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?

When you say renewing the lease, do you mean that the tower and lease already exists and that it has expired?  If that is truly the case then you are in a unique situation and you need to very carefully consider your options.  

Who owns the tower and who are the tenants on the tower?
