The following figure shows a typical method for connecting an antenna cable.
RF antenna connections
The RRH accepts two RF antenna cables on top of the unit.
The connectors are 7/16 DIN. One 7/16 DIN connector is for Tx/Rx, the other is Rx-only.
An external RF surge protector is not required.
RF antenna cable requirements
The RRH can support up to two RF antennas per one-sector configuration with
transmit/receive diversity. The RF antenna cable must satisfy the following requirements:
•
Impedance: 50 ohms
•
Attenuation: < 3 dB
•
Antenna jumper cable at the baseband cabinet end must be equipped with a 7-16 DIN
center pin straight male connector.
•
Surge protection (not required for outdoor)
•
