4.2.1 Terminating the RF Connector
Before applying power, if using the external antenna version, the device’s RF connector(s) must
be properly terminated into a 50-ohm load. If this is not performed, the radio may be damaged by
simply applying power. Also, for both the integrated and external antenna versions, there are
human safety factors to consider regarding potentially harmful RF radiation.
There are a few simple means to accommodate this proper termination:
• Connect a 50-ohm coaxial termination device to the RF port of the radio. The termination
needs to be rated to 1W (or more). Example(s) include:
o Broadwave Technologies P/N 552-200-002, or similar
• Connect the complete transmission system. That is, the RF cabling including the antenna.
The cabled antenna provides a proper termination for the RF output.
• Connect a fixed (or a series of fixed) 50-ohm attenuator(s) to the RF connector, either
directly or at the end of an RF transmission line. The attenuator should be at least 30dB
as specified between 5250 and 5850 MHz, and rated for a minimum of 0.5W input
power. Examples include:
o Broadwave Technologies P/N 352-103-xxx
o Bird 2-A-MFN-xx
o JFW Industries 50FP-xxx-H6-N
4.2.2 AC Power
The AC adaptor comes equipped for easy direct connection to the power injector. The AC rating
of the adapter accepts most worldwide standard voltages and frequencies. Please refer to the
input voltage requirements stated on the label that is affixed to the adapter to assure that the
adapter may be used with your AC mains supply. The AC plug outlet provided with the adapter
may need to be replaced to match your country configuration. The adapter cable uses a standard
connector for this cable so that you can simply use a pre-wired cable that is appropriate to your
outlet configuration. If that type of cable is not available, the existing AC plug end can be
severed and a replacement plug affixed. Consult a qualified electrician for this activity.
Do not plug the adapter into your mains power. First, verify that the RF connector is properly
terminated (per section 4.2.1 above). Next, connect the supplied CAT5 cable between the
Power/Ethernet connector on the radio and the Data+Power connector of the power injector.
Now plug in the injector-side connector from the AC adapter to the injector. If your AC mains
can be turned off by a switch, disable the power first, plug the AC side of the adapter into the AC
mains socket, and then enable power to the circuit. If your AC mains cannot be turned off,
simply plug into the AC main socket to apply power. Verify that the radio is active by observing
LED activity. All LEDs on the radio will flash at initial power cycle, for the user to verify that all
LEDs are operational.
It is strongly encouraged that the AC Mains supply be fused or on a breaker to ensure against
over-voltage and/or over-current situations to provide some form of protection to the radio
electronics and other devices that may be connected to the same supply. In addition, if your AC
power is subject to significant spikes or variation, power conditioning is a worthwhile
