Note: The OEM is free to choose another vendor’s antenna of like type and equal or lesser gain as an
antenna appearing in the table and still maintain compliance. Reference FCC Part 15.204(c)(4) for
further information on this topic.
To reduce potential radio interference to other users, the antenna type and gain should be chosen so
that the equivalent isotropic radiated power (EIRP) is not more than that permitted for successful
communication.
