Not having experienced this myself even though I live a few miles south of Swindon, I have a suspicion that there may be some atmospheric affects causing this phenomen, though no proof of that. It has been noticed before that warm weather with high pressure areas tends to produce unusual loss of signals.
If it happens, please do not try to retune your TV or set-top box.

You may well have lost programmes by retuning unnecessarily. To get them back on the bedroom TV, take it downstairs and plug it in where your other TV is, being careful with the aerial connection to get that fitted properly. Then try another retune on that TV set. You may well find the programmes are back again. If so, take that TV back to the bedroom and reconnect it - bt *do not* retune again! Do you still get all the programmes on both TVs? Let us know please?

It could just be the weather that is causing it. There is a well documented phenomenon that disrupts TV transmissions and there is nothing that can be done about it. Do not retune your equipment else you could lose all programmes.

To me this can be a non-issue as the safest way to avoid such pitfalls is to not connect the equipment to the internet at all. So don't put the RJ45 plug in and don't enable the WiFi. Thus not access for the nefarious.
You cannot every prevent some people (described variously as fools, idiots, brain-dead, nasty, etc) from attempting to do things that hurt/harm other people and doing it via the internet is the current 'in thing' to do. Next week/year they will have something else to amuse their brain cells.
All we can do is to protect ourselves by not offering them any access mechanism, so don't plug in the internet.

But not yet available to all! BT and Wiltshire Council tell me that they will only start the assessment in our area next year at the earliest!

Yes. The dish 'collects' the signals from the satellite in orbit above the Equator and the LNB (Low Noise Block) that is fitted on the front of the dish converts that to be fed down the coaxial cable into your satellite receiver. The same dish can be used for FreeSat or Sky.

It certainly does not help! It is best to mount an aerial away from any conducting material, such as an aluminium roof, etc. The metal can upset the way the aerial should work and give unexpected results.
Some years ago a copper domed roof caused a total loss of reception for six houses in the same road, the roof 'bending' the RF signals away from that part of the road!

Have you tried retuning the Freeview box? Many changes have happened since you last used it and it may not be set to get all the other programmes that seem to be missing.
Let us know if a retune is, or is not, successful, please?

The clue is in your post when you talk about 'sometimes full strength'. That means you have too much signal strength and the set is struggling to maintain your viewing. You need to reduce that signal strength until you get relaible reception and display of the programmes. An adjustable attenuator, such as the one shown at http://www.amazon.co.uk/L…YPY, would probably help. Start by connecting it at the aerial input socket at the back of your TV set (or Freeview box if you use one) and gradually reduce the signal until you have all programmes reliably.
Other adjustable UHF attenuators are available.

Just a thought that the cable feeding the Samsung may have a higher attenuation so less signal is reaching the set, perhaps. Might be worth trying replacing that cable and making sure that you are using outputs from your distribution amplier that give the same signal levels (some have both high and low outputs).
Please let us know if that helps.
