Re: [Repeater-Builder] Repeater Grounding
Dear Glenn, I would very much like to get a copy on CD. Only wonder how I could reimburse the expense of sending it to me. I sent you a message direct to your address but did not receive a reply. Hence this message. 73, George, VU2GT. - Original Message - From: Glenn Little WB4UIV [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Saturday, August 06, 2005 6:42 PM Subject: Re: [Repeater-Builder] Repeater Grounding I can send you a copy on CD if you want. 73 Glenn At 02:20 AM 08/06/05, you wrote: Hi chaps!

Glenn, I went to the below mentioned link and it comes back with page not found. If I delete the last part referring to the file name, I get into tscm.com but there is no reference to the grounding article. Is there perhaps anything missing?

Hello to the list and here is my question. The repeater site I am working at has little dirt and lots of rock. I have to use a jackhammer for the fence post holes, I can't hardly wait - ha ha.

Re: [Repeater-Builder] Repeater Grounding
Rod, The electric utility industry is faced with the same problem when they install towers for transmission lines. The standard practice is to drill a hole into the rock, perhaps ten feet or so, and drop a 4/0 stranded copper wire down into it. The hole is then filled with a slurry made from sodium Bentonite clay. This clay is also called Montmorillonite. Its great virtue is that it expands in the hole, essentially making the 4/0 wire much larger in surface area and ensuring a low-resistance connection to Mother Earth. The enormous pressure developed as it expands causes the rock to fracture and make more pathways for current. This was exactly the way a good grounding system was created for a nearby (at Vandenberg AFB) rocket launch pad that was constructed in an area that is mostly granite rock a few feet below the surface. The Bentonite can be purchased in pellet form from any company that supplies the petroleum drilling industry. It's the stuff used to plug wells once they've been pumped dry. 73, Eric Lemmon WB6FLY [EMAIL PROTECTED] wrote: Hello to the list and here is my question.
