Topband: Hi-Z vertical elements

[W9UCW at aol.com]

Hi Gary,
 
I went the PVC route first for  my 4 element HI-Z. Same results as you but 
sooner. I ordered telescoping  aluminum tubing and solved everything. I used 
6 feet of 1 inch OD, 6 feet of  .875" OD, 6 feet of .75" OD & 3 feet of 
.625" OD for each vertical. The  pieces are overlapped 4 inches and one 
stainless steel sheet metal screw holds  each joint together. That makes a stiff 
vertical with low wind resistance &  no maintenance.
     
 
The bottom piece of 1"  OD fits nicely into 1" nominal PVC pipe which is 
then adapted up to  1.5" nominal PVC. That slips neatly into the 2" aluminum 
tubing that  serves as both the antenna mount and the ground rod required by 
Hi-Z. .  


The tubing is available from DXE  or Texas Towers among others. All four 
verticals cost me about  $100.
If anyone wants pictures, drop  me a line.
