Hi: I tried to put a page in above ,But for some reason it did not work so i asked Mram what could be the issue.
It does talked about sea water, And how it does increase am tx range.
If you look on my blog i do beleive i have ground section and what you can use. like cat litter( I was told from a company who installs part 15 am tx units as a business is what they do ) for example do to it holds moisture & drain field from septic systems, or a drip system on your grouns system.Just a few example.
station 8
If you like to have a lawn LOL! 🙂
This ground layout looks better than a LOT of full-power AM's I've worked for over the years!!:)
A former "Mom and Pop" station in the Lakes Region of NH laid their original ground system in the WINTER!! The wife climbed the tower and directed the husband, who simply laid the copper radials on top of the snow....and let them "settle" as the snow melted!!
2 guys laid the radials (120 in all -- 60 x 50', 60 x 150')....4" copper strap was used for tower/transmitter bonding......
This was when the station first began operation @ 1kw....they later went to 2.5kw and 5kw, and "beefed up" the ground system with each power change......By the time the Harris MW-5A was installed (1981) there were , IIRC, 240 radials in the ground.....
Need I say it....a SUPER job, wdcx!!:)
Nice job! That is the way to go with Part 15. And Jeff (Station 8) is spot on about 8th Wavelength radials. I'll tell ya, Jeff is the authority on Part 15 AM Antennas! After doing a small bit of research, I find great value in his testing and results!
I would say, WDCX, you have the TEXTBOOK radial setup!

That is nice. You ought to assemble and sell them!
This is exactly the approach that I was planning. I've got plenty laying around the property and planned on buying the rest at Lowes.
corrosion is an issue.
I fabricate with stainless steel for a living and it's about the only thing that won't corrode much. It has to be "300" series SS or better, not cheap stuff that sinks are made out of.
Insulated copper is best if you are concern is about corrosion. The resistivity of stainless at RF does not lend itself well for ground radials.
SS is a crummy, I would think, is lousy for anything radio frequency.
Use landscape staples.
This is what I referred to as landscape staples.
I like to have a lush green lawn, i just hate mowing it lol
