Would you care to define "ground loops between pieces of equipment"? Here are my thoughts: An equipment ground loop is a condition where potential (voltage) can be measured between the chassis of two
of any utility above 2 MHz. OK. So where is the proof? I am thinking any writing you can find is based on the use of braid that of poor manufacture or has corroded, or both. Poor or corroded braid c
Frank, I understand your beliefs, and your explanation sounds reasonable, other than the pressure of the jacket on braid part. The pressure would only be needed if the braid were loosely formed aroun
Now this is the most plausible explanation seen so far. Basically it seems that there is no valid reason to have measured evidence if one follows sound engineering practice. Makes perfect sense to me
It certainly speaks a lot of Tom's consistency. <grin> Keith --Original Message-- From: towertalk-bounces@contesting.com [mailto:towertalk-bounces@contesting.com] On Behalf Of Jim Lux Sent: Sunday, J
Oh noooooooooooooooooooooo. Here we go again. I'm going to bed. 8^) Keith NM5G Why do I get this message every time I send a post to Tower Talk??? Any ideas? Is this guy a subscriber with a broken em
No offense Jim. Please do not unsub. You had to be here to understand it was a joke. Keith NM5G That's fine smart guy.....Laugh all you want. I just subscribed to this list about 5 days ago.... To ma
AES is the vendor for my Harger bar. The bar was shipped with a few short braids and stainless hardware for mounting. I almost included that roll of 3 inch copper in the order but figured the 1.5 inc
There are already two 8 foot rods just outside the window. Why would I need more? And if the argument is for better grounding, please indicate your thoughts of the percentage of reduction in impedanc
Same here Bud. My guess is most hams have been frustrated by this task. Here is how I solved the problem once and for all: 1. Obtain a professional temperature controlled soldering iron with moderate
Thanks David. Here is a photo showing placement of the rods. They are about 1 foot away from the slab. http://www.dutson.net/Ham/P6060006.jpg Keith NM5G Depending on the spacing of the 2 existing rod
I read Polyphaser's technical note before installing my system. There is a lot of discussion about soil conductivity and how adding more rods will improve conductivity. Do you have an idea of HOW MUC
It cannot be seen from the photo, but these rods are connected together underground and the same buss that connects them also runs to the tower ground rod system, the power mains ground rod and the t
Well, different strokes for different folks. I have not had one single failure in about 200 PL259 applications. That's 100 percent success. Good enough for me. BTW, this procedure is for the full siz
I think the key to vertical installation is the local water table. If I dig down 8 feet I always hit water. In rainy months the water is found a foot down while in a dry period it is about 6 feet. In
I have 1.5 and 3 inch strap on order to replace all braids in the shack. What is the best way to terminate the ends? Thanks in advance. Keith NM5G _______________________________________________ See:

I would definitely contact US Towers on this. You are risking a lot. That is a monster tower that deserves your full attention to detail. Keith NM5G I have a UST HDX5106 tower with TRX 100HD raising
I would purchase new Rohn bolts. Texas Towers may have them in stock. Keith NM5G I took down my tower a few years back and discarded the old, rusted bolts. I cannot find a listing of the sizes for th
There is no stamp on them that I have seen. However the ones from Texas Towers are hot dip galvanized and fit the holes perfectly. And they do not rust. Keith NM5G Does ROHN use special "ROHN bolts"
