Goodness! What are you guys _putting_ on your house-bracketed towers? Why would wind on a thin-member lattice tower and cylindrical-element antennas create more disturbance to framing than wind on a
My 88H400 came with a small PWB that plugged into the Kenwood TS-940, among others. In general, it was sold as a higher-performance (i.e., steeper skirts) replacement for the 500 Hz stock Kenwood hig
Supporting N4DB's premise: Years ago (i.e., long before DX Clusters), as a still-young EE, I was working long hours at GE -- in part, to pay for my ham radio "habit": Collins on the desk and antennas
I weight 165 and I climbed one ONCE to help a friend of mine take his beams off it. I found it horribly uncomfortable (no horizontal surfaces to stand on, and the cross braces cut into your boots and
I don't know about that owl, but *I'm* going to. I have a freebie compass app on my iPhone 3Gs. It's called (believe it or not) "Compass". I've typically only used it in locations where I had no idea
Very interesting, Mike....the testing against known headings that I did on MY iPhone was only AFTER updating it to iOS5 (which was a horrible mistake, but that's a story for a different reflector). _
This is so "not a problem" by using either: a. Four standard 25G sections plus a 25AG4 top section; or b. Five standard 25G sections plus the 1-ft 4-in BAS25 Rohn bearing/accessory shelf section. In
There's no need to cut struts or do anything else that isn't stock Rohn as long as you use one of the two appropriate top sections sold by Rohn. Had them on multiple towers for 25 years. Bud, W2RU __
Interestingly, virtually all of the 2-element commercial HF Yagis I've seen successfully designed and marketed by manufacturers during my time as a ham have been of the Reflector + DE variety. On jus

My old Rohn catalog with drawings of all the various Rohn 25 and 45 top sections has disappeared. I thought I could get the dimensions off the flat plate top section, since those holes are for the TB

This can happen in an _underground_ distribution system, as well. Our home -- originally a seasonal summer camp -- was first electrified in the '50s with an underground single-phase 110-0-110 3-wire
I'm one of those guys up north. Ice and/or wet snow on the linear loading is a disaster; it will move the SWR at the "fair weather" minimum SWR point far enough in either direction to activate the Al
Perhaps you misread my comment, John. In the summer, the minimum SWR point of my 40M2LL is 7.050 MHz. In the winter, minimum SWR may be down around 6.950, depending on the specifics of the ice and sn

Guess I'm not a 'consumer'....to my ears it was better and cleaner-sounding than any other speaker in its price range. And those 'ignorant' professionals who reviewed speakers for the leading audioph
