But if the lightning protectors are all tied into the same ground rod, isn't that the same as the SPG? Yes, but the box only shields the stuff inside the box. What about all of the coax that is run i
Not to disagree with Bill because he's been a BIG help to a lot of us here on this reflector (ME included) regarding station protection. BUT... I was confused about where to put my SPGP also ..My ori
I think I can summarize the concepts in this discussion as follows: 1) Ground everything at the towers 1 1/2) Have polyphaser protection at the towers 1 3/4) Coil excess coax in a circle, lying flat

What is being proposed is a common grounding point within the shack, which is a good idea. THIS IS SEPARATE from the single point common ground where everything comes into the house. If your shack is
OK, so how does one ground the phone lines and Cat 5 cables? Do you need to run them into special surge protection devices or are there grounding blocks available for these? 73, Jon NA9D -- Jon Ogden
Guy has it right. I couldn't have said it better. And my shack has all of what Guy says here. The SPG in the shack is a consolidation point (panel) for all of the equipment grounds in the shack and c
I guess the confusion comes from what is called the "Single Point Ground". In my mind when I started to research this stuff and to sort out all of the various opinions and implementations was to fund
Hello Jon, Uhm. Yes. There are surge suppressors both for Cat 5 (ethernet) and phone lines. You should seriously never plug in a computer to your phoneline without a phone line surge suppressor unles
Let's take this one item at a time: Phone lines (TELCO) come into the house from the outside (either above or below ground). Most, if not all, codes require TELCOs to provide lightning protection on
There's another series of Articles by Ron Block in QST in the June, July and August 2002 issues. When reading article's by Ron Block (or Polyphaser articles) the SPG refers to the single point as the
Part of the confusion here is that a made-to-order commercial radio room is usually going to be a single room inside a shelter, built on a concrete slab, and the problem is protecting everyone's stuf
No offense Bill BUT... Grounding does you NO good on a line that don't have any surge suppressor. If you go look you will find that the phonelines that comes to your house and a lot of others either

I don't have that luxury either...my shack is on one end of the house while the power and telco come in the other. Hence the perimeter ground to tie them together at the power/telco entrance. The tel

I did a little field research on the base/anchor grounding this AM while walking the Dog. Visited the WSB TV, channel 2 in Atlanta, tower base and two guy anchors. The guy anchors and base concrete a
Steel is a very poor electrical and thermal conductor, but there is enough of it in the legs of a 6' or more, faced tower to make any additional conductor un-necessary. These are "stock bridge dampe
Vibration dampers can be seen more commonly on high-voltage power lines. Mounted close to the tower ends of the power line conductors and/or on the overhead ground wires (which run from tower top to
