Hi Tom, interesting comments on grounding. I've got a few questions about your technique. thanks, Dave AB0GJ <snip> What good does buring the cables do? Tom, what do you mean by "add a single loop of
Hello, I've got a tower with a triband yagi at 35'. It is located 50' from a 10kv power line with the antenna at about the same height as the power line. I'm getting real bad static on 15m and am won
<snip> Absolutely true, but try to bend a solid shield Both of these effects are included in the inductance formula I gave. The "bunching" you describe, is an artifact of the self inductance of the s
Not necessarily. Most solid state amplifiers can operate into a 2:1 vswr or less with no problems. This means no tuning for me. I doubt it. Considering the fact that most tube amps have to be tuned
Or in dc applications...Actually, some powdered iron and especially ferrite cores are pretty easy to saturate under certain conditions, such as when used with large dc currents. For instance when us
Boy, I would think you'd want the ground grid to be as deep as reasonable because this grid may be dissapating all or part of the energy from a lightning strike. When I worked as an electrician in Wy
I had the same question about galvanized vs. stainless when I made my own crank-up system for my aluminum tilt-over tower. What I found is that galvanized is about 30% stronger than stainless, but st
Sorry, this may not be so relevent to this reflector, but I just found an abandoned satellite tracking ground station that I'm told I can have if I can dismantle it and haul it away. It's a Rohn 25 t
Can anyone recommend a good way of bringing antenna, rotor, and miscellaneous cables into the shack? My requirements are the following: 1. Cables must come through the wall (not an open window) and a
Shouldn't this be prevented from happening if a ground wire (or better yet, low inductance flat ground strap) is run from the tower base along side (and burried below) the antenna cables and is termi
I can Tom. Its a pretty well known fact in the industry that ribbon conductors have lower inductance than round wires of the same cross sectional area. In fact, the inductance of a ribbon of a given
