Fabio, The answer to your question depends on whether the element has drain holes or not. If it has drain holes on the bottoms of the capacitor tubes, it will dry out very quickly. If it doesn't have

3. [TowerTalk] 160m - Sloper vs. Inverted L? (score: 1)
Author: "Larry Schimelpfenig" <k7sv@comcast.net>
Date: Sun, 13 May 2007 07:57:38 -0400
Will, I have to agree with Roger K8RI's comments. Some folks have had great luck with a half sloper, others haven't. On the other hand it appears that performance of an inverted L is quite consistent

Barry, I swung a KT36XA and a 2El KLM 40 with a T2X for 12 years or so. The only time I had a problem is when I decided to reposition the antennas duirng a wind storm. As soon as I released the brake

Some 30 years ago I had a 4BTV strapped to the chimney of the two story farmhouse I lived in. The base of the vertial was at about 25 feet. I had three quarter wave radials on each band laying on the

I don't know if the amateur radio vendors such as Texas Towers, HRO, AES etc. are any more apt to stock larger more expensive antennas than the manufacturers, but you might ask. Another fine antenna

Jeff, I bought a used one 12 years ago and had it up at the home qth here for 11 years, then moved it out to the NR4M contesting qth. Never had a problem with it. While it was set for cw, running low

While the picture is not up close enough to see much detail, between the silhouette and the sat view I'd bet a dollar to a donut that it's the HyGain 4 through 30 log. This is the Telex/HyGain LP-100

I don't think you would be going wrong with either choice. While I haven't used one, I did help K4FJ put his Skyhawks up. They appear to be well built, and Steve is very pleased with how they play.

I had interaction problems between my 2 el KLM 40 and KT36XA spaced 8 feet apart. Moving the booms 90 degrees apart resolved the problem. Based on Bill's comments it looks like 10 feet will probably

Date: Mon, 19 Nov 2007 07:11:07 -0500
At NR4M we haven't gotten around to getting a more permanent 160M antenna in place, so we've been using a sloping wire vertical or most recently a TEE. There is a catenary between the 120 foot 15M to

Dave, I appreciate the input. I started with a convential swr bridge and that's what led me to look at the thing with the analyzer. However, it seems that I was leading myself astray last night. NR4M

I certainly agree with what Tony has said. Seeing the severity of the situation, my first inkling is to think it's probably a problem with one of the feed log cells. Bill, if you have both antennas o

Date: Fri, 29 Feb 2008 18:37:02 -0500
Rob, I've spent a lot of time on 25, 45, 55 and AB105. I find working on Rohn tower to be much easier than working on 105 largely due to the horizontal braces on all three sides of the Rohn all the w

Rob, If you contemplate the need to stand on top of the tower, you certainly want to go with the flat AG4. You'll need a thrust bearing with the AG4 while it's not necessary with the AG2. Something I

Paul, While the combination of antennas you're dealing with is a bit unique, the experince I've had with my KT34XA and 40M antennas may be helpful. It looks like the Comet antenna covers 40 through 1
