[TowerTalk] COAX on CRANKUP-how to hang

[Grant Saviers]

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.
