[Moon-net] Building a non metallic Mast

[John Maetta]

Wilt,

I used two 4.5' sections of 2.5" PVC pipe and inserted a wooden closet pole 
(dowel) inside them.  The dowel fit almost snug.  Then I alternated srcews 
long their length to further strengthen them against warping.  These two 
sections are inserted 1'  into each end of a 7' section of aluminum stock to 
give me the required 14' horiz. stacking distance.

You can view this setup at www.n6vmo.com.  Look in the N6VMO Stacked EME 
Array folder.
