Thanks for mentioning that locking device. I didn't know they existed. I always thought the APP did not have enough retention force when mated and I assume these locking devices should solve that pro
I've had the same experience as Roger. Decades ago I started to convert to N-series connectors, but started having problems with the non-captive pins pulling out in cold weather. I have gone back to
Weller also makes one like that. I have one and it works great on top of the tower, though I am trying to move toward other kinds connections up there whenever possible. 73, Bob - W3YY There is one.
Bob WW4T - I can't directly answer your question about JK antenna offerings and not sure from your post whether you want 3 or 5 band performance, but the Bencher Skyhawk seems to be a FB tribander on
I only hope this property is acquired by a contester who can use it to its full potential and maintain it. I'm too old for that, HI! 73, Bob - W3YY The link that was previously posted got busted sinc
The other tuner worked and your new MFJ didn't. Sounds like whatever you are trying to match is outside the range of the MFJ, but OK with the other tuner you put in line. Without further data, that's
But I bet KQRS had their "on the air" light outside the glass, HI. Sorry to be totally off topic, but for those of you who don't know, Herb was a pioneer FM DJ in the 1960's at Minneapolis FM station
My 4-el SteppIR has been up for 11-1/2 years without any need to take it down. 73, Bob - W3YY If you are a member of the SteppIR Yahoo group you would get the idea. Unless things have changed and que
Check the tower specs, but I would think that 75ft of guyed Rohn 45 would be more than sufficient. Rohn 55 seems to be overkill to me. Build the DB36 on the ground and tram it up or get a crane. I'm
I've used the small Kevlar (about an 1/8" in diameter) cord for boom and element trusses and it works great. But maybe not so great for supporting the ends of inverted vees. The last 80-m inverted ve
Two towers here - 120ft Rohn 45 and 100ft Rohn 25, both built with the original hardware supplied by Rohn. No problems with the hardware here during installation or in the 35 years since. But, if you
I haven't reviewed all the background info, but.. I've been using 6700 Phillystran for years on both a 100 and 120ft tower with big grips. So I don't understand the current discussion. See the link b
If they still offer it, also consider the two element Force 12 Magnum 240N. Unlike most shorty 40's, it covers both the CW and phone segments of the band, is about 80% full size, but is relatively li
The latest posts about grounding, and finally some free time here, prompt me to ask the following question. Given lightning's desire to find the quickest way to ground, why doesn't it expend itself i
Dan - If this helps, see my Phillystran installation details at http://www.w3yy.com/Phillystran.htm Be sure to click on the "For a step-by-step pictorial Click Here", to see the assembly details. And
HI Jim - What's the name of the glue you describe below? 73, Bob - W3YY A good 2 part Epoxy. If you do a good job preparing the surfaces, the metal will fail before the epoxy. (but I'm thinking about
This is not one of the ones you suggested, both of which are probably both wonderful, but I've used a number of the Ameritron RCS-8V switches over the years and they've stood the test of time and are
I've also had excellent results with a G-2800DXA rotating a 2-el Force 12 Magnum 240N 40M beam at 120ft and a G-1000DXA rotating a 4-el SteppIR at 100ft. Over a decade with no problems. I use Green H
No, you haven't paid for the source code. You paid to use the program. I know of no agreement to open-sourcing the code in any agreement between N6BV and the ARRL. As hams, we've been blessed to have
My 4-element SteppIR has been up for 13 years at 100ft. I'm sure we had have some 60 mph wind gusts in that period. No problems until recently when one of the element support tubes broke off at the E
