I may not be quite correct about the length of time but,
whatever it is, it ain't much. Because I'm using the Hy-Gain
HD300 rotator, the top section of the TX472 won't _QUITE_
crank all the way down.  IIRC, the tower is 28' tall when
nested.  The VERY heavy 15' L x 1/4" wall x 2" OD steel
mast protrudes out of the top of the tower approximately
11 feet, with my F-12 C-4XL just above the tower. I have
my Cushcraft AR10 adapted to fit the top of the mast,
adding another 16 feet.  Even with all that above the tower,
The Super Hawg doesn't flinch AT ALL. I necessarily need
to hang on, and make certain nothing is in the way because,
it's a monster!

 Bryan -
 
 That's fast! I have been trying to figure out how much
 hassle it would be to adapt the TRX80HD to the HyGain tower.
 If it's even possible.....
