Jon,

     Really appreciate your comments on TT about the RR55.  I have a 
question about the capability of the RR55.  On the ProSistel page it 
lists the max weight at 45 kg and max wind area at 1.5 m2.  I have a 
C31XR JK version antenna on a Rohn 55G at 50'.  It's rated at  110# / 50 
kg and 18.6 f2 / 1.73 m2.  These numbers are just a bit outside of their 
ratings.  In your opinion, do you think their ratings might be a bit 
conservative and I would be OK with this combination?

     The reason I'm asking is that I have been dealing with a TIC ring 
that can't seem to handle this antenna in the wind.  I have been in 
contact with Carl at TIC for nearly a year now asking for a solution.  
The motor he uses is too wimpy and the motor and direction indicator 
gears keep losing contact with the ring making it go out of calibration 
or give a "no motion" indication on the controller.  He says he has a 
solution for both issues but nothing has been sent my way.  It's always 
excuses that he needs a bit more time.  The RR55 looks like a good 
option.  How responsive is ProSistel to issues and delivery?

     TNX es 73,
