That same guide is offered at the Woodworkers site, but DX Engineering has them beat pricewise, not counting shipping. Not having used either one, I might lean towards the all steel guy as I would pr
From all that I've read, the most effective way to lightning protect equipment is to make sure that no strike current flows through it. That can be approached by tying all the grounds together at one
I have to chime in too. This idea of only connecting the antenna & control cables when you're going to operate and not relying on a properly designed and implemented protection system begs hurt. Ther
Hmmm... took out normally rugged appliances. "Cook stove, dryer, etc." These have, or should have, only one path to ground, back through the power cabling. Sounds like the strike came in on the L1 an
re: ## 1 - Actually, Jim, this brings up a question germane to my 100 A panel ca. the 60's. The surge shunts, the fused MOVs, connect to the line side of the main disconnect breakers, correct? If so,
Gentlemen, ladies, I'm in the process of repairing my standalone garage (replacing some of the Dutch Lap siding and of course, painting) to use as the upper support (by wall bracketing) for about 40
IIRC you tie the coax shield to the tower at its base for two reasons, with a kinda common thread. 1) To eliminate any possible side flashes through the coax's outer insulation, thereby saving the ca
On another tack, from what I've read, not having the rebar interconnected, that is, welded to itself and to the tower bolts is a recipe for concrete block destruction from steam bursts during a light
To all; An aluminum grounding plate is not such a bad idea, provided that you deal with it properly. First, the simplest is the use of an Internal Tooth Star Washer between the lug and the strip. No,
To all; A long, long time ago, I sat through a "grounding and shielding" course provided by my employer by a company involved in making sure that the guy in the black van in the parking lot couldn't
Hello all; A few days ago, I received my monthly issue of Utility Products magazine. "http://www.utilityproducts.com/articles/print/volume-18/issue-4/product-focus/transmission-distribution/managing-
Hi all, I need to get a rough estimate of what it would cost to install a ground mounted, self supporting 55 to 60 foot tower, supporting a 6 meter ground plane. Cost would include... say a run of LM
Well, it looks like I need to be a bit more specific. But, so far I've received some education... no 25, or 45 "G" as it will not be safe at the heights I mentioned. So, an actual free standing tower
Now if you want to talk butane soldering irons, let's take a look at those from Master Appliance. I have a Solder Pro 120, have used it for years. Used it to solder 58U cable to 3/4" Motorola (NMO) m
And I have a pet peeve with all of this. I remember the furor raised over the motorcycle helmet laws. They may be the right... the smart, thing, but why should I be forced to do "the right thing"...
OK, it just crossed my mind... happens once in a while. If you're feeding the Windom with co-ax and you expect the shield to radiate, which of the legs is the shield tied to? The long one or the shor
I can offer you a quick and dirty which we use at field day on hanging cables, just "whip it". Google "whipping rope" and you'll see a simple technique of wrapping light cord around twisted rope to k
Not "may", but WILL. I've pulled out fender mounted mobile antennas using the standard 3/4" mount and angle bracket. The volunteer fire guy specials. The unsealed cable shield acts like a soda straw.
Check out this link. Has a good bit of the book in bits and pieces. "http://www.smithspower.com/brands/polyphaser/services/media-library/white-papers" Stan You need "good grounding" for the arrestors
When the potable water safety solder came out, I read up on it and saw that it claimed about three times the strength of 50-50 lead-tin solder. Anecdotal evidence on< Put up a two element co-linear,
