First of all, and most important, a joyful holiday season and a prosperous New Year to all of you. Now down to microscopic issues that will probably have no bearing on World Peace... Let's be clear t

Guy, I am surprised at your findings. Is it your opinion that unstripped thhn is a no-go for in-ground radials as well? Would you please share "the method" Thanks, Matt W0MLD ________________________

You can deduce some of the secret stripping sauce from this old post of 0l' Guy from seven years back: http://lists.contesting.com/_topband/2010-09/msg00110.html Merry Christmas AG6CX Ed McCann Sausa
Guy, Please inform us of the details of the antenna and how the measurements were performed. A little google research provides a lot of data about PVC degradation, a exhaustive survey article at http

With all due respect to Guy and the other contributors to this thread, I am mystified by any deterioration in RF performance that can occur with antennas made from THHN house wire. Grant is quite cor

With such a high amount of copper theft some AM radio stations in Puerto Rico choose to replace their radial field with inexpensive buried barbed wire. They would plow it into the ground with a Ditch

Guy, that certainly makes sense since formation of HCl is known to occur, and it might indeed attack the copper's surface resulting in an increase in the resistance of the "skin." Frankly, I have to

On simple test for the performance of any radial, and I have used this method to detect broken buried copper at an AM station, is to run abut 20 watts into the antenna, then hold a good field strengt
I've just recently (re)subscribed to this list, so I don't have the whole thread, but this paper might be of interest: http://k6mhe.com/n7ws/Plating.pdf Wes N7WS On 12/27/2016 1:30 PM, jimlux wrote:
http://k6mhe.com/n7ws/Plating.pdf an excellent paper. I like the comments about how in a survey of 165 papers on electroplated copper that data on electrical resistivity are nearly non-existent. And
Stripping insulation from a 500 feet spool of #12 THHN from a big box store is easy-peasy. Once you've seen it done, you'll kick yourself in the butt for ever buying bare wire from the online stores
The big box price for THHN is also about 50% more than for Romex with three wires. Those three are fairly easily separated using a utility knife and some pulling. Guy's "method" has to be similar to
