[TowerTalk] Attaching to the side of a crank-up

[Mickey Baker]

I'm DEFINITELY going with a set of KF7P's curved standoffs. I think that's
my best protection against feed line entanglement, given the characteristics
of winds here.

There are lots of great ideas here, but pictures are great!

If there's not already a place to do this (with ads from the sponsors of
this list, hopefully!) I'd be happy to collect photos on this topic and put
them on one of my photo accounts for reference.

As some of you know, I'm in the mid-phase of a tower project - permit in
hand, base poured and getting the tower ready to stand up - and this list is
an INCREDIBLE resource.
