The JK2040 Osprey has great performance characteristics on 20m and 40m. The 27ft active boom 20m Yagi has been optimized for high gain and a good F/R with good SWR performance across the band. On 40m the characteristics of the 3 element Yagi are similar to the JK403 or better.

The 40m element constructions do not need trussing. It's truly an excellent performer and its max F/R characteristics help you hear even the weakest of signals.


The 40m elements can be optimized for your operating bandwidth on 40m.
