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 to enable side mounting on a tower.


This interlaced yagi gives the best performance at par with any 4-element monoband yagi in its class on 17m and 5-element monoband yagi on 12M.


*** We strongly recommend to analyze and model before mounting any WARC antenna above or below Tribanders or other yagis with separation less than 10 ft. ***
