The JK2040 Hawk has phenomenal performance characteristics on 20m and 40m. The 38ft 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 JK2040 Eagle. The 40m element constructions do not need trussing unless you live in snow/ice conditions. Itís truly an excellent performer and its max F/R characteristics help you hear even the weakest of signals.
