[TowerTalk] HDX-589 rotor and coax arms and why I re-subscribed after many year hiatus

[n6sj at earthlink.net]

Mac-

I have a UST HDX589 with a SteppIR DB42 (240 lbs., 20 sq. feet wind load) on top turned by an M2 Orion 2800 rotor.  No problems in 5 years, with pretty good wind gusts here in the Santa Cruz Mountains.  Not sure how much larger an antenna than that you would be putting up there.  I did need to use Kurt K7NV's mast clamp to prevent slipping.

I use Chris KF7P's curved standoff at the top, to avoid a right angle bend in the cables, but they go through the factory supplied open loops the rest of the way down.  When I lower the tower, I arrange the cables into an 8-foot wide "figure 8 flake" laying across two lawn chairs.  No tangles, and very easy to raise the tower with no snags.

73,

My HDX-589 tower was built to accept the old Hy Gain HDR-300 series rotor scheme wherein the mast opening both in the top section and rotor shelf were offset from the more often used center-line.

I want and have made plans to use a SMALL old time Prop Pitch as the rotor of choice.

Does anyone have experience using the PP in this offset scheme. 
Presently I can't run the tower sections out to a point where I can check or install the PP, and even then I will want to drill out the rotor plate mounting hole pattern to accept the PP mounting pattern to keep the existing offset center alignment.

I feel reasonably restricted to the PP as my rotor of choice due to my antenna/s wind and weight loading.

In this same question I have discovered these new to me CURVED standoff arms offered by Chris KF7P, using these has a real appeal to me V. using old time LOOP arms where when lowered I have a heap of coax and control wiring mixed with Inverted V coax.

When raising the tower it's a pretty much PIA and nearly always requires
2 persons, myself and an understanding wife with a dog that regrets being in the middle of the wire heap.

What experiences can anyone share about using the curved arms and your satisfaction levels. From all that I can see Chris seems to have filled a real niche in our market needs and support.
