Kelly There are a number of moisture barriers on the market. Aluminum-based types are NoAlox or Penatrox. We sell a copper-based product which is part of our model CCK (Copper Cleaning Kit). A moistu

Dan First off, it's a 150' tower in parallel with 135 feet of coax. Insofar as #6 vs strap. There are three factors: surface area [the grounding system's surface area must equal or, preferably, excee

Exothermic welding is the best method for interconnecting dissimilar metals. Basically it heats everything up to a very high temperature very quickly and so "fuses" the metals together. Basically thi

While probably too costly for the ham market in the quantities needed, Times Microwave Systems (TMS) makes impedance transformation cables without transformers or VSWR sacrifices. TMS 358 Hall Ave PO

Rod The major concern I'd have with the aluminum is its thinness insofar as carrying "boocoo" current was concerned. It's half the thickness of our copper strap. You probably don't need 6"-wide coppe

Lynn All things being equal, a truly guyed tower (i.e. conductive and uninsulated) will have a voltage gradient between top and bottom of approximately 1/3rd that of a tower which is either freestand

Alfred While the Cushcraft devices DO work, the PolyPhasers are demonstrably better protection. Both devices, in fact any brand of protector, are only as good as the lightning ground system provided.

Post #1 The rig will probably suffer damage. The power ground is just one ground rod which is insufficient to get all that energy into the earth. A radial system, as described in our catalog (Appendi

Hiya, Jay, I'm at work, so I can go a bit further with this thread. Generally, corrosion is a problem when the atomic potential (nobility) exceeds +/- 0.3 Volts. The lower this value, the longer corr

Some myths die hard. The ARRL still insists that Ufer grounds are a no-no (and if you look into it, you'll realize that failure to utilize a Ufer ground could cause the concrete to crack). If a Ufer
