Or if you don't want to or can't easily alter the antenna, lengthen it
electrically by adding a small inductance (10nH) in series at the feedpoint.
Say 12 turns on 3" diameter former (plastic bottle, whatever). If you
lengthen the wire to 86ft you will have a 5/8th wavelength that you should
be abl
Shortening it to 53 feet should avoid being an exact half-wave on most bands.
You might try that first. If that doesn't work, go to 44.

Hi Phil,
Shorten the radiator to 44 feet, but leave the counterpoise alone for now.
The 65 foot length is nearly a perfect half-wave on 40 meters and will
present a very high impedance, possibly beyond the range of your tuner. The
shortening won't help you on 80 meters, but if you can lengthen t
I'm on vacation with my KX1 and my antenna isn't doing well. It is 65 feet of
telephone hook up wire and a 15 foot counterpoise. Nicely up 20' in a tree but
getting no tuning on 40 or 80 but tunes nicely on 30 and 20. I'm on the road so
can't make too many adjustments. Any emergency fixes so I c
