Robert: As a general rule, if the signal gets worse during rain the usual reason is that the water is getting into the cables.

You would normally just replace the aerial cable with a new run. Satellite-grade cable is the best to use if you are going to do that.

Christine:

Brian - thank you. I've a feeling we did unplug the booster things, but will double-check again. Come back, analogue, all is forgiven!

Robert - I noticed the same effect on the Com muxes last night here in Banbury although the PSB's were absolutely fine. I used to notice the same thing happening when it rained on the old MUX2 (now D3+4) which used to broadcast at similar power (10KW ERP) & in 64QAM mode on C68. The will problem will probably resolve itself next April when the COM muxes power up to 50KW ERP.

Brian/David thanks. I think we will live with it for now, we have 4 aerials. We have over the last year replaced practically every cable, plugs, outlet plates costing hundreds of pounds when the boosters were added to compensate for the poor signal strength so a few months more just to see won't hurt.

Hi Brian, yes I was very aware of that so removed the boosters after the 28th, and things were fine but within a couple of weeks once again we started to get break up on the weaker channels so put a number of boosters back which stabilised the single again, as I say until the night the rains came.

Robert: And, as we have been over this before, you have already replaced the cables, because the usual reason for problems during rain is that water is getting in the cables or connectors causing a short circuit...

Heavy rain or a thunderstorm can certainly interrupt signals. I've see my Sky box loose signal for seconds and sometimes minutes at a time during heavy rain. Then it comes back by itself. Surely if water had got into the cables, the interruption would have been longer? During the weak freeview signals of the last few years, my freeview reception has certainly been affect too by heavy rain.

Bill: They are different systems, rain is a problem for satellite reception because the signals come from a satellite over central Africa and a very weak indeed and at a higher frequency.

Indeed, it is not normally the rain that is falling on you at the time that effects satellite reception, but that at some distance away.

As I said, rain cannot effect Freeview reception directly, the issue is the rain water getting into the cables causing a short.

I have a Philips DTR200/05 Freeview Box using Oxford Channels 53, 55, 59, 60 and 62. After swich over in October 2011 it would not hold all the channels after auto search when I switched the box off. However I have now only used manual tune on each channel in sequence, deleting stations I do not watch. So far the stations have all stayed tuned after switching off. So will not use auto search again.
Not sure why this works but perhaps it may work for others.
