United States FCC - Continued
To reduce potential radio interference to other users, the antenna type and its gain should be so chosen
that the equivalent isotropically radiated power (EIRP) is not more than that required for successful com-
munication (listed below).
The system antenna(s) used for the following transmitters must be installed to provide a separation
distance of at least 20 cm from all the persons and must not be co-located or operating in conjunction
with any other antenna or transmitter.
