The Ultimate Guide to 11 Meter CB Antennas states correctly about the 90 degree phasing harness, however the choice of cable will make or break the operation. RG-133/U (95 ohm) is the best to use for the harness. RG-63/U (125 ohm) is easier to find but causes more of a mismatch when used with a 50 ohm main transmission line. RG-59/U cable is used for co-phasing antennas to obtain gain, not for a circular polarized antenna system.

As was stated in one of the responses: When using circular polarization the signals are down 3 dB in each plane as a result of the phasing harness. Thus to get the same range results for a 100 Watt system using either Vertical or Horizontal polarization, will now require a 200 Watt transmitter.

It's all academic since it has been shown that a skywave signal starting as vertical or horizontal will arrive as an elliptically polarized signal anyway. That was discussed several months ago in a QST article.
