Brad the sum of one ant leg and the feed line needs to be about 120 ft
or 240 ft so as to come out with a high Z for the Johnson match box.
Your lengths or come out with a low Z at the feed point and Johnson
Match Box's don't like that.

1. Antenna Analyzer something like the MFJ or other brand or
for tuning antennas and tanks in transmitters
2. 6 8008 rectifiers
3. Any other ideas about matching my extended zepp to 75 meters,
changing feed line length, added 300 to .001 caps, changed ant length
135 feet to 110 feet on each side,
changed from 120 feet to 150 feet ladder line, Match is 3:1 after
4. Docs for RCA BTA 5F transmitter
Thanks for the help,
