[BC] Air-Dielectric Sections

[Rob Atkinson]

okay cool--glad it worked, since the only other idea i had was to blow a 
million BBs down the conduit ahead of the feed, using high pressure air, and 
hope the feed could roll on them.
someone should make little ball bearing rings, strap around the feed, one 
every 5 or 10 feet...just roll the heliax through the condit.  this assumes 
the inner surface of the conduit is smooth at the joints.  this is the kind 
of thing you'd think Andrew would come up with for long runs.

We pulled a 7/8" and two 1/2" plus a 12-2WG Romex and 4 Cat-5's thru about
230 feet of 4" last summer

used a quart of Ideal Wire Pulling Lube, dumped about half down into the
first 90-degree sweep, then at about 120 of cable pulled dumped the rest in

we had two guys on the pull rope, I was feeding the cable up over my
shoulder and down into the vertical pipe in the floor of the building, and
had two guys dragging/feeding the cables to me

We had 90-degree 'long sweeps' at both ends, it wasn't too bad

The biggest problem I see with trying to pull 4" is that it's so damned
'unhandy' to work with (and heavy!)
