I mean 46 feet. The cable in question is the brake status cable that
reports when the brake is on.

You need to swing a dish that fast when you are tracking a satellite or
space shuttle going very close to overhead at a relatively low altitude
(100-300 Nautical Miles). Our old antennas have to swing 15 degrees per
second in azimuth to keep up. What is truely impressive is to watch one of
our 60 foot antennas (220,000 bearing weight) move at those speeds. We are
currentily intalling smaller 13 Meter dishes that will not have to move so
fast in azimuth due to a 15 degree bend in the antenna riser that moves so
you can avoid the "Keyhole" (when a satellite comes overhead) tracking
problems.

Off topic but part of the discussion on wires,

Replying to the vibration part of the earlier discussion, we have a 46'
parabolic dish that moves at 15 degrees per second and we continiously
have
the crimp connector fail on a bi-yearly basis. We have done engineering
studies with solid wire, braided wire, soldered connectors and crimped
connectors but they all failed. The solid conductor seemed to fail
earlier.
We think it is weird and have replaced the entire cable harness twice
(cost
was in the hundred of thousands) but the problem continues. Our other
46'
antennas do not have this problem.

Why in the world would one need to swing a " 46' " parabolic dish
15degrees/sec????

Do you actually mean 46" as in Inches or do you really mean 46' as in
feet?

there seems to be some ambiguity in your post. Inquiring minds would
certainly like to know.....
