15M / 17M Dual-band Yagi

JK1517

2 Elements on 17M
4 Elements on 15M
18 Foot Boom

PriceUS$885.00^**

The JK1517 was designed as a simple dual band yagi that performs amazingly on 17m and 15m 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 15m 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 15M.
