Has anybody had any experience using a helical antenna for
transmissions. I put a small helical antenna (65' 14# wire, 172 turns
on 1-3/8" dowel) on my antenna tuner: on 40 meters (7MHz) the SWR was
about 8:1; on 15 meters (21MHz) the SWR was 1.6:1). I thought the 40M
would tune better than the 15M because 65' is about 40M's 1/2 wl.

My antenna tuner manual suggested a balun to tune in any band that
doesn't initially tune-up. I'm thinking the ubiquitous 4:1 balun.

Suggestions, comments?

Tnx,
