Dear Colleagues,

        I am at the point of installing antennas on the 23' mast on the top
of my US Tower HDX-572 (while it's on the ground).  I have the associated
UST tilt over attachment, which uses a Fulton K2550 Standard Work Winch, and
the cable shown for this winch is 5/16" dia, 7x19 Aircraft (8mm) cable.
When finished this tower will house 8 antennas on the mast, one being a
heavy TH-11DX HF beam.

        I'm concerned about the tension put on the winch cable upon raising
the system and would like to KNOW if I'm reaching dangerous cable tension
limits.  The maximum breaking strength of this size cable is shown as 9800
lbs (galvanized cable) on the CarlStahl website.

        What I would like to do is to obtain a device to measure the cable
tension.  I've been to the Dillon Website
( and found their
"Quick-Check Tension Meter."  

        I'm wondering if we have anyone who has used this unit and, if so,
I'd like to hear their opinion of it.  It's very expensive to purchase but
it's not much more than the HF beam and one more antenna.

        I've tried to locate someone who rents them but to no avail.  I may
consider purchasing one.  Any suggestions?
