What are good practices when renewing a Cell Phone Tower Lease?

[Jennifer Hamilton]

I am renewing our cell phone tower lease and was wondering what the going rates are all over the country or in South Texas? Is there a signing bonus? If yes How much? How is the insurance handled? How can you attract new companies to lease off our tower? If leased & the current provider sub leases to other cell phone providers what is the shared percentage? And who is a good Cell Tower Attorney to help negotiate the lease?
