- That is correct. We used a Force-12 1:1 bead balun (i.e. common-mode choke) on all of the other antennas, including the reference dipole, except for the KT-34XA which came with a 4:1 balun/transforme

- Mosley's PRO-57B claim of 8.5dBd gain on 20m with only a 24' boom is incredible That gain spec originated many years ago when it was common practice to include ground gain (up to 6 dB) in the figure.
