The RF jumpers transmit radio frequency signals. One end of the RF jumpers is the SMA 
straight male connector, and the other end is the type N connector. 

 

If the RF jumper is provided by the customer, the jumper must not be lower than the 
RG316 specifications. In addition, the jumpers can be used after they are checked by 
Huawei engineers. 

 

pRRU3901s can be connected to external whip antennas or external remote antennas 
(through pRRU3901 RF jumpers). Whip antennas are delivered optionally. RF jumpers 
are not delivered. 

 

For details about the cable connections in the different scenarios, see 7.5.3 Cable 
Connections (Indoor)and 7.5.4 Cable Connections (Outdoor). The installation of RF 
jumper cables are the same. The following section describes the connections between 
antenna and pRRU3901 in the indoor scenario as an example. 

 

In the outdoor scenario, RF surge protector is needed to provide surge protection for the 
RF ports. For details about the installation of RF surge protector, see 13 (Optional) 
Installing the RF Surge Protector and Cables. 

Step 1  Expose the SMA female connector by removing the pRRU3901 antenna housing, as shown in
