We will contact the owner of the cell antenna and ask a third party to take measurements. We will review the report and share it with you. If the radio frequencies are over the safe level, the owner needs to fix it.

The Federal Communications Commission has standards for safe exposure to radio frequency. Learn more about radio frequency safety.
