There are two antenna-mounting configurations available for the ASR 901S Series Aggregation Services
Router:
Direct Chassis-Mount AntennasInstall the chassis-mounted antenna directly to the antenna port.
For instructions on installing the antenna on the router, see
Installing the Chassis-Mount Antenna on
the Router, on page 59.
External-Mount AntennasConnect the supported Cisco lightening arrestor to the N-connector, and
then use the antenna feeder cable to connect the antenna (female N-connector) and lightning arrestor.
Installing the Chassis-Mount Antenna on the Router
The antenna is vertically polarized. Because the antenna has vertical gain, it is very important to mount the
antenna in a vertical (not leaning) position for optimal performance.
