Hi Stefan, I saw a QRSS signal came from 70km away was shown on his grabber so far. He said the gain of two electrodes earth antenna is -3dB comparison to 40m high of vertical LF antenna. The advantage is ease of installation, simple strucrure and strong in a storm. 73, 7L1RLL Rick On Fri, 2010-09-24 at 01:35 +0200, Stefan Schäfer wrote: > Hello Rick, > > What is his best RX distance so far?
