Well I like to use the gray electric conduit because the color helps it
withstand sunlight better than the plumbing pipe color. I used what is
called a two hole strap to go around the pipe at the flat part of the
gutter. I then used 4 or 5 inch galvanized or deck screws so the screw went
through the gutter into the board, fascia, that the gutter is attached to.
Depending on the amount of side pull anything more than 10 foot will flex.
My IF M antenna was just on top so the only pull is the wind load. Using it
on 160 the rope guys and the antenna wire itself should keep it upright.
For what it is worth I priced 10 ft. section of 1 and a half inch pvc
conduit two nights ago and it was $4.01 per stick. Plumbing was $4.51 per
section. Now some thinking conduit is made to bend with the proper heating
tools. "The plumbing pipe needs fitting to turn corners so. I'll still
take the sunlight resistant gray.
I faced a similar decision a few years ago when I needed tall posts for
chainlink posts. Electric conduit was cheaper but galvanized plumbing pipe
was chosen because it was not meant to be bent. Yes rigid galvanized
electric conduit can be bent.
