1. [TowerTalk] trying to ID a tower and determine foundation requirements (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Tue, 15 Jul 2008 23:31:09 -0400; Hello, My name is Blair, callsign NP2F. I bought a used tower, it appears to be in good condition - just has some slight surface rust on the base. It is 39' tall, self-supporting, galvanized steel, t; /archives//html/Towertalk/2008-07/msg00425.html (7,694 bytes)
2. [TowerTalk] distance between monobanders (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Mon, 04 Aug 2008 11:46:44 -0400; Hi all, I have a 4-element 10 meter beam for my tower. I also want to put up a 6-meter beam, and possibly one for 2 meters as well - all on the same mast. I know there are a lot of experienced amateu; /archives//html/Towertalk/2008-08/msg00073.html (6,920 bytes)
3. [TowerTalk] converting a 10 meter monobander to 20 (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Thu, 18 Sep 2008 15:52:29 -0400; Hello towertalk ops! I have a Cushcraft 10-4CD 4-element monobander. Given current conditions on 10, I'm thinking about modifying it to work on 20 meters instead. I figure adding loading coils into e; /archives//html/Towertalk/2008-09/msg00337.html (7,412 bytes)
4. [TowerTalk] wire antenna question (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Sun, 09 Nov 2008 10:07:53 -0500; Hello antenna gurus, I have a question regarding wire dipoles that's been bothering me. I'm sure someone on towertalk can help. Here it is: When I put up dipoles, whether they be "straight" or invert; /archives//html/Towertalk/2008-11/msg00214.html (7,875 bytes)
5. Re: [TowerTalk] wire antenna question (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Thu, 13 Nov 2008 11:59:24 -0500; Thanks to everyone who responded. I feel much better about what I've been doing. Terry, yours made such perfect sense, I thought I should have known it already!

6. Re: [TowerTalk] wire antenna question (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Thu, 13 Nov 2008 14:05:46 -0500; Hi Gerald, I guess this is something I'm not clear on. By my calculations, an antenna having an impedance of 40+j10 or 40-j10 would have 41.23 ohms. If SWR is the ratio of the two impedances (coax an; /archives//html/Towertalk/2008-11/msg00345.html (15,636 bytes)
7. Re: [TowerTalk] wire antenna question (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Sat, 15 Nov 2008 16:45:40 -0500; Well, I suppose my understanding was not quite right. I had assumed that, if you could get the load impedance to a value of 50 ohms (when using 50-ohm coax), you would get a 1:1 SWR. I thought this i; /archives//html/Towertalk/2008-11/msg00383.html (9,840 bytes)
8. Re: [TowerTalk] Resonance is over rated (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Fri, 07 Aug 2009 20:10:26 -0400; Hi everyone, Wouldn't a better definition of a resonant circuit be a circuit that has reactance, but where the capacitive reactance is equal to the inductive reactance? That would exclude a purely re; /archives//html/Towertalk/2009-08/msg00120.html (12,380 bytes)

Re: [TowerTalk] Element straightness (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Tue, 10 Nov 2009 10:29:05 -0500; Hi Bob, I put up a used Cushcraft 10-4CD beam a little over a year ago. After getting it assembled and before putting it up, I had it laying in the back yard. My daughter's dog got it's line tangled; /archives//html/Towertalk/2009-11/msg00176.html (10,160 bytes)
10. [TowerTalk] dipole configuration (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Fri, 04 Dec 2009 08:10:41 -0500; Hello towertalk group, I'm getting set to put up a wire dipole for 160 meters. I'm considering 2 options, and I wanted to hear which one you guys think might be better. The feed point will be about 3; /archives//html/Towertalk/2009-12/msg00024.html (7,882 bytes)

The double-L looks interesting, but I'm not sure the vertical height I have will allow me to use it. My tower is only 40 feet tall, and, to make th; /archives//html/Towertalk/2009-12/msg00053.html (12,042 bytes)

Re: [TowerTalk] Low SWR (score: 1): Author: Blair S Balden <blair.balden@wmich.edu>; Date: Mon, 01 Feb 2010 09:30:47 -0500; Hi Andy, These values are important because SWR is a measure of how well the input impedance of your antenna system matches the output impedance of your xmtr/feedline.
