C3S-JK - 2 Elements on 20M / 2 Elements on 15M / 2 Elements on 10M / 12 Foot Boom

Re-Designed, Optimized & Improved from the Classic Force 12 design

 

The C3S-JK (Tribander) has been re-designed, optimized & Improved from the very popular Force 12 Tribander

 

Here are the important changes/features from the classic design ....

 

1. The feed point for 20M, 15M & 10M are connected using a transmission line, the same way as the JK-MidTri & JK-BigTri.

 

2. The mast mount position is right at the center of the antenna at 72".

 

3. The overall gain and swr on all bands is consistent & provides excellent performance.
