1. [TowerTalk] 40-meter elements (score: 1)
Author: RHealy@mdsroc.com (Healy, Rus)
Date: Thu, 25 Feb 1999 15:17:52 -0500
I'm looking for a known-good taper schedule for full-size 40-meter elements. I'd like something that can handle 100-mi/h winds and small to moderate ice loads. I live in a 70-mi/h wind-speed county t

(I think you mean "below 2:1.") Yes, as a matter of fact, Frank Witt, AI1H, wrote a nice QST article on this about five years ago. I think it was published in the summer or fall of 1993, just after I

4. [TowerTalk] 204BA dimensions for stacking (score: 1)
Author: RHealy@mdsroc.com (Healy, Rus)
Date: Mon, 16 Mar 1998 16:38:35 -0500
I've been fooling with dimensions for stacking Hy-Gain 204BAs. In a two-high stack at 100/50 feet, the F/B really goes to pot compared to what's easily achievable with one antenna. This is Not Good.

5. [TowerTalk] Pier pin v short base in concrete (score: 1)
Author: RHealy@mdsroc.com (Healy, Rus)
Date: Thu, 26 Mar 1998 08:55:47 -0500
If cost is part of the equation, the pier-pin route is much more expensive. Rohn sells the flat base plate and pier pin for somewhere around twice as much as the short base (at least for Rohn 45). --

I'll kick something in here. I have a Mosley TA34 at 103 feet. It has four elements, covers only 20, 15 and 10, and has a 21-foot boom. This is my only antenna for 20 and 10. On the same tower at 48

Date: Mon, 16 Feb 1998 12:02:21 -0500
One thing I left out of my previous post is that the 155CA at 48 feet is at least as good as the TA34 at 103 feet to Europe during the peak hours of the EU opening, but after that and before that the

Dennis, The TA34XL is the heavy-duty boom version of the TA34. The boom is 21 feet long. Each of the four elements has a single trap in each element half. Mosley also makes a 40-meter kit (adds a tr

Actually, this is not necessary, nor is it desirable. In QST, for which I was a staff technical editor for seven years, we stopped doing that when our attorneys determined that there is no reason to

Paul, KB8N, makes some good points about coax leakage. But consider this: 63 dB of coax leakage is an awfully large amount in a hamshack where cables are typically dressed close to each other over so

Hi all, Here's an easy one. I am about to install a 10-ft vertical antenna for 2-meters. If I were to install it at the top of my tower, it would interfere with the lowest rotating antenna only two f

Anybody know whether the Cushcraft 12-4CD has the same element tubing schedule as the 15-4CD or the 10-4CD? And, for that matter, what the element center tubing sizes are for each of these antennas?

I'm about to finally erect the reflector and boom of my 40-2CD, so I thought I'd revisit some modeling topics I looked at several months back. I found something interesting just the other morning (li

As planned, I installed the 40-2CD on Saturday morning with the shortened reflector tips (about 2.57 inches less than the CW dimension listed in the manual). The antenna has exactly the SWR curve (me

I have a Bird 1000D element that has ceased to indicate. I don't believe it suffered any physical trauma--it went unused for quite a while, and now doesn't work. (No, it's not the meter itself). Any

What's your favorite DPDT relay (not remote coax switch) for remotely switching antennas at 1.5 kW at 3.5 MHz? Where do you get 'em and how much do you pay? I'd prefer 12-V dc coils. --73, Rus, NJ2L

Certainly, for high-SWR situations, wider contact spacing is a good thing. I was seeking a source of relays for switching in a 50-ohm system (where the peak voltage never gets very high), which I did
