OK, I suspect you want need the meter - just use the quality indicators on the TV , and a compass
OR for £17 - saves having 2 people , one to watch the TV and another to shout
to be honest
BUT check ALL MUX on the transmitter - the link i posted gives what channels are on what MUX
Maybe watch the quality for a while and see if it drops or intermittent
It maybe the cables or connections on any cable
How many TV's run off the aerial ?
Maybe an simple AMP may help - Mine did for 1 of the MUX
now have an AMP in the loft as we have a few TVs running off same aerial
