tower structural analysis

Post by grich » Thu Jul 05, 2018 10:54 am

Looking for recommendations on a firm that can do a structural analysis on a 117m tower needing a translator antenna mounted. I can't find any specific documentation on the tower, and it's had some ham and two-way antennas added to it over the years.

I do believe the folks at Electronics Research in Indiana can help you out. Also most top notch tower companies will have degreed/licensed structural engineers on staff and can provide that service---usually at a pretty high cost.

You can be pretty sure it won't meet current EIA spec. Be prepared to pay upwards of $1500 to be told that, and another $2000-$4000 to be told that it needs $10,000 worth of reinforcement.

Yep. It's been around awhile. I think it's a Utility tower from what little I've found. I do know who worked up the application for the FM at this site...

Fossil, you should know better than that - Mark's answers to many questions here show that he's an old fart like you and me. :-)

Not having a normal uncomplicated life is a major reason why I never married. Having a cell phone (or in days of yore, a pager) go off a 3 AM is apparently a romantic no-no.

I've been fortunate to have found a tolerant spouse who has put up with the BS of broadcasting, and me, for 37 years.

She's also helpful. In a past life, she helped with audio proofs. When this particular site built a new studio building two years ago, she helped build the wiring harnesses for the FM studio board...she's good with a DB pin crimper.

My wife Karen stuffed and soldered somewhere around 2500 tone detector PC boards; she's all in. :mrgreen:
