The JK Quattro is a Quad band Yagi that interlaces 10, 12, 15 & 17 meters on a single boom. This antenna evolved when we combined 2 of our dual-band yagis (1517 & 1012) on to the same boom using the forward stagger method.

 

The Quattro performs as 4 individual mono-banders with 2 separate 50-ohm direct feed-points. The different band elements couples with the other to give additional active elements on 12M & 17M.

 

This antenna has been designed to give a good gain, F/R characteristics on 10, 12,15 & 17. The adjacent band passive elements couple with the active band elements to give a good gain performance on each band for this boom length.  The gain figures alone for this antenna will differentiate it as a leader in its class.

 

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