OK, bought a bat house to attract bats to my property. Bat enthusiast websites recommend mounting it 15 to 20' up on a pole. I would mount it on a tree but have none that would allow it to get the morning sun they recommend. I went to Lowes and saw 10' sections of electrical conduit were +$30 apiece. Holy cow. I would need 2 sections but am not paying that much to do this experiment. I tried 1" thinwall (EMT) conduit but it had too much flex to mount the bat house at the end of 2 pieces. I need something more rigid like regular conduit maybe 1 1/2". I thought maybe a couple 10' 2x4's joined together - that might work and be affordable. Any ideas of other ways (cheaper) to create a 20' pole?
