes and are actually getting Freeview not Freesat, there has been some testing going on at Mendip in preparation for the forthcoming retune events (eg. see post above mine) and there have been breaks in transmission as you have described, usually late in the evening.
Note, all those channels are not on air at time of this post, & retune events are on 4th April, 5th June and 19th June.

All,
I have quite an old set and have to manually scan all mendip multiplexes to avid being flooded by wenvoe.
Is there a definitive list of channels after each retune event?
Would I be right in thinking the ones now (after 4th April 2019) are:
32, 33, 34, 35, 36, 48, 51, 55 (HD), 56 (HD) = 9 in total

Adrian: According to Digital UK the current allocations are 32/54/58/48/33/52/36/35 (also 51 if you're within the local mux coverage area). There will be further changes on 5th and 19th June. If you put your postcode into the Digital UK checker and tick detailed view it will show you all current and future mux allocations predicted to be receivable at your location.

Since todays retune I can't get BBC digital - but I can get BBC HD my post code is BS35 2HY - so I should be on the Mendip transmitter.
Is there a signal problem?
