C-4XL DISCONTINUED
REPLACED BY DELTA 4-XL
4-band Yagi, plus WARC, using tuner, 2 ele 40, 20-15-10
9 elements, Two 50ohm feed lines
|
To enable having gain on all bands from 40 meters through 10 meters on a single boom, the C-3 has been enhanced with a 2 element 40 meter Yagi using 37’ elements to make the C-4XL. The front 40 meter element is the driver and it is placed within the reflector section of the C-3 (similar to the C-4 design). The boom is extended 12’ for placement of the 40 reflector at the core of the C-3. The resulting 30’ boom C-4XL antenna is the answer to covering all of these bands with a single boom. Two feed lines and baluns complete this great package for 5 band coverage (17 & 12 with your tuner).
