Tom,
The Force 12 Sigma 5 would better survive mounted near ground level and not
up on a tower if you get any strong winds. It has only 50 feet of control
cable for its relays that must switch at the center feed point to select
matching coils for the various bands.
It is made of portable grade materials such as wing nuts to assembly the
sections, and lightweight thin elements of aluminum tubing.
I would not put it high up in open wind. It will work just about as well
six feet off the ground or less, down where the house and surrounding area
can shield it somewhat from destructive winds. As long as you have about 25
feet or more clear around it, it should do fine on the ground mount. We
used one such as this 2 weeks ago and worked lots of grey line DX Canada to
Venezuela from central Tx even with 20m in terrible propagation shape and
only 40 watts SSB.
73,
