40 meter groundplane questions

Update.... *After careful consideration of all the points raised here and also a lot of thought on the mechanical and structural aspects of things, I have decided to just go with ground mount setup with radials. I had thought of building some type of lightweight vertical radiator and mounting it atop the mast but I am trying to work with stuff I have on hand. I can't afford to invest any money into buying any sort of aluminum or other material to make such a radiator. As it is I will be stripping insulation off of wire to make ground radials as I have no bare copper. I once read somewhere not to use insulated wire for ground radials if you wanted them to be part of you lightning ground as well. *One problem I'm going to have though is with the mast being mounted against the house. This is a manufactiured home and I have a crawl space under the house. In order to try and get the best results I was thinking of actually running some of the radials underneath the house in the crawl space. I f I don't do this I will have radials running out in three directions and will have a whole area of the ground covered up by the footprint of the house that has no radials. Hope that makes sense. *Anyone see any problem with running radials on top of the ground under the house in the crawl space area? Other than having to watch out for them when I go under there of course. |
