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.

ID-B (in/mm): 1.4/35.6
OD-A (in/mm): 2.4/61
Height-C (in/mm): 5/12.7

Bothered by RFI/EMI from your aquarium pumps or heaters? If so use this filter on the AC power cord of each heater/pump to suppress the interference. Fits standard 120VAC AC plug

(2.4″ OD, 1.4″ ID hole), RFI Noise Suppression Range: 150 KHz-10 MHz, MIx 75

Excellent for standard 2 or 3 wire AC cables or multiple cables – use multiple cores in series for higher RFI suppression. Also useful when you need high turns count for high choking with large cable - works on all 120/240 and lower AC voltages.

Note: Wire shown for application purpose, NOT included with purchase.

If you want the AC chord with standardized AC plug, preassembled on the ferrite filter, see part# AC-CHOKE-6


 

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