I had a DX Engineering radial plate on my P40A 160m vertical and had zero
corrosion. You could cut one in half to go around the tower.
Rolling up multiple attached wires would likely become a tangles mess.
You should be able to find suitable stainless steel angle at Mc-Master Carr,
drilling a Ø5/8 hole is easy. You could also drill multiple holes and bolt
the radials directly to the angle.

Jim,
Thanks for pointing me to that review. I looked at that picture. These
are 304 grade stainless. DX Engineering's plate is the same - 304 stainless
steel which is not the best for corrosion resistance. 316 would be much
better. Those in the review were installed on a table 100 feet from the
sea with the crappy sheet metal screws included that will definitely
corrode. Of course there is a huge difference between 75 or 100 feet and 5
miles from the salt water regarding corrosion.
My plan is to get all my radials attached and then perhaps spray the whole
thing with liquid electrical tape and deploy it when I am there for a few
months a year. Then I will roll the radials up and store it intact when I
am not there, relying on however many radials I have buried during the off
season.
In my application I want it around a tower which this will do and the DX
Engineering plate will not.
There are several sizes and the smallest one which would be good for a
vertical made from aluminum tubing would only cost $7.99 delivered. Can't
beat that deal.
What I need now is a stainless steel angle the right size and preferably
with a 5/8" hole to mount an SO-239 to the radial plate.
73...Stan
