Come to Devon with a big reel of wire under one arm and your 600W PA under the other! (Mine has RIP inscribed on it). I once used a 132ft loaded cliff on 160m by throwing the wire off the side of Ber

Careful, Andy. The last time I operated amateur radio on Portsdown Hill (2m AM!) the Navy Police arrived within five minutes. Mike, G3XDV (IO91VT) http://www.lf.thersgb.net

Yes, thought someone had already tried a dipole up a hill. In that case I won't try dangling a long wire down from Portsdown Hill. If I wanted to install an (amateur) LF antenna at the works QTH (jus

I hope this relates, but we used to lay MF and HF antennas on the surface of the snow or even ice in the Canadian Arctic. When we started it was a big deal to use some poles about 5 or 6 ft long to

Hi Larry, interesting. Especially as some of us recently experienced that wet stuff absorbs a lot of RF. What frequencies were used at MF ? 73, Rik ON7YD Many years ago I did read somwhere an article
