Rick I have the 89' heavy duty UST (3000 + LBS) that over the years I have
had both heavy and light antenna loads installed on it. I can tell you that
if the 106' model is balanced as well as the 89' model, and I have no doubt
it is, you will have no problems when the tower reaches the vertical
position. There is really nothing to do but just keep your fingers and toes
out of the way. It will just rock back into position with little or no
I think one of the reasons this happens this way is there is a little
friction caused by the back leg mounting plate against the rear tower
mounting flange. This friction probably causes the tower to rock back in a
more controlled manner.
The tower is so easy to use that many times I have cranked the tower down,
laid it over then either replaced or serviced antennas, then stood it up and
cranked it up in much less than a days time. All of this with no help.
If you have any further questions I'd be glad to talk with you either on the
phone or via e-mail.
