HF ZS6BKW Junior Multi Band Antenna

ZS6BKW - Junior, half size to cover 40-10 meters it actually resonates on 6 bands, and doesn’t rely on a tuner (ATU) to make it work. The design appeared in TT (RadCom) It’s only 45 ft long (13.75 metres), with a 40 ft (6.1 m) downlead.So, it’s a cousin to the G5RV (which only resonates on 14 & 24 MHz), but better as it needs no ATU on 40, 20, 17, 12, 10 and 6 metres.Any length of 50-Ohm coax to shack. SO 239.

Are you a fan of the G5RV antenna?  Then you may be interested in the ZS6BKW antenna.  The ZS6BKW antenna is an optimized variant of the venerable old G5RV.  The G5RV antenna (c. 1946) was designed by Louis Varney (G5RV, SK). The ZS6BKW (early 1980’s) was derived from the G5RV by Brian Austin (G0GSF, formerly ZS6BKW).  He developed computer programs that were used in conjunction with Smith charts to calculate the optimum dimensions for his variant of the antenna.  Read G0GSF’s own article about the antenna.

Construction of the ZS6BKW - Junior antenna is essentially the same as the ZS6BKW except for the lengths of the radiators and matching section ladder line. The wire elements are 13.75 meters long for a total. And the vertical 450 Ohm ladder line is 6.1 meters long.
