That is 6-6.5 dB over a dipole. And you believe the little A3
on a 14 ft boom might have the same gain in 20M? NO WAY.
A FULL SIZE 3L20 on a 14 ft boom MIGHT achieve 7-7.5 dBi
or 5-5.5 dB over a dipole (with NO traps). See the W2PV
Yagi Design Book, Chapter 2, for graphs of 3L Yagi gains
vs element tuning and boom length. >>
I use the A-3 antennnas for 'spray' antennas to supplement my stacks. They
are nice little antennas, but there is no way they can even come close my KT
34XA much less mono banders.
