I just happen to be today building a simple 12 meter 1/4 wave vertical using this PVC I picked up at Lowes yesterday. I am using the pipe for a sleeve to insulate the bottom 18 inches of the Aluminum tubing of the vertical from its mounting pipe.
It says on the PVC pipe I purchased ......"Rigid Nonmetallic Conduit Aboveground and Underground Schedule 40"...... made by Cantex (http://www.cantexinc.com/ I am using a 1 inch diameter PVC with fairly thick walls. The antenna is fairly short and lightweight, being only 112 inches long, so it should hold up well. This is for my 12 meter beacon I will have on the air soon which will be next to my 10 meter beacon already going on 28.2185 MHz. Both antennas are on the top of my metal garage.

The reason I ask is I'm looking at encasing an antenna project for the sake of weatherproofing and PVC would fit the bill rather easily. 73, AJ, K6LOR On Mon, Aug 10, 2009 at 9:49 AM, AA8K73 GMail <aa8...@gmail.com> wrote: AJ, if you replace the steel mast with a fiberglass one, won't you still have the metallic feed line there?

I have quite a few surplus fiberglass poles left that would likely work, even for side mounting on 1/2 wave spacing from the tower... On that same note, does anyone have construction plans for a dipole array (not necessarily folded dipoles)? I remember seeing a set of plans somewhere quite a while ago - we're thinking of constructing one but encasing the dipoles in fiberglass or PVC to try to protect from the weather and debris at our site (top of a large farm field)... 73, AJ, K6LOR ---------------------------------------------------------------------------- Click Here View photos of singles in your area
