Antenna Distribution Systems send the RF signal from a single pair of antennas to multiple receivers. Ultra-linear amplification and adjustable attenuation optimize performance in difficult RF environments. Selectable input filters match the available frequency bands of transmitters, providing extra protection from strong out-of-band signals. BNC antenna output pairs distribute band-filtered signals to up to 4 receivers. A pair of wideband cascade ports supply wideband RF signals to Spectrum Managers or additional antenna distribution amplifiers. Networking allows Wireless Workbench to control filtering ranges and attenuation. For added flexibility, Axient Antenna Distribution Systems are compatible with Shure ULX-D and UHF-R receivers.
To maximize use of the RF spectrum, Antenna Distribution Systems are available in the following frequency ranges:
Note: Instructions in this system guide apply all models of Axient Antenna Distributions Systems.

The Antenna Distribution Systems are compatible with front-mounted antennas or with remote-mounted antennas.
Note: When using the input band filtering function, select an antenna with bandwidth to cover the filter range.
Mounting the antennas on the front panel improves system performance by providing a clear signal path for the RF signal. Use the supplied bulkhead adapter kit to install the antennas on the front panel.
Note: To minimize the possibility of signal dropout and optimize performance, point the antennas up and away from each other at 45° from vertical.
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 distributing signal to additional devices.
Connect an A and B pair of RF outputs from the Antenna System to the A and B inputs of the device.
The input band filters act on the RF distribution ports but do not affect the RF cascade ports. The Wideband setting passes the full frequency range of the Antenna Distribution System. 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.
Use the RF Gain menu to maintain consistent signal levels sent to connected 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 additional receivers within the same band.
Connect the AXT600 Spectrum Manager to the RF Cascade ports of the Antenna Distribution System.
For large configurations, multiple Antenna Distribution Systems can be layered to support several levels of signal distribution:
Level 1: Antenna Distribution System set to Wideband
Level 2: Antenna Distribution System set to a band filter matching the 4 receivers tuned to the same band
Connect the AXT600 Spectrum Manager to the RF cascade ports of the Level 1 Antenna Distribution System
The antenna input status LED flashes red to indicate a short or over-current condition at an antenna port. To isolate the fault, navigate to the DC power menu. The menu displays which antenna port (A, B, or A+B) is the source of the fault. Check the antenna connections to remove the fault condition.
The Over Temperature message is displayed when the fans are unable to cool efficiently, indicating an elevated temperature condition.
Use the main menu to select the band filter, adjust the RF gain, and configure the antenna ports.
Selecting an input Band filter optimizes performance when the components connected to the RF outputs are all within the same band. The selected band filter will only pass frequencies within the range of the connected components. Four selectable input filters are available to match the frequency bands transmitters and receivers. A Wideband setting is available to extend frequency support across all 4 bands. This setting allows receivers operating in a variety of bands to use the RF outputs.
To set the Band filter:
Adjust the RF gain to boost or attenuate the antenna signal to maintain consistent levels and prevent overload. Gain adjustments are made in 1 dB increments.
The gain adjustment range depends on the connection status of the RF cascade ports:
Auto |
The ports will activate when a connected device supplies 12-15 V DC to the port. |
On |
The ports are continuously active, independent of voltage applied by a connected device. |
ON |
The antenna ports supply 12-15 V DC to power active antennas. |
OFF |
Turns off DC voltage at the antenna ports. |
Active |
Indicates connectivity with other devices on the network. |
Inactive |
No connectivity with other devices on the network. |
