Many thanks to Kurt, K7NV, for his recent tower load analyses. Verrrry interesting... In his examples of guyed Rohn 45 with the base in concrete, the weakest point was the lower sections, related to
Sorry if this is a dupe, but I never saw it reflected back to me... Many thanks to Kurt, K7NV, for his recent tower load analyses. Verrrry interesting... In his examples of guyed Rohn 45 with the bas
Last summer, I put back in service a CDR TR-44 that hadn't been used in 25 years (for a small 2 meter beam). When I first connected the control box to the rotor in the shack, it didn't work. I replac

Hi Dave - I.C.E. (1-800-ICE-COMM) makes a nice block to attach to the tower. You remove one inch of shield, put in some of the Noalox-type goop, tighten the screws, and you're all set. I.C.E. makes s
The compression of the two metal blocks along with the conductive goop seals it. There is a small section (maybe 1/4 inch) at both edges of the block to accomodate the coax jacket, then it narrows fu

While I've never had the need to run 120 VAC to the tower, I don't understand what the big deal is AS LONG AS IT'S DONE RIGHT. Meaning, have an electrician do it, or follow the NEC yourself. I have a
Hi all - Happy holidays. I thought I'd take advantage of a sunny, not so cold day to replace the intermittent direction pot in my TIC Ringrotor. As with everything else related to this device, it was
I'm thinking about putting up a second Beverage this season, and wonder what everyone does to switch them. I'm thinking about using an Ameritron RCS-4 to switch on the high impedance side of the 9:1

Can someone explain to me why the rebar WITHIN the concrete doesn't rust? Concrete always retains moisutre and absords it from surrounding soil, doesn't it? Rust is oxidation. Being underground, whet
Looking for some construction advice: I picked up a made-for outdoors metallic junction box from the Elec. Dept. at Home Depot. In it, I plan on installing a Beverage transformer with some relays to
That reminds me - serious question now (really!) Would it be harmful (to the tree) to put a ground rod (copper or galv.) within a few feet of the base of a tree? Any potential toxicity from the metal
Reminds me of the time in college physics when the prof. was teaching the right hand rule. Some wise-ass raised his hand and asked "how do I know which is my right hand?" The prof answered "Hold your
Hi Brian - I had a local metal shop cut 3 pieces of galvanzied sheet metal (14 ga, I think) 18 inches by 5 ft. I then attached 2 pieces of aluminum "angle iron" back to back, to permit the metal shee
