PARAMETER SPECIFICATION REMARKS
Physical/Electrical – DRU
Weight 1.5 lbs (708 g)
RF connection SMA Female
Antenna types Ceiling mount omni directional
90º directional panel
Ceiling mount hallway
2.5 dBi gain
7.5 dBi gain
4 dBi gain
Optical connection Duplex LC transceiver
DC pwr input connection RJ-45 Female
Power input 34 to 48 VDC
DC power cable length
(Cat-3 or -5 cable)
500 meters (1,641 ft) maximum Any distance beyond 500 meters
requires alternate power sourcing
Power consumption 19 W Typical
Current rating 400 mA at 48 VDC
Note: The noise from all remotes is added at the host. Given N units with identical gain and noise, the formula
applies exactly. Slight unit to unit noise figure and gain variations make this a very useful approximation.

Note : Per Industry Canada Section 5.3 – The rated output power of this equipment is for single carrier
operation. For situations where multiple carrier operation signals are present, the rating would have to be
reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to
adjacent band users. This power reduction is to be by means of input power or gain reduction and not by
an attenuator at the output of the device.
