Bob, I've used this product before, it's called Rust Mort http://www.sjdiscounttools.com/sem69508.html It's basically phosphoric acid, and it comes under other manufacturers and brand names. Try a lo
This topic helped me remember an unusual way of putting a pl259 on RG8 size coax. From K3LR's site: http://www.k3lr.com/engineering/pl259/ Chris KF7P K8RI: > In all my years I have never seen any one
Hi Gerry, I own a T6, and I have friends that own T6's, T8's, and T12's. Tennadyne LPDA's are excellent antennas. They are built to withstand anything you can throw at them. The only negative I can t
http://www.tennadyne.com/specs&prices.htm I have neither of the antennas referenced in previous posts. I did check the Tennadyne site; I could not find weights, turning radius, or other detailed spec
Take a closer look: It looks like there is a cage built around the rotator with (presumably) a thrust bearing at the top. I've seen this in other tube tower installations. Chris KF7P photograph...and
Guys I am doing a club presentation on tower safety, proper installations, and technique at our next club meeting (Utah DX Assn.) I have seen a couple PDF compilations of information regarding towers
Good comments, Jim is right on the money. I would add that 6 ground rods is a good start, but you may want more. I found copper sheet from a local metal recycling place. I bought a 3'x10' sheet and c
Hi Brad, That's the beauty of worm drive winches...they don't require a brake! I have an electric winch on mine, and I drilled a hole through the drum and into the case so I can pin it with a bolt to
Tupperware is for leftovers, not electronics! I can build any size metal enclosure you want. http://www.kf7p.com/KF7P/Metal% 20Werks.html Chris KF7P Those Rubbermaid containers work great! Just be su
Define "large quantities"? I assume you mean more than needed for a top set of guys, or even one entire tower? Chris KF7P same broadcast Drawback it this _____________________________________________
Friends of mine have been using amsteel blue rope on their Jeep winches for several years now; it's good stuff. Easier and safer to handle than wire rope for winching applications, and less chance of
Roger, Do you have arrestors on the bulkhead entrance to the house (center conductor protection), or just the outer conductor grounded? Chris KF7P Even that only sota, kinda, almost works. All of my
Is it just me, or does is seem counterintuitive to have the fall arrest point on the harness in the center of your back? It seems like that would tend to pitch your head forward, making it more likel
Considering how big the tree is at the mounting point (2' ??), the extra weight is nothing more than a big pain in the butt to get it up at that height. 3/8" plate construction is overkill, for sure.
I used my jeep winch to raise my tower off the ground and onto the base. The jeep was parked in the driveway, and I pulled the cable up over the house and hooked it to the top of the tower. I build a
Guys A friend of mine is looking for a good used 70-ish foot crank up, and realizes it may involve a road trip. Let me know if you see any around. We're in Utah. Thanks Chris KF7P ___________________
I thought Marty stated he's using HDPE, that's hi density poly ethylene (not teflon) for the main insulator, and uses teflon (PTFE) for the bolt sleeves and washers. Looks to me that the main compres
I thought I read somewhere that solder breaks down from the UV light. Taping it up or some liquid electrical tape should do the trick. Chris KF7P Y'know, I would have though the solder itself would a
Yeah, that's what I remembered. It's the lead that breaks down. Sorry for the confusion. Chris 1. Solder does not break down due to UV. 2. The lead in lead-tin solder will react with moisture to form
