Does The Cold Affrect Freeview Broadcasts?

Indeed it is and often for the reasons you mention but in this case it is a sudden onset problem and water ingress is a gradual process. Very gradual when the water is solid as it is now.

There is rather a large difference between 3dB and 20dB and in any event incorrect antenna installation is irrelevant because the problem onset was sudden and coincided with the recent high pressure so the cause is obvious.

I was just pointing out some random scenarios, that was all.
Well the high pressure has not been that generous for my radio hobby, not as many VHF contacts as I would have liked.

Indeed you were

I've an amateur licence too but I never seem to find the time and energy to pursue the hobby. Maybe when I retire.

Use it while it lasts, the way things are going with these PLT "noise generators" we will have very little usable radio spectrum left.

Freeview use the UHF band and are governed to the same laws of physics as the analogue TV signals.
Freesat is higher in frequency circa 1200MHz. Different scenario here.

You missed out a zero for the Freesat downlink it's ~ 12GHz

I was close.

I'm not sure what will happen there. I actually own some and mine generate no noise on any HF ham band that I can detect although I wouldn't like to be a SWL near them. I'm moving soon and I've network cabled the new house so I won't need them any more. Ethernet can screw up VHF though as I found with my weather satellite receiver - I had to change over to STP cables near to it.

Yes, I had an issue on 6 Metres with noise and tried many tricks in the book to resolve it, the noise was typical around S7, I made up some shielded Ethernet cables and it was reduced dramatically, could still here faint carriers but the were less than S1.

I think my freeview is playin up cos of the cold. It seems to be stutterin and stoppin more than usual. Tried to adjust arial and retune the tv, but its no good, still keeps breakin up.

we lost the same channels about a week ago for a day or so. Since Wednesday we can't get any TV channels but then the aerial is covered in snow and ice so I'm hoping it will all come back once the thaw starts.

...there was no signal, that's on Freesat. Went and tried the Tv in the lounge which is Freeview and it was fine...

A bit of ice on dish - as I found today. Not visible from a distance and in my case easily removed by pouring warm water over dish & LNB cover - presto, reception returns. Another reason not to place your dish on top of the roof.
