Pieper had the same model lift and trailer there that you have pictures of at the site on 56th. They had two lines come down just like they do on the tower at 92nd now. Drove past the site on 92nd today with my girfriend in the truck and she could not figure out what i was so excited about. It may just be what they use when they do any work on towers but i thought i would bring it up. I did not take pictures since its a firehouse and i didn't want to go behind there without permission. The tower at 56th has 6 different types of cell antennas plus the array on top for the MPD and MFD communications. Before the work started there was i believe there was only 5. Not sure who is all on the tower but it would be nice to find out just out of curiosity.
