Hola Alfredo,
Is this a 40 mts yagi over the C31XR? Maybe is some interaction.
Did you try the C31XR alone in the mast? If not you can try to cross 90
degrees the antennas (ponerlas cruzadas 90 grados)

Asunto: [TowerTalk] Problem With Force12 C31XR
HI
I installed the Force12 C31XR at 75 feet tall and I have a problem in 15M,
it resounds in 20.000Mhz and in 21.000Mhz have 2:5; when I take out one
jumper that connects the 10Mdriver with the 20M it downs the SWR in
21.000Mhz to 1:7 and levels up the SWR in 20M. I don?t know if those jumpers
made the driver longer and that?s why resounds in the 20.000Mhz. I don?t
know what to do because it is by the manual. Any help will be well received!
