If you have only checked it with the Autek, the newly lengthened and vertical
(at least 80') coax may be picking up commercial broadcast of some sort. At my
place that renders such inaccurate without some kind of rejection for the
offending frequencies.
Using the rig and the regular SWR meter will probably give results not affected
by commercial signals.

Subject: [TowerTalk] I: Force 12 C4 - minimum SWR 2!
Hi om,
today I have mounted my new Force 12 C4 on the tower.
The tower is 40 feet high from the roof, that is about another 40 feet from
the ground.
I have used two coaxial cable 17,5 meters long (about 55 feet), one for 40m
element, another for 20m (and15-10).
I have the resonance on all bands, but the minimum swr on all bands is 2
(two).
Also at 29 mhz swr is very high.
Is this the usual behaviour of this antenna, or there is something wrong?
I have tried it only with my Autek rf analyzer.
I haven't again tried it with the rig.
What do you think?
