The JK Big-Tri has been designed for Hams looking for a slightly longer boom Tribander while enjoying maximum performance on 20/15/10. It is ideal to install under the JK-Mid-Tri-40 antenna to make a stack for 10, 15 and 20 m and having a superb 40 m antenna within. This Tri-Bander's elements follow the same taper schedules and element construction as the JK-Navassa-5 antenna.
This antenna is very specifically priced and marketed to the segment of the Ham community that wants to put up a 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.
