My LM-470 (70ft.) motorized crank-up TriEx tower has been in service for
about 5 years. It's the nicest tower and the best tower investment I've
made. When I called Karl earlier this winter to get his input on proper
maintenance for that tower, Karl provided lots of help. We recently
moved the tower to a new QTH. My XYL and I set it in place, attached it
to the new base, attached the 7 element beam, and cranked the tower into
position. A really smooth installation, again. I'm not fond of
climbing and, after two back surgeries, climbing hurts my back. Plus,
I freeze up at heights. The crank up feature really looks better and
better as I get older. I highly recommend Tashjian (TriEx) towers.
That's my $.02 worth!
