I have been interested in Ground Tuning Units since working G4AKC/PM groundwave from a SOTA summit, the Old Man of Coniston - he was operating trolley based pedestrian mobile utilising salt water groundplane to maximum effect - I broke in after a conversation with an Australian, and this was May this year. He must be getting out well with 1.2 million hits on QRZ.
Has anyone experimented with Ground Tuning Units during SOTA activations? My most recent web scan resulted in reading the following article which really does a very good job of explaining ground tuning units, how they are constructed, how they work - and in particular the difference in operation over salt water and on rocky summits.
