The JK Mid-Tri (Tribander) has been designed for Hams looking for a Mid level, cost effective but high quality Tribander antenna.
This Tribander elements follow the same taper schedules and element construction as the JK-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.
We have specifically focused on the mounting position of this Mid-Tri Yagi to enable stacking of this antenna on the side of a tower. A good 3 ft spacing between the elements gives the side-mounting option on most towers available in the market today.
If you also need 40 m, check out the JK Mid-Tri-40 !! The 40 m band has its own feed point which enables you to stack a JK Mid-Tri-40 on the top with a JK Mid-Tri on the bottom in a stack (see stack plots below).
The antennas have excellent Gain, F/R and SWR characteristics and are manufactured the same way as our larger Yagis with the same high quality materials and hardware.
