Which is better and why?M2 2800 or whatever they call it now,Prosisteil
PST-61 or Hy-Gain HDR-300.Looking for a stout rotor to turn some big stacks
of uhf beams in a high wind area.I have a PST-51 up there now but I keep
shearing off the "pin" bolt and I don't want to put a bigger one in and then
break the rotor.Plus I think the bolts that hold the rotor plate to the
rotor are getting stretched which means it can turn 20 dergrees or so back
and forth and then that puts a lot of torque on the "pin" bolt and then ping
it breaks.The "pin" bolt is grade 5 3/8*4 with a grade 5 cap screw.It does
indeed break as to just getting lose and then fall off.  Gregg  K9KL
