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

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

Author: thorh@worldnet.att.net (Thor Hallen)
Date: Fri, 24 Aug 2001 11:40:30 -0700
The G5RV is a 100' dipole with with a balanced transmission line matching section that results in a moderate SWR on most HF bands that is within the capture range of most automatic antenna tuners. At

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

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

Author: thorh@worldnet.att.net (Thor Hallen)
Date: Fri, 22 Jun 2001 18:09:26 -0700
The log periodic design in the ARRL Antenna Handbook is not one that I would recommend. I have made comparisons with another local ham working common DX stations simultaneously and concluded that the

Joe: My C3SS is pretty much useless on 17 meters with a VSWR of approximately 10:1. 12 meters is within the capture range of my automatic antenna tuner with a VSWR of approximately 4:1. The design fr

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

Stephanie: I would be far more interested in the customer support reputation of the companies than small differences in specifications that have no practical impact on the antenna's effectiveness. In

Bill: The "Carolina Windom" is an Off Center Fed dipole rather than a true Windom as both are described in the ARRL Antenna Book. By feeding off center, a reasonably low SWR in the range of 2 to 4 ca

Ed: Yes, there is radiation off the coax feeding the antenna if a balun is not used at the feed point because the off center drive point creates an unbalanced load unlike a center fed dipole. Notwith

Joao: I used a MA5B for about 6 months and replaced it with a Force 12 C3SS. As near as I can tell, the MA5B performed as well as the C3SS and is much smaller. The MA5B has a trapped dipole element f

Both sides of this controversy may have valid points. Cushcraft apparently tried to provide good support to hams in the past but was bought out a few years ago by new management that is arrogant and

Ted: The G5RV will be slightly more directional toward the broadside on 40 meters than a half wave dipole by a couple of dBs. A parallel 40/75 meter dipole will allow you to achieve low SWR on both b
