I tried a signal booster. All it achieved was to recognise channel 7, but badly pixalated. Still no channel 2
Panasonic advises me I might have interference from power point too close to the antenna, setting up a magnetic field. I am going to try setting the unit at a friends home near here tomorrow. He has twin tuner if this does not work out it goes back for exchange. If that one fails I get refund and try another brand.
This morning did a setup on friends 2 TV's. Works perfectly on both, returned home, same as before. Turns out this friend has a signal booster (amplifier) on his antenna pole, as well as the power point transformer he loaned me. I will be buying a complete signal booster as you have suggested. Thanks for your help.
