The JK1217 Warc antenna was designed as a simple dual band Yagi that performs amazingly on 17m and 12m and on a reasonable sized boom. This single feed point Yagi performs like a champion giving great gain and F/R while keeping SWR low on both 12m and 17m.
This yagi uses the same tapers as the JK-Navassa5 antenna. The Mast mounting position in the center of the boom has a clearance of more than 36 inches (0.91 m) to enable side mounting on a tower.
This interlaced Yagi antennas give the best performance at par with any 4-element monoband Yagi in its class on 17 m and 5-element monoband Yagi on 12 m.
*** We strongly recommend to analyze and model before mounting any WARC antenna above or below Tribanders or other Yagi antennas with separation less than 10 ft. ***
