Hi Mike, I have a dual-band 160/80 meter vertical system that is based on 1/4-wave verticals on 80. I switch in loading coils to make them work on 160. The 160 capability was added as an afterthought, a few years after it had been set up for 80. Perhaps top loading would be somewhat more efficient on 160, but it would be difficult electrically and mechanically to switch out top loading on 80.
The key is many radials, over 100 of them ranging in length from 30 feet to 200 feet, depending on the space available. I won't claim to be the loudest guy on the band, but it does work. And the real key, as everyone knows, is being able to hear (I have a separate RX array). Without really chasing countries (I am missing many easy ones) I have something like 250 countries worked and 38 zones towards WAZ from an unexceptional suburban location. 73, John W1FV -----Original Message----- From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of W0MU Mike Fatchett Sent: Monday, June 02, 2014 12:50 AM To: topband@contesting.com Subject: Topband: Using 80m 1/4 vertical on 160 Is this worth trying? -- Mike W0MU _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
