Topband: Looking for ideas for ground mounted vertical mounitng scheme (base insulator especially)

[Mike & Coreen Smith]

Hi All,

As I was mowing today I wondered when I would ever get around to installing 
my 160m vertical I had planned to do a year ago.
What I have in the ground is an old chunk of concrete aprox the size of 
large pumpkin.  This has a 1½" (aprox) pipe embedded in it aprox 2' long in 
total. Goes all the way through, so it's touching earth.   I actually found 
this down in the woods when I bought the property.  MOstly likely the 
remnants of an old fencepost, or tetherball pole.  Anyways, I dug a hole and 
got most of it in the hole. I estimate it weighs 200lbs?

I have various pipes here and could probably build something 50'-60' tall 
and attach a 3-wire wire tophat to it, but I am wondering mostly about 
attaching the vertical to the pipe in the concrete.  I would presume I would 
want to isolate the pipe, yet physically attach it to the vertical section. 
Surely some folks have done it.  What do you use?  Painted wood?  Some kind 
of PVC method?  Are there fiberglas items that would do the job?  I'd like 
the base to be as strong as possible to use less guy ropes.   Anyone had any 
luck with really big fishing line? (to minimize visual ugliness?)

Anyways, looking for ideas. I've stared at this for a year, sticking up out 
of my lawn, so time to do something with it, hi !

Thanks,
