a pipe sheave, or tie rope around pole 6' above end of pipe and throw a pulley on rope
That's one way we do it, a choker around the pole with a sheave, or we feed into the top of the riser on the pole and pull out on the other end. Depends on a few variables.
Regarding the variables mentioned, if you need to pull the conductors/cables around the sheave, you may want to use a larger one than pictured to keep the bend radius larger than the manufacturer's minimum radius spec.
