We have a triangular Antenna tower that is about 40 years old and stands about 30' high. I climbed 1/2 up to repair that security light that was mounted on it, but was Leary about climbing the entire height to work on the antenna.

Should I be concerned about climbing all the way to the antenna ? its not rusted out, but I am just concerned about how well its anchored in concrete.
I was not there when it was erected, so I don't know if they secured it w/cables while attaching the upper sections and antenna.

Are those antennas designed to hold the weight of a 200 lb person at the top ?

Thanks
