JK Warc
- 2 elements on 30M
- 3 Elements on 17M
- 4 Elements on 12M
- 21 Foot Boom
The JK Warc Antenna has been designed for Hams looking for a simple, cost effective but high quality WARC antenna.
This Warc antenna elements follow the same taper schedules and element construction as the Navassa5 antenna for 17M and 12M elements. The 2-30M elements are identical to the JK302 elements and are Hi-Q coil loaded.
This antenna is very specifically priced and marketed to the segment of the Ham community that wants to put up a Warc Yagi with an outstanding signal and the best quality mechanical build in the marketplace.
This antenna has excellent Gain, F/R and SWR characteristics and is manufactured the same way as our larger Yagis with the same high quality materials and hardware.
This antenna uses a Single Feedpoint for all 3 Warc bands.
