Antennas
The AXT630 and AXT631 are compatible with front-mounted antennas or with remote-mounted antennas.
When using the input band filtering function, select an antenna with bandwidth to cover the filter range.
Installing Front-mounted Antennas
Mounting the antennas on the front panel improves system performance by providing a clear signal path for the RF signal. Use the supplied bulkhead adapt-
er kit to install the antennas on the front panel.
1. Insert the bulkhead adapters on the supplied front-mounting cables through the holes in each bracket and secure them from the front using the supplied
hardware.
2. Connect the supplied antennas cables to the antenna input BNC connectors.
3. Install the antenna onto the bulkhead adapters.
Note: To minimize the possibility of signal dropout and optimize performance, point the antennas up and away from each other at 45° from vertical.
Installing Remote Antennas
Remote antennas offer greater flexibility for antenna placements and can improve performance by providing a less obstructed transmission path and extend-
ing range. Consult http://www.shure.com for tips and best practices for remote mounting antennas.
RF Output Distribution

The RF outputs distribute the signal from a pair of antennas to up to 4
receivers or additional antenna distribution systems. Port-to-port isolation
reduces interference, making the distribution ports the best option for dis-
tributing signal to additional devices.
Connecting Devices
Connect an A and B pair of RF outputs from the Antenna System to the A
and B inputs of the device.

Input Band Filtering
The input band filters act on the RF distribution ports but do not affect the
RF cascade ports. The Wideband setting passes 470-698 MHz (AXT630)
or 606-814 MHz (AXT631). Select the band filter that most closely matches
the tuning range of connected devices to optimize performance.
When a Band filter has been set, operate and tune connected devices
within the selected band.
Gain and Attenuation
Use the RF Gain menu to maintain consistent signal levels sent to con-
nected devices. The available adjustment range is -12 to +3 dB when the
Cascade ports are off and -15 to 0 dB when the cascade ports are active.

The RF cascade ports extend the Antenna Distribution System by providing
a connection point for additional receivers, Spectrum Managers, or Antenna
Distribution Systems.
When Antenna Cascade is set to Auto, the Cascade ports automatically
activate when 12 V DC from the antenna input of a connected device is
sensed at the port connection. When the cascade ports are active, a signal
splitting loss occurs of 5 dB (max.).
Receivers with RF cascade outputs can extend the antenna signal to addi-
tional receivers within the same band.
Adding an AXT600 Spectrum Manager to an
Antenna System
Connect the AXT600 Spectrum Manager to the RF Cascade ports of an
AXT630 or AXT631.
