Smart TV problem

It's something to do with how television signals are broadcast and bounced off atmospheric layers but I must admit I'm completely out of my depth here. Nevertheless, could that be a possibility?

The ionosphere isn't that different though, I'd have assumed the propagation between high and low pressure's ins't much different... but I've never been much cope with low frequency radio waves.. ask Clive.

Oh and its wifi here, won't leave the house...or not far.
Clive:
I can't see how the pressure can affect propagation. :-\
sam:
I mean it will affect the refractive index and hence some light is likely to be attenuated or shifted... but I think its the moisture content that causes the highest scattering...

I'm enjoying the high pressure, since our local TV transmissions were modified (part of the 5g rollout) I haven't been able to get my favourite channel BBC4 HD because they now transmit it from a low power transmitter instead of the one they used to use. High pressure seems to be be the most favourable condition for it to magically reappear.
I have bought a new wideband aerial which I did plan to put on the roof instead of our current loft aerial, however I then remembered Rod Hull and decided against the roof idea. :crazy:
