1. [Towertalk] F12 40M antenna near 10-20M antennas (score: 1): Author: ve2dc@rac.ca (Mel Martin); Date: Fri, 26 Apr 2002 16:05:34 -0400; Looking for opinions on this setup. Force 12 claims that their 2 and 3 el 40M beams (240M 340M) can be mounted within 7' of their C31. I modeled the Cal-Av 40M, and various 2el and 3el 40M beams with; /archives//html/Towertalk/2002-04/msg01119.html (8,082 bytes)
2. [Towertalk] F12 40M antenna near 10-20M antennas (score: 1): Author: swca@swbell.net (Mark Beckwith); Date: Fri, 26 Apr 2002 15:42:08 -0500; I have installed 2 Force 12 40M antennas in and amongst antennas on other bands and noticed no reduction in performance of other antennas. In both cases the 15M antenna was 15 or 16 feet above the 40; /archives//html/Towertalk/2002-04/msg01120.html (9,198 bytes)
3. [Towertalk] F12 40M antenna near 10-20M antennas (score: 1): Author: k2av@contesting.com (Guy Olinger, K2AV); Date: Fri, 26 Apr 2002 21:38:31 -0400; Hi Mel, If you have modeled a Cal-Av, you should be able to model the basic form of an F12 N element, with the linear loading folding outward, etc. Since you've done the one model, you've already cro; /archives//html/Towertalk/2002-04/msg01137.html (11,496 bytes)
4. [Towertalk] F12 40M antenna near 10-20M antennas (score: 1): Author: n4zr@contesting.com (Pete Smith); Date: Sat, 27 Apr 2002 02:41:27 -0400; That IS what Force 12 claims, I believe, for their N elements, used with THEIR tribander (the C-31XR). Presumably, that is based an actually having tested the two together. I don't think you can reas; /archives//html/Towertalk/2002-04/msg01157.html (9,121 bytes)
5. [Towertalk] F12 40M antenna near 10-20M antennas (score: 1): Author: nwtncc@iswt.com (James C. Hall, MD); Date: Sat, 27 Apr 2002 14:11:11 -0500; Hi Mel: My experience with this issue mirrors your analysis. I have a F12 4BA at 85' and a MAG 340/620 at 75'. The main thing I noticed is detuning of the 15 meter band ~2 MHz low ! This I am told is; /archives//html/Towertalk/2002-04/msg01170.html (9,112 bytes)
6. [Towertalk] F12 40M antenna near 10-20M antennas (score: 1): Author: k2av@contesting.com (Guy Olinger, K2AV); Date: Sat, 27 Apr 2002 15:26:46 -0400; Hi Jamie, Note that the Mag 340/620 precedes the introduction of the "N" elements. I would guess this antenna has the old design, using support wires to the center of the element as the linear loadin; /archives//html/Towertalk/2002-04/msg01171.html (10,726 bytes)
