They are constantly doing work on this tower I know its not the best photo but they just put these white panels on the tower I have checked and found that the tower is owned by STC Two LLC which is a subsidiary owner of sprint towers, my thing is, is that on the sprint website it's not marked for an LTE upgrade. I've seen lots of trucks with huge metal box like building things along with tons of people working in and out of there. I live in a small rural community in florida known as lithia, the sad thing is I'm just outside the 4g coverage of sprint. heres the link https://plus.google.com/u/0/113947387432572563827/posts
the site wouldn't allow me to post the photo.
