1. [TowerTalk] Rohn 25G Hardware (score: 1)
Author: "Hal Kennedy" <halken@comcast.net>
Date: Mon, 20 Oct 2003 08:44:37 -0400
FWIW, I demonstrated the hard way that the factory supplied Rohn 25G class 5 hardware is very adequate, and stronger than the tower legs. I lost a guy wire on a 25G tower and had it fall over. The to

Very interesting... my expensive failure-modes-and-effects testing began the same way - a failed eyebolt at the bottom end of a guy wire. I have developed a phobia over drop forged eyebolts and turnb

The tips I've read so far are great - and I use them... One more for foam dielectric coax: Do the braid first, then let the assembly cool completely, a LONG time, before doing the center conductor. H

4. [TowerTalk] Weed Whacker Line? (score: 1)
Author: "Hal Kennedy" <halken@comcast.net>
Date: Mon, 12 Sep 2005 22:18:44 -0400
Anyone try weed whacker line for holding up wire antennas? The stuff is tough and cheap - comes in 1,000 ft rolls. Suspect it may not hold up to UV too well however. I plan to put out a few test piec

5. [TowerTalk] Using Clothes Hangers for coax and radial pins/staples (score: 1)
Author: "Hal Kennedy" <halken@comcast.net>

I have often wondered about the electrical effects of steel sod staples. I pulled up a bunch of radials out at K4JA last December - they had been in the ground for two years and the sod staples came

6. [TowerTalk] Parallel openwire lines (score: 1)
Author: "Hal Kennedy" <halken@comcast.net>
Date: Fri, 23 Sep 2005 08:34:56 -0400
Planning on multiple runs of open wire feedline from the antenna field to near the shack. Also setting up for multi-transmitter, so isolation between the feedlines is particularly important. Anyone k

McMaster-Carr, http://www.mcmaster.com/ carries most plastics in rod shape, including delrin. I'm currently making up 1,000 ft of open wire line using 0.25 inch black nylon rod I bought from them. Be

Just bought 5K ft from the Wireman for $0.03 per ft. #22 tinned CU bus wire. No need to use the heavy stuff unless you only plan on one or two radials. Hal N4GG ______________________________________

Author: "Hal Kennedy" <halken@comcast.net>
Date: Mon, 14 Nov 2005 11:15:38 -0500
I guess I have a different take - looking at the pictures and having reviewed these sorts of failures for years in the aerospace industry. The legs (not the welds) have broken at the point where the

The first person who fully understands hydrogen embrittlement (HE) will win a prize of some kind - or at least write a book a few of us metal-geeks will buy. A Google search on the two words will yie

11. [TowerTalk] FW: Feeding a Lazy H (score: 1)
Author: "Hal Kennedy" <halken@comcast.net>
Date: Tue, 14 Oct 2008 10:36:48 -0300
Lazy-H's can be top, center or bottom fed. They can be fed with open wire line (traditional) or coax via a balun. The large H that is here at the moment is bottom fed with OWL and the wires are conne

Author: "Hal Kennedy" <halken@comcast.net>
Date: Thu, 16 Oct 2008 05:39:44 -0800
With all due respect Tom - when center fed, you do not use a twist. When top or bottom fed, you do use a twist. A little discussion on phase and feeding: One reason the Lazy H is such a great antenna

For those who believe they are putting 1/4 wave radials on the ground - it might be important to know/remember that the velocity factor of wire on the ground is approx. 0.5. Quarter wave radials are

Mica domino style caps from WW II onward (also known as transmitting micas) are remarkably stable and efficient at RF (what they were made for). Most of them are Mil-Spec. Most of the date codes on t

I'm with Jim on going smaller rather than larger. My radials are all either #22 tinned copper, which I bought a huge roll of from The Wireman before copper prices went up, or CAT5 wire. I haven't che
