[Towertalk] RF transparent support poles

[Rob Atkinson, K5UJ]

Hi everyone:

I'm toying with the idea of experimenting with a 4 corner horizontal loop (a 
project after the next project). I'm on a city lot, 50' x 100' but I think I 
could get a 200 to 225 foot loop up at 20 to 30 feet (my lot is not level) 
maybe higher.  The feed will come down from the feed point along side my 
house with ladder line to my basement shack window which I'd replace with 
plexiglass.  I'll drill two holes in the center of the window & run the feed 
through to a balanced transmatch which will sit right there at the window.  
Only one problem so far:  I need 30' high rigid non-metalic supports, 
preferably unobtrusive looking.  I was at home depot a few days ago and they 
had these 4" diamater pvc sewer pipe sections but I figure I'd land on the 
city eyesore list if I put up four 30 foot high white columns of plastic all 
around my house.  There are a lot of people around here who are uptight 
about this kind of thing.  I am interested in avoiding metal because I don't 
want to detune or distort the patterns of my verticals.  Also, to get the 
longest wire possible I'd like to put the poles close to my property lines 
and that means they would have to be unguyed since any guy anchors would 
have to be outside my property.  Ideally something black or green that I 
could stick in the ground several feet to which I could attach an insulator 
or pulley at the top and hold up thin stranded cu wire (but heavy enough for 
1.5 kw--I don't believe in antennas with the word junior in their names) and 
a little bending at the top.  Willing to paint.  Fiberglass?  Any 
suggestions? Tnx & 73,
