G5RV/ZS6BKW Antennas

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.

Solar Charge Controller RFI Kit - 3 I/O Ports
Product Details

Purpose. Simple, Effective RFI Kit consisting of 3 Solar Noise Filters (Mix 75) with 1/2" ID, for use on 3 Input/output ports such as Solar Panel Array input, Battery and Excess Load ports. Noise filters suppress noise and RFI at typical frequencies generated in solar charge controllers.

This kit is designed to choke common mode currents going into or exiting from your charge controller and they help keep common mode current out of the power line (or into your radio through the battery) which could cause interference to other devices connected to the same power line if not suppressed.

THE RFI KIT FILTERS ONLY SUPPRESS COMMON MODE CURRENT (SIGNALS) THAT ARE COMMON TO ALL WIRES IN THE CABLE, AND DOES NOT EFFECT INDIVIDUAL DIFFERENTIAL SIGNALS ON EACH WIRE. THE FILTERS HAVE NO EFFECT ON THE NORMAL SIGNALS CARRIED WITHIN THE CABLE.

If you use an inverter and experience RFI noise use additional mix 75 ferrite filters on the input and output of the inverter to help suppress this noise.Install both positive and negative wires through the same filter.


 

Here is the Coax Noise Filter used to suppress coax common mode currents (works for all type of antennas)
