• C3S-JK - Yagi antenna of 2 elements on each of the 10 m, 15 m and 20 m bands

CS3-JK - Yagi antenna of 2 elements for the 20 m band, two elements for the 15 m band and 2 elements for the 10 m band on a 12 foot (3.66 m) boom.



C3S-JK NEC image


C3S-JK - Two individual elements for each band (10, 15 and 20 m) on a 12 feet (3.66 m) boom.

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

Here are the important changes/features from the classic design ....
1. The feed point for 20 m, 15 m and  10 m 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"(1.83 m).
3. The overall gain and SWR on all bands is consistent & provides excellent performance.
