Tv reception relies heavily on the antenna and the fading circuits. Since you can't improve the antenna without drilling holes in your bodywork you can only look at updating your tuner. With the upcoming digital switchover you could get a new tuner and hope you get a new signal. The digital tuner is about £400 used.

I think the antennae are a real compromise, even with diversity. I replaced my analogue tuner with a Hybrid as we have now gone DSO, but the performance of the tuner/antenna leaves a lot to be desired. We are in a very good/high signal area, but the BMW tuner is marginal on some of the multiplexes. As for using it whilst driving, then with digital, forget it unless you live practically next door to a main transmitter.

IMHO, there is no way you are going to be able to replicate a home TV setup which uses a high-gain, tuned 'in group' yagi mounted high up on the roof pointed directly at the transmitter, by using a pair of wideband 'in-glass' strip antenna at almost ground level. Try plugging a smallish set-top aerial into your TV and see what happens ... it's the same sort of problem with in-car TV.

I have to agree with Trapdoor. In the 1950's when the BBC designed a country wide TV system, it wias specifed that all houses should get a signal with a roof mounted directional gain antenna. In areas of good signal strength, a loft mounted antenna could be used.

The antenna was never meant to be moving and so there is no doppler shift compensation in either analogue or freeview TV. It was never intended to be 4 feet off the ground surronded by buildings either.

The fact that it works at all is a bit of a marvel.

A newer freeview tuner is soon to become a nessesity and you cna only hope that your local freeivew antenna signal strength is better than your analogue. You can investigate this by loking at your local transmitters here.

thank you for the replies guys.

it looks like i will just leave it as it is which is a shame as it is an expensive piece of kit that is of no real use (
