2 Elements on 10M / 2 Element on 12M / 2 Elements on 15M / 2 Elements on 17M / 2 Elements on 20M / 12ft Boom
JK Antennas Navassa-5 Multi-Band Yagis interlace full-size 20, 17, 15, 12 and 10-meter elements on a single 12 ft. boom with a rugged 2 in. diameter. Named after the Navassa Island DXpedition, these antennas are based on a collaborative design effort by Daniel Horvat, E73M/N4EXA and JK Antennas.
JK’s unique design places full-size elements on a single boom and produces amazing 2-element mono-band performance on all 5 high bands! This results in producing good gain and great SWR bandwidth on all 5 bands. An optional 6-meter kit adds 2-more elements to make these antennas work on the 50 MHz Magic Band.

These antennas have been designed to give the ham radio operator an excellent antenna for operation on all 5 high bands with automatic band switching and a single feed line. The short boom length was employed to keep the antenna compact and the installation simple. Navassa-5 antennas use direct 50-ohm coaxial feed with the all driven elements connected by a robust metal strap balanced transmission line. A high-quality 1:1 current balun is required. The COMTEK COM-BAL-11150DT is recommended for full power handling and best performance.
Like all JK Antennas, Navassa-5 beams are manufactured with high quality materials and hardware; like their larger low-band Yagis. A 1/4 in. (6mm) thick mast plate and all mounting hardware is included with these antennas.
When you think about working DX on the WARC and Classic High Bands using a high-performance Yagi, think about JK Antennas Navassa-5 Multi-Band Yagis.
