Hi Mark,
I live about 7 miles from LBA and I am at 150 metres asl, not clear in every direction unfortunately.
I have the Radarextender external aerial from W&S.
At the moment I am receiving 420 m/sec and have 156 flights in Myflights.
I am in a bungalow and the aerial is on a pole about 2 metres above the chimney stack, very long lengths of old coax though.
Terry
