Yesterday, the wind was calm enough that I decided it would be a good dayswap out my jammed T2X with one that I'd rebuilt. So, I prepare everything and head up my HDBX48 tower (8 ft of mast above the
Thanks to everyone for the replies. I seems I'm not crazy -- I've just never had to be up there when the wasps were doing their thing. Unlike some other comments on here about their docile nature, th
Which bolts? The onse that mount the rotor to the base plate, the ones that hold the rotor housing together, or the ones that hold the mast clamp? Kim Elmore, N5OP ___________________________________
I guess I've been lucky: I check mine occasionally and I haven't found any loose bolts. I'm tempting fate, though, given the responses I've seen here, because I don't use locktite or lock washers. Ne
I'm sure shunt feeding towers has been beaten to death numerous times, but I have a specific question. I'm shunt feeding my 48 ft tower at 1.8 MHz, with various antennas on an 8 ft mast above the fee
With the recently past talk about climbing harnesses and gear, I'm going to ask Santa for some new safety equipment. One way or the other, I want more than I have, which is a safety belt with a lanya
Apparently, my measurements were in the ballpark: I cobbled together an L-network that yields a match. However, in the process I noticed that three of the four bolts that hold my rotator to the plate
I've been trying to determine the feed impedance of a relatively short, shunt-fed tower for 160 m. As configured, the system appears to be resonant at about 9.6 MHz. I borrowed a friend's MFJ-259B an
It's severe storm time in the Southern plains and, while I've taken, and am still taking, steps to protect my shack from lightning damage, I began to wonder... I always disconnect all transmission an
OK, this is what I thought, but wanted to make sure there wasn't something obvious that I'm missing. I don't yet have a nice, grounded, copper-plate bulkhead through which I feed everything, but I'm
Can someone explain how these whole-house surge suppressors are installed? I've looked at illustrations of several and, benighted as I am, I don't see how they are installed. Kim Elmore N5OP ________
Hmmmm... OK... That's an interesting assertion. At what height does a tower cease being a waste of money? Kim Elmore, N5OP _______________________________________________ ____________________________
I was making light of Hardy's incredibly pointless, crass post. Bob has his first tower up and I think that's absolutely fantastic! I got a private reply form someone (not Hardy) who stated simply th
Jam nuts are pretty common devices and are used all the time in things like turnbuckles. Here's a simple test: tighten one nut against another on some threaded rod, screw or bolt. Then, try to turn t
OK, I thought I understood the application, but maybe I don't. I need a picture or a sketch or a diagram to understand what I thought I understood. Besides, I simply slathered the bolts with blue Loc
I dare say that radials are useful under *any* kind of antenna. Anything we can do to decrease ground losses is a Good Thing. A vertical 1/2 wave antenna isn't fed "against" ground as is a 1/4 wave v
This may not be the best place to ask, but I'll give it a shot: I have a vacuum variable capacitor that I use for a shunt-feed L-network at the base of my tower. I tune it using a reversible DC motor
Send it to either Norm's Rotor Service (http://www.rotorservice.com/) or C.A.T.S. rotor service (http://www.rotor-doc.com/). Usually, these things are pretty simple but if you're uncomfortable doing
Links to the actual adapters are very helpful. Where I am in Oklahoma, we have a soft sandstone down about 3-4 ft or so. I've bent 5/8" ground rods trying to drive them through that with a fence-post
I did this once while I was in the dorms (11th floor). I drilled a small hole in a window frame and ran a coupld of hundred feet of small (22 ga) copperweld to a tree. I g8tnded it to whatever I coul
