     Thanks guys for your input on the info about the DXE magnetic loop.  I guess I forgot to tell you it will be about 20 to 25 ft abv. gnd. just above my TV antenna I use for on the air TV.  This is the West end of the roof on my house.  I live in the dessert of Mesa, AZ so I also wondered about ground conductivity effect performance on the loop.  I'm sure I could just mount it low to the ground but this is really the best place for it, up in the air, out of the way. 
     Thanks Peter for informing me.  I've also did some research and got info on how to test the PVC's conductivity.  CPVC has content of metel particles in the elements for making it.  But regular sked. 40 PVC an no metel particles in it.  The proof is to take a sample of PVC and place it in microwave oven for 30 seconds with a bowel of water for the load.  If it's warm of hot, it has metel particles in it but if it's cool it has none.  And a very good insulator for supporting the loop to the top. 
      Once again thanks.  73  Ronny  KG7A. 

Ronny, not sure if it was already mentioned or not but be sure to paint the PVC in order to protect it from UV if it will be installed for a substantial amount of time. The portable magnetic loop antenna which my company sells is supplied with a knockdown mount which is made from 1/2" schedule 40 PVC pipe and it works well and is durable but not painted because the antenna is meant for temporary (not months nor years) outdoor and mostly indoor use.
