I'll guess that it might bleed off static electricity, like the megohm resistor in my ESD wrist band... 73 de Dick, K6KR Anyone familiar with the Ameritron RCS-10 remote antenna coax switch? I am int
I'd encourage you to get on the air with whatever you can and enjoy the contacts you can make. All of us have antennas that are "less than perfection". If your less-than-perfect 80 meter vertical mak
I used a set of coax standoff arms for my 89' crankup. I have an RG-8 sized feedline for each of 6 antennas plus a rotator cable and a control cable for an 80 meter switch box. I taped the cable bund
Can anyone recommend a source for the small stainless steel saddle clamps? Dick, K6KR --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting.com] On Behalf O
I'd assume that there are capacitors and inductors inside. Caps could blow? W9KNI would know for sure. Dick, K6KR In the middle of SS this afternoon, started to get very high swr on transmit, althoug
There is an article titled "Broad Band 80 meter antenna" by Allan Harbach, WA4DRU from the December 1980 issue of QST that can be found in the ARRL members area. I think this is the article duplicate
I've heard that tennis ball launchers are all the rage. http://www.antennalaunchers.com/antlaunching.html is one site that describes these beasts. Safety is the main issue here. Dick, K6KR Hello, I k
I have coax arms that just guide the coax, the coax isn't fastened except at the top coax arm (with Kellum grips). When the tower comes down, the coax gathers on the ground. I'm always out there to c
I've always called them "reversible ratchet wrenches", and a Google search using that name came up with what I'd expect. Dick Howdy, TowerTalkians -- What is the name of the closed-end, single sized
If you're not hot-switching does it change the answer to what the issue is? Dick, K6KR --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting.com] On Behalf
It depends on what you choose to break should the turning force on the mast exceed the strength of the weakest element. Something has to be the first thing to "give". What would you like that to be?
If you have so much of it, maybe don't separate it, just run a pair for each radial... Dick I have a half kilometer spool of military field telephone wire. It's not twisted pair. I want to separate t
I think many of us tune antennas at or near ground, and then put them up, and find that the resonant frequency changes with height. I write down the values on the ground and at altitude, then bring i
I'd suggest that the concrete base be finished in such a way that water runs off the base and away from the bolts holding up the tower. Either a high center or a slope. I'm not sufficiently trained t
antenna. The text claims that the transmitting site is somewhere else, already scrapped. I've seen and marveled at these pictures before. But if this was just the receiving site... What did the tran
That's what I did. I had several lines (6 coax, rotator cable, and a light 4 conductor cable). I added a brace to help support the top coax standoff. All the weight of the coax is supported by that s
I'd like to rotate a 45' pushup mast (a Rohn H50) from the base. What sort of guy rings exist that will slip smoothly to avoid winding up the guys? I'd also like to use Dacron rope for the guys, but
I'm contemplating my first guyed tower with side-mounted antennas. What sorts of planning tools do people use to determine if the antennas of various turning radii will clear guy wires? In my plannin
I didn't tie mine off except at the top. The top section has Kellum grips supporting the coax. The coax slips through the lower stand offs and as I lower the tower, I coil the coax bundle near the ba
I'm preparing to install my first HyTower. I'd like to be able to use the antenna on the low end of 80 meters, and from the HyTower manual it appears that I need to switch in a loading coil that is d
