Ray,
Thanks very much. I guess that rotor cable would be too lightweight?
I know that this tower design has been around a
long time - I didn't realize 40 years. The winds
are mostly gentle in my area of S. California so
I'm hoping for 65 feet extension without too much
sway. I'm putting a Steppir DB18 (96 pounds) on
it. I will be able to supervise my tower
traveling up and down outside my shack
window. The shack is just 20 feet from the base. 73, Howard W6HDG

Howard,
The cable should be 8 conductors, and depending
on cable run, 14ga or 16ga. There is no large
current traveling in the conductors, mainly control signals.
I have a 40 year old MA770 in the air, but would
think the mounting of the limit switches and
type are different. I took off the limit
switches on mine, and because of winds, only raise the tower about 2/3 height.
I do have photos of the originally mounted limit
switches but may take me awhile to find them.Â
Send me a personal email and I can send you some photos when I find them.

PS, there was another ham on this reflector who
was selling his MA770 about 2 - 3 months ago.
You may want to search the archives for him. His call may be N2JFS???

I've got a US Tower MA-770MDP on order with the
RMC-1000 remote. I want to prewire my shack
before the tower arrives. Does anyone know the
specifics of the required cable - how many
conductors and sizes? I don't imagine that US
Tower will be providing this cable, will it? Tnx Howard W6HDG
