I have assembled a Force 12 EF-240/230 (2 element 30 & 40 Mtr on a common
boom) and have suspended it up 25 feet on a rope between two trees. I am
unable to get the antenna resonant at a frequency that is in either band.
Email to F12 three days ago was not answered.
The best tuning is about 1.25 @ 6.7-6.8 Mhz and quite narrow. On 30 it is
1.5 @ 9.8 Mhz. I do not seem to get the resonant frequency above those
listed. I have tried moving the linier jumpers so they are quite a ways off
what the manual quotes but it does not seem to make much difference. I am
using a MFJ259B on about 35 feet of coax.
Anyone out there had any experience with this antenna and can offer some
suggestions?
Thanks,
Roger, W7VV
