[quote:9290068d15]Must ground radials be placed symmetrically? I seem to recall reading something about that. I’d probably be able to get them 120-150 degrees around my antenna, out into the yard running away from the house.[/quote:9290068d15]
Yes Scott, they have to be symetrical to obtain the optimal, desired propagation characteristics. Even on commerical phased arrays that have multiple antennas, the radials are symetrical around each antenna within the array.
[quote:9290068d15]I feel i tmay be easier to lay out a ton of radials then have a few dumptrucks of dirt to spread over it all… Thoughts?[/quote:9290068d15]
Jason, many years ago I heard about a fellow who was putting up a new AM commercial station. He and an employee hand laid all 360 buried copper radials with a type of hand trenching tool. I am not “handy” enough at outdoor tools to know what it was. I also have no idea how long it took.
I believe that “Invisible Fence” (TM), which is a buried copper wire system for activating dog training collars is hand laid with a special type of trenching tool that basically pushes the wire a few inches under the top of the topsoil. While I have never seen the actual tools they use, the lawns look pretty good shortly after installation, so it probably isn’t too “invasive.”
