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.
