Howdy, TowerTalkians -

    I recently posted a problem I was having with a T2X install which was too 
big for the HG-55 tower it had come out of and I couldn't see any way why it 
had worked for the previous 5 years with an apparently fatal problem.     When 
originally installed (I didn't do it), they ran into the same problem. Their 
solution was to capture the mast with the Yaesu thrust bearing and allowing 
enough room to install the rotator on the mast so that it was in a position to 
avoid the contact with the diagonal braces. THEN they brought up the non-welded 
rotor plate and attached it to the rotator so the plate is floating and not 
taking any vertical weight. All it's doing is keeping the rotator in place and 
counter-acting the rotational torque and the entire apparatus is held up by the 
TB.      Well, it worked but what a PITA because you're working in 3 dimensions 
and only have 2 hands.  Usually the last thing I do for an install is align the 
antenna. There wasn't the chance to do that as everything was floating and we 
had to do the best we could and then calibrate the actual heading with the 
adjustable meter excursion on the control box. WHEW - I was glad to get this 
taken care of.      The job could have been made easier if they'd have used 
some sort of quick disconnect for the cables as this was something else that 
complicated the job since they had used the original terminal strips AND barely 
left enough slack to secure the control cable. Nothing was easy on this job.    
  One of my criticisms is that most installs are done with little regard to 
possible (probable?) repairs in the future. The repairs can be easy or 
difficult depending on how much thought goes into the job. The same can be said 
for various tower appurtenances such as weather station devices and lighting. 
They just make things more difficult. I'm just saying - hi.     So it wasn't a 
poltergeist after all. Yes, a little disappointing but all's well that ends 
well!  Cheers & climb safe,Steve    K7LXCTOWER TECH
