The ZS6BKW antenna is a better match for our bands than the G5RV. The method of construction and tuning is essentially the same for both antennas but the dimensions are different.
Here is the ZS6BKW antenna installed at AK6R fine tuned for the CW/FT8 frequencies on 40-20-17-12-10 meters. An excellent antenna when installed at 30 feet or higher and no tuner required avoiding the tuner losses and constant retuning. If you want to work all bands from 80-10 install an antenna tuner between the 1:1 balun and the amplifier and ignore the 39/40 switch.
Is this the best FT8 antenna? – I think so as I has made over 70,000 contacts and it still is a proven winner -Good world wide DX, easy to install, no tuner and takes full legal limit.
Here are several different 1:1 baluns you can use depending on power requirements:
Got an electronic interference problem on your boat or RV? Do you hear HUM-BUZZ-NOISE when you use the fish finder/radar/GPS/Generator or hear your voice on the stereo speakers when you transmit on the radio? Maybe you heard buzzing or humming when you turned on the battery charger/inverter/generator – any of these symptoms indicate you have RFI issues on your boat or RV and you need to stop it or the HUM-BUZZ-NOISE may drive you nuts!
But you don’t have to worry – We got the fix for you – lots of filters, all in a small box, that are easy to install on the wires of your electronic stuff that is bothered by the RFI.
If you have RFI, you need this kit:
