Re: Long Wire Antenna Performance Questions

Great! Many thanks Heinrich. Sooner or later I will try your configuration: on the roof I can arrange to find a 25m for the wire but for safety reason (an not to quarrel with neighborhood) I can't raise poles more than let say 3m height. Do you feel this can be a big problem for the efficency of thi...

Re: Great experience with PAR Electronics EF-SWL

;) Hi Heinrich, hi all. Perfectly agree with you: I believe in my experience and I believe in sharing info from guy I can trust... Once someone used to say: "It was told by television"... now the mantra is "It was told by twitter, facebook, google..." The problem is still the sam...
