We had to find a safe solution for climbing steeps roofs to install
WISP antennas. For several months I could not figure out how in the
world the other guys were getting up on 45 degree 35 foot tall center
I found some J-Hooks to attach to a 42' aluminum extension ladder. The
link is: http://www.slateroofcentral.com/store_lad_hook.html
They have one with and without rollers, company told me both meet
applicable OSHA requirements. We place a 22 ft fiberglass ladder with
standoffs against the outside wall and two guys can get the longer
ladder on the roof.
Don't get me started on how the other guys ground, err...don't ground
their outside roof mounted antennas.
