I often have no freeview signal during heavy rain from Mynydd Machen transmitter. No signal today. Is there a problem with the location of this transmitter during poor weather?

John Bowen :
Reception will be dependant on location, we need a full postcode to look at the predicted reception for you locale, you may not be getting a strong enough signal.
There is another possibility, your aerial connections or downlead may have degraded and water is getting in which will severely affect the signal arriving at your set. How old (roughly) is the aerial and downlead?
