"Hi Bob, the balun/choke (ed note model 1116dt) is working out great on the ZS6BKW antenna, I only need to use the tuner on 80/75 and 15 meters plus now it seems that the power company has made changes on correcting the problems with the power lines and my noise level has dropped by allot (S9+10 to S1). As a test case I can very easily get on ...

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).
With an ATU (manual or auto impedance matching device) the ZS6BKW antenna is usable on 80, 40, 20, 17, 12, 10 and 6 metre bands, however the ZS6BKW is definitely unusable on 15m (21 MHz) and 30m (10 MHz) due to a very high VSWR on both bands. The IC-703 inbuilt ATU refused to play ball on 15 and 30m. Sep 26, 2017 · The ZS6BKW worked fine without the need for an ATU on 80M (a very slim bit), 40M, 20M, 17M, 12M and 10M but was untunable on the rest of 80M and all other bands with the TS590 built in ATU. I couldn't find any difference in performance between the homebrew doublet with the SGC at the base and the ZS6BKW.
Marc, N4UFP, and I get together to talk about, build and test the ZS6BKW antenna. This is a much MUCH better performer than the heavily marketed G5RV! If y...
Aug 06, 2015 · Consequently, the impedance at this point is low and on the order of 72 ohms. This makes it convenient to feed the antenna directly with low impedance 50 ohm coax cable. To minimize the chance of common mode currents on the coax that can cause the coax to become part of the antenna a balun is sometimes used. ratio balun. Bill claimed that the antenna is usable on most bands without a tuner (SWR <2:1) by adding a 1/4 λ wave transmission line impedance transformer cut for 15m and changing the balun ratio to 1:1. T h ei ncov f tsw d balu overcome if the feeder end and balun are brought into the shack. Using a tuner the antenna also works on 30, 17 &12m.
