Bill-- That is WHAT it is -- a single-point ground. That doesn't mean that there cannot be other grounds or that there cannot be two single-point grounds, or even more, in a system. It is EASY to ha
Hi, Jerry-- Not only did you NOT use the term "single-point ground" neither you nor Bill have made any suggestion for a more accurate term that is simple, while remaining descriptive. I would sugges
Bill-- You have PRECISELY made my point for me. They ALL have one concept in common. SINGLE POINT GROUND! Single point ground is the superset of all of the subsets including the three you have liste
But the correct superset contains the specific subset by definition. So the superset term is always correct -- even if a subset term is more precise and illustrative of a specific point. But the conv
Securing Coax to a tower. Since hams tend to be experimenters it is nice to select a method that can be reused if more cables are added in the future -- which gives an advantage to using TW wire for
Jeff-- There is a big difference between a one-time (or limited number of bends) bending radius and repetitive flexing. I would use something like Ultra-Flex for repetitive bending applications aroun
Steve-- Resonance is not defined as lowest VSWR! It is the frequency where the reactance goes to ZERO and may not be the lowest VSWR. So the problem you are having to determine the resonant point ma
One man's experience with a wooden pole. I "inherited" a number of Class 1 Western Red Cedar 65 ft poles from an obsolete government site. They were approximately 8 years old when I adopted them. Nin
But letting the tower leg condensation DRAIN is more important. And technically the tower should not be relied upon for structural reinforcing of the concrete. Nothing is more scary than to see towe

Sounds like three little 7/16" holes need to be drilled and then painted with Galvanize Spray paint -- spayed or applied with cotton swabs. Or if you really want to get serious than use a gas torch a
W0UN, with W0UA op, entered CQWW CW single-band 40M from COLORADO two years in a row in the late 1990s. Using two KLM 4L40s @ 80 and 160 ft, as well as an M-squared 4L40 @ 80 ft for mults, W0UN/W0UA
Unfortunately, the TH5 manual is not on the BAMA site. What other sites are there that might have the manual? W0UN _______________________________________________ ___________________________________
Gee, I knew about the Hy-Gain manuals on the Hy-Gain site. And BTW there are Alpha amp manuals on both the BAMA site (legacy) and the Alpha site (more current products). But what I was wondering was
I did a lot of climbing alone over the years. Only way to solve that problem was a divorce and find a new wife who was more supportive of my hobby! ;-) Although I always free-climbed in the past I ha
For the past 30 years or so, whenever I heard about a tower accident, I tried to find out as many details as possible in order to be better educated and to possibly avoid making the same mistakes. An

Don't waste your time with the above page. It was last changed over 10 years ago and is completely out of date and most of the links are broken. Dr. Christy is director of the Earth System Science Ce
Derek-- Poly, as in polypropylene rope, available everywhere, suffers severe UV degradation in a very short time period. I REALLY don't like polypropylene! Don't waste your money. Nylon is VERY stret
