I started with the KF7P arch standoff setups on two HDX589s. These are
the version that hold the coax off the ground. One worked perfectly and
the other I couldn't make work as the wire bundle insisted on catching
on the arch on the way up. So, I worked with Chris for the proper
spacing and offset design for 589 dimensions for oversize wire loop
guides and he swapped them for the arch versions gratis. . Both towers
have 3 x 9913F7 or Buryflex, 1x rotator cables (Yaesu/Orion), 1x RG6 and
1x 6x18 control cables.
I have never been of the school of remote remote raising/lowering. It
only takes one snag to create a really big problem, so I always observe
and need to be present anyway to figure 8 flake the cable bundle as it
comes down. My cables were installed with no twist and I want them to
stay that way.

Anyone out there using the KF7P standoffs or similar and have had
snagging problems while raising and lowering your tower with or
without observation while the tower was in motion? If so, what seemed
to be the problem? Was it wind induced or otherwise?
I think there are folks out there who routinely raise and lower their
towers remotely without observation and experience no problems. It
would be great to know how they do it. One of my to be installed
towers will be 300 ft or so and not always fun.

KF7P makes very nice stand-offs and not too pricey -- especially
compared to the price of the tower, coax, control cables, etc..
www.kf7p.com. I have no pecuniary interest. Just a happy customer.

Stand-offs are a high prices accessory...great profit margin! Like
you have had crank-ups for decades. Never had an issue with rotor
cables or coax... Subjective opinion of one....YMMV.

I have owned crank-up towers for close to 40 years...in multiple

In all cases, I just let the coax and rotor cable "hang down" right
along side of the tower.
I never used standoffs or coax arms. Not sure why they are necessary.
Nothing ever got tangled or "hung up" in the tower. I think that
would be really difficult to do.
I mean, why would coax (eg, RG8 type) want to or be able to "decide"
to bend and enter into
the tower lattice? It is already handing from the very top to the
very bottom. For me, it would
take an extraordinary act of nature to "convince" the coax to defy
gravity, bend into a small
loop, and "enter" the tower lattice.
