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.
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.
