It sounds like you have what we call an additional ground space clause. Rather than sharing in the revenue that a sublease tenant pays AT&T for the use of the tower, you have the ability to negotiate a separate (or additional) ground lease with the sublease tenant. For example, if Verizon contacts AT&T to add equipment to the tower, Verizon would also have to contact you to negotiate an additional ground space lease with you. In that case, you wouldn't receive anything from the rent that Verizon pays AT&T, but instead, Verizon would have to pay you directly for ground space for their ground equipment.
This is not the same as revenue share clauses. In a revenue share clause, you would receive a portion of the revenue that Verizon pays AT&T instead of being able to enter a separate ground lease with Verizon. We prefer a ground space lease over revenue sharing because our clients typically get more for leasing additional ground space than they do in terms of a revenue share. I think this is what you are referring to when you say "I'm trying to determine what other Grantors are receiving as a percentage of what the first Grantee (AT&T in my case) is paying monthly" however, that is a bit confusing because you wouldn't get a share of what AT&T is paying but what the 2nd carrier on the tower is paying under a revenue share agreement.
The value of an additional ground space lease is typical $400/mo or more. How much more is based upon how unique your site is and how difficult it would be for the second tenant to find another tower or build their own. When you are contacted by another carrier who needs to lease ground space from you in order to install equipment on AT&T's tower, please reach out to us and we can provide a quote for services to review how much you should charge.
