High pressure causing channel loss through "Inversion"

High pressure does not just bring cold at this time of year, it is causing quite random loss of Freeview and analogue reception.

published on UK Free TV

There is high pressure over the whole of the UK at the moment, and this causes the Inversion Effect. This is causing people to be missing a single Freeview multiplex, or have terrible analogue reception on a single channel. The problem may come-and-go or last for several days.

For details, please see What is the Inversion Effect and why does it effect my Freeview TV reception?.

Please check your aerial cables and connections. Unplug all coaxial plugs/sockets and refit.

James Chamberlain:

The current high pressure over the UK is causing the signal problems you and others report. Be patient until the weather changes and all will return to normal.

Hello, it is Sunday 21st April at 19.37pm and I have had no signal in Overstrand, Norfolk for half an hour now. Can anyone tell me what the problem is? Many thanks.

Not without you giving a full post code so we can examine the transmitter information and your reception conditions.

Meantime, check all your awerial cables and connectiopns. Unplug and refit all coaxial plugs/sockets to clear any possible oxidation from them. DO NOT RETUNE.
