JK402-PICCOLO    2 Elements on 40M / 18 Foot Boom


The JK402P (Piccolo) is a 18Ft boom 2 element 40m Yagi that has excellent gain and F/R.  The elements are loaded Capacitively & Inductively which shortens the overall length while still maintaining a good performance across the 40M band.


This antenna is made for the DX'er or Contester that is looking for an antenna to work across the globe with a compact footprint.


It is made with very high quality materials and the best in its class in the market in terms of mechanical construction and electrical performance.


This 40M Yagi has a great performance bandwidth all the way at the CW portion of the band, where the Max performance of this antenna is achieved. It then extends all way in to the upper SSB portion without significant degradation in performance.
