The Manufacturer's rated output power of this equipment is for single carrier operation. For
situations when multiple carrier 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.
The 5BARz™ Road Warrior has internal gain control that ensures that the output power will not
exceed the requirements as specified in the paragraph above.
Antenna Requirements
This device has been designed to operate with the antennas listed below, and having a maximum
gain as shown in the chart below specifying maximum allowed antenna gains. Antennas not
included in this list or having a gain greater than the listed gains are strictly prohibited for use
with this device. The required antenna impedance is 50 Ohms.
