Hi Doug,
Two inch irrigation tubing fits perfectly into 2" PVC electrical
conduit (which makes a perfect insulator) which fits nicely into DX
engineering 2" U clamps. I use it for insulating the driven element of
my homebrew 40m beam which is also constructed from 2" irrigation
tubing. Works good and last a long time. I've used bare wood also and
haven't noticed any negatives from using the pressure treated wood.
Have Fun,
dave
