Say I was receiving TV from Crystal Palace transmitter where line of sight
was partially obstructed, but, signal strength and quality was normally good

Could bad weather affect signal and reception? Say from very low rain cloud
or similar

I presume you are talking digital TV, because analogue TV is virtually
unaffected by weather (unless lightning strikes the transmitter ), if you
go to uk.tech.digital-tv they may be able to give you an answer

So why have they for years mentioned that high pressure can cause
picture unterference?
Not that I've ever noticed it though.

I depends where you live. On hot cloudless days in the summer my TV can
be virtually unwatchable on some channels due to interference from
French stations. The transmitter is between me and the coast with
France another 70 odd Km further on.

Isn't the Digital signal carried on the UHF transmission. If you receive
purely analogue and the signal is impaired by atmospheric conditions the
image relects this in many ways by becoming fuzzier with more reflective
shadows. Whereas with digital you get an image which can become blocky or
you don't get an image at all.

I seem to recall you are somewhere out in East Wokingham? If you are,
and guessing a postcode from that area RG40 1PD, and guessing you've
got Freeview (the most common reason for new reception problems these
days), you may be in a fringe reception area in which case, you need a
*better aerial* to avoid problems in bad weather. This is probably a
weak signal problem, not continental interference etc. You didn't
tell us much, so I had to guess... but anyway this is what the
Freeview website says about that area:

"FREEVIEW covers your area for the postcode RG40 1PD ** but you
probably need a new type of aerial.

The search indicates that FREEVIEW covers your postcode but as well as
an box (or integrated digital television) you probably need a new type
of rooftop aerial.

Why a different aerial?

Because FREEVIEW signals in this area use a different transmitter or
frequency than your existing analogue television. Unless you already
have one, you need a different type of rooftop aerial for digital
reception. We recommend a "wideband" aerial."

I would have to disagree with that. Digital TV being quantum in nature,
i.e., you either have a picture or you don't, appears to be unaffected by
the weather but if there is interference then it is usually local in nature,
like the lad with a motorbike who lives opposite, when he starts up his bike
our Freeview TV picture goes blocky.

I remember in the old analogue days with anticyclonic conditions, co-channel
interference/ghosting was always a problem; digital tv is not affected by
this.

Rubbish, have a high pressure sit over the country for a few days and
when it starts to move away you get enhanced proporgation that can
totaly wreck normal reception to co-channel interference. Most people
just don't notice all manner of faults and interference.

I suspect you were a victim of Troposheric Propogation - see:

http://whatis.techtarget.com/definit...333317,00.html

Radio Hams welcome such events of course since it enhances the range of
VHF and low-UHF signals!

If you want to discuss reception have a look at

these are the people transmitting to you
