[Towertalk] Antenna choices in a restricted neighborhood (score: 1): Author: thorh@worldnet.att.net (Thor Hallen); Date: Sun, 31 Mar 2002 20:55:54 -0800; Bill: I assume that your primary interest is DX from your post. Since towers or out of the question, it would seem that you are limited to verticals. You can improve the efficiency of a single vertic; /archives//html/Towertalk/2002-03/msg00008.html (9,722 bytes)

4. [TowerTalk] 80m dipole on a small lot (score: 1): Author: thorh@worldnet.att.net (Thor Hallen); Date: Tue, 27 Nov 2001 11:05:16 -0800; Jerry: I would put up a G5RV rather than a 80 meter dipole. The G5RV is only 100 feet long and can be used on most of the HF bands in addition to 80 meters. You can mount the center on your tower and; /archives//html/Towertalk/2001-11/msg00536.html (10,025 bytes)

[TowerTalk] Tennadyne LPDA Balun Location (score: 1): Author: thorh@worldnet.att.net (Thor Hallen); Date: Sun, 8 Jul 2001 06:18:20 -0700; W8JI correctly observes that the Tennadyne balun is not located in the ideal location. This has been noted by others and Chuck at Tennadyne did not argue the point when I discussed it with him. His e; /archives//html/Towertalk/2001-07/msg00115.html (8,802 bytes)
7. [TowerTalk] log periodic antennas (score: 1): Author: thorh@worldnet.att.net (Thor Hallen); Date: Fri, 22 Jun 2001 06:56:16 -0700; I recently replaced a Force 12 C3SS with a Tennadyne T6 log periodic to be able to work 17 meters. The T6 has consistent good performance from 14 to 30 MHz with VSWR of 2:1 or less. The tradeoff with; /archives//html/Towertalk/2001-06/msg00521.html (9,345 bytes)

[TowerTalk] C3 on WARC bands (score: 1): Author: thorh@worldnet.att.net (Thor Hallen); Date: Thu, 17 May 2001 07:00:49 -0700; Apparently the C3 and especially the C3E do much better on the WARC bands than the C3SS. The C3SS linear loading causes very high SWR on 17 meters. I am in the process of replacing my C3SS with a Ten; /archives//html/Towertalk/2001-05/msg00383.html (9,985 bytes)
