Hi Rich,
Mine will cover all the ssb portion of 20. The bottom 5 khz 14.150 - 155
swr is 2:1 Not sure about the double dip you mention, but mine is flat at
14.200 rising a bit higher in the band but not higher than 1.4 and
dropping again to 1.2 at the top of the band. I use the tuner for cw
portion.
Tying this in with the recent thread about do-it-yourself antenna
installation, my main reason for going with this antenna was that I wanted
something small and light that I could install myself on a push-up mast in
the back yard (23 feet). I went with a small tv rotator that is too light
to turn my Mosley. I didn't want to deal with the extra weight of the
Ham IV rotor I have packed away here right now. Also more money to make
the Ham IV accessible. The tv rotor has a remote control that lets me
punch in a 3 digit compass heading and the rotor turns to it.
