The JK1217 Junior WARC antenna was designed as a simple dual band yagi that performs amazingly on 17m and 12m and on a smaller 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 interlaced yagi gives the best performance at par with any 3-element monoband yagi in its class on 17m and 4-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. ***
