The JK Antennas Navassa-5 is a five band / Multiband Yagi that interlaces 10, 12, 15, 17 & 20 meters on a single boom. This antenna is based on a collaborative design by E73M Daniel Horvat.
This unique design places full size elements along the boom in the same plane and produces amazing 2 element monobander performance on all 5 bands.
The Navassa-5 is a direct 50-ohm feedpoint with the other band driven elements connected through a robust transmission line.
This antenna has been designed to give the everyday ham-radio operator an excellent antenna to operate on all 5 bands. The short boom length was taken into account to keep the antenna compact and the installation simple.
The optional 6-meter kit places 2-additional elements to make this antenna active on 6 meters.
It is manufactured the same way as our bigger Yagis with the same high quality materials and hardware.
