The 6BA-JK is a Six band / Multiband Yagi that interlaces 10, 12, 15, 17, 20 & 40 meters on a single boom. This antenna is based on the classic Force 12 design and optimized with a single transmission line feed system.

 

This unique design places full size elements along the boom in the same plane and produces amazing 2 element monobander performance on all 6 bands.

 

The 6BA-JK is a direct 50-ohm feedpoint with the other band driven elements connected through a robust transmission line.

 

The optional 6-meter kit places 2-additional elements to make this antenna active on 6 meters - XR7-JK

 

It is manufactured the same way as our bigger Yagis with the same high quality materials and hardware.

 

Built based on the classic Force 12 design.
