The JK MegaTri has been designed for Hams looking for a longer boom Tribander while enjoying maximum performance on 20/15/10 comparable and similar in performance to long-boom monobander yagis.
This Tri-Bander's elements follow the same taper schedules and element construction as the Navassa5 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.
