4. Antenna type and connections
Stream1955 provides two antenna ports via microwave coaxial connectors.
Antennas with 50 Ohm characteristic impedance must be connected to each microwave coaxial
connector via a coaxial RF cable.
No external amplifier or tuning circuitry must be used.
Stream1955 was certified for FCC and IC compliance using following antennas only:
