TT: Today I mixed a solution of 1 part household bleach to two parts hot water and sloshed this over the mildew on top of my tower's concrete base. With just a bit of encouragement from a plastic kit
David: I, too, was a novice at installing self-supporting towers when I built my Trylon in 2001. I had helped a couple of friends construct guyed Rohns years ago, though. Plus I had worked as a brick
Bill: You might want to try a shunt wire for 160M on another tower face, but space it more than a just few inches from the tower. I'd suggest a couple of feet. Most shunt wire designs I've read here
Michael: I have a D40 up at 78 feet. I followed the instructions to set the resonant point at 7.090 MHz. When I got the thing up on the mast, low and behold, it was right on the money. Just follow th
TT: I agree with Jim about the usefulness of a flat plate on which to stand on the tower top. The Trylon Titan series of towers (mine is a T-500-64) has such a flat plate a few inches below the top,
Roger: The sloping front yard complicates your project a bit. I can offer a few suggestions, though: o Check with the concrete plant. Maybe they can send someone to scope out the site in advance. If
Jerry: I read in one of my source books that it's about 4000 pounds per cuyd. (!), depending on the mix. But before you swear by this figure, allow me to verify the source. I'll post it here. 73 de G
Jerry et al: I checked my copy of Pocket Ref, Second Edition (Sequoia Publishing) for the weight of concrete. For limestone aggregate, Portland cement concrete, the weight is listed as 3996 pounds pe
Ron: The Trylon web site (www.trylon.com) has info on such side-mount brackets on the accessory page. I tried to copy and paste the URL for the page for you but the site has some problems right now.
TT: I did a tiny bit of maintenance on the shunt-feed for my Trylon this afternoon and thought I'd pass along this note, mainly as a reminder to do some tower maintenance yourselves. I took a break f
TT: As part of my Trylon tower maintenance this year I want to scrub the concrete base to remove the green mildew, or whatever it is, that has accumulated on the surface of the concrete. FYI, the tow
probably BIll: Don't be in a hurry to get your coaxes connected and the antennas operating. Take this opportunity for psychosomatic QRM complaints to come and go. That is, when you get your first com
TT: Thanks for your suggestions on cleaning mildew off my tower's concrete base. Here are the essential recommendations I received: o Power-wash (vast majority of you folks recommended this approach)
Van: A local (Washngton, DC) ham uses the C-shape for his vertical wire antenna on 160M and claims he does pretty well with it. He cut the dipole for 160M as usual. The center section he hung vertica
TT: I used the staggered method when laying out the holes on my SPG plate. I also used the Wireman's feed-through bushings and large bushing nuts. This combination provided the connection to the SPG
Byron: If you can lay yours hands on one, the July 2001 issue of CQ mag has an article by Dick Stroud W9SR on his Large, Remotely-tuned Loop for HF DX. It's a 160M full-wavelength horizontal loop and
TT: This phenonmenon, known in the electric utility industry as step potential, is, indeed, real and potentially lethal. In designing our electrical substations and power plants, we electrical engine
Tony: I used this site http://home.att.net/~katzmann/ to get to a freeware program that printed out a Great Circle map centered on my QTH (well, Washington, DC anyway.) No prefixes listed. Instead, I
Rob: I agree with using NoAlOx from Home Despot. I bought a small bottle that had a brush built into the lid. And don't heavily lather the stuff onto any joints. Thoroughly clean the joint areas (ID
Michael: I bought my CM from Special Metals in Oklahoma City in 2001. Check out my and Jerry W5KP's comments at http://lists.contesting.com/_towertalk/2002-February/045005.html . The 100+ pound stick
