1. [TowerTalk] Force12 EF-320 (score: 1): Author: wp3c via TowerTalk <towertalk@contesting.com>; Date: Sun, 07 Aug 2016 10:00:43 -0400; Hi I put a Force 12 EF-315 and a EF-320. The one for 15M (EF-315) is 1:1 but the one for 20M (EF-320) I'm having SWR high. Did someone here that have some knowledge about this antenna and could brin; /archives//html/Towertalk/2016-08/msg00073.html (6,867 bytes)

However, since your post was unanswered and lost in the measuring coax loss within .001dB thread I will try to help. I believe that Force12 monobanders are OW; /archives//html/Towertalk/2016-08/msg00084.html (7,594 bytes)

If the SWR is unchanged with the jumper the issue is; /archives//html/Towertalk/2016-08/msg00085.html (9,183 bytes)

I have no experience with the EF-320 but do on many of there other antenna models. So are OWA 50 ohm direct feed some are not....

On 20m, the C31XR uses a 5T 2.0" 0.125" hard drawn copper coil a; /archives//html/Towertalk/2016-08/msg00091.html (11,846 bytes)
