Every registered structure

Sorted tallest first. The registration number opens the FCC record, which shows the exact location and the owner's contact for the structure. A tower on your land that is not in this list is probably under 200 feet and away from airports, so it did not need registering — see why some towers aren't listed.

If you have a tower lease in Cook County

Find your structure above, open its FCC record and confirm the owner — that is the company your lease runs to today, even if a different carrier signed it originally. Before answering a buyout offer, put your current rent, escalator and remaining term into the calculator to see what the rent is worth and what return the offer assumes.
