Command History
Usage Guidelines If you perform a loopback of the RF module while the transverter is attached to an antenna, some
transmit power is radiated. Therefore, it is extremely important that you set the transmit frequency to
your assigned and licensed band frequency. If the transverter is not attached to an antenna, attach an RF
termination device to the duplexer port.
Examples The following example shows how to initiate a local RF loopback on the main antenna with the lower
half of the subchannel:
Router(config-if)# loopback local rf main 2
