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.

Home Theater System RFI Kit for AC Powered Sub-Woofers Only - 5 filters
Product Details
MPN: RFI-HTS-SW
Type: NEW
Country/Region of Manufacture: USA
Filter Power Rating (PEP watts): not applicable
RFI Suppression Range (MHz): 1-300 MHz

This sub-woofer RFi kit is specifically designed to suppress audio interference triggered by Radio Frequency Interference problems from AM, FM, CB and Ham radio stations AND to minimize the interference to nearby electronics caused by a sub-woofer without magnetic shielding (Velodyne, Hartley, Hsu, etc). The ferrite filters are selected to suppress RFI from 1 to 300 MHz. The filters are easy to install, don’t require modification of the protected equipment and work in almost all cases.

What is included in the kit?

The RFI-HTS-SW kit contains a a ring filter for the AC power cord to the sub-woofer and 4 snap-on filters for the speaker wires (either for audio pass through to main speakers or direct line out to the sub-woofer).

Tech Note: This kit is INCLUDED in the full home theater RFI Kit (part #RFI-HTS) and you do not have to purchase a separate RFI kit for the sub-woofer.
