I have an old Tri-Ex tower (W-51) that was put up in August 1984 and on
which I have changed the cables only once - a month ago! It survived about
half a dozen storms of 80 mph peak winds, and the cable never failed. It had
a 10 foot galvanized mast and a KLM KT 34-XA on it until last August. It now
carries a 20 foot chromoloy mast and stacked Force 12 antennas. I replaced
the original cables with new 3/16 , 7x19 cables and plan to replace them
more frequently with the greater load the tower now carries. In the past I
left it at full height unless there was a storm forecast or strong winds
that were evident. Now, I keep it up when I know I'll be using the station
frequently, but retract it when it will be unused for long periods.
