The PoE-8 can only be used with FA4800 radios.
Antennas
An antenna is the radiating and receiving element from which the radio signal, in the form of
RF power, is radiated to its surroundings and vice versa. The antenna gain and transmitting
power may be limited by country regulations.
The FA4800 may be operated with an integrated antenna that is part of the ODU unit, or with
external antennas connected to the ODU via N-type connectors. All cables and connections
must be connected correctly to reduce RF losses. The required antenna impedance is 50.
The 5.x GHz Integrated Antenna ODU is provided with 330 mm (1ft) flat panel antenna, with
a gain of 22dBi (5.x GHz) / 17dBi (4.9 GHz) and 9° beam width. The 2.x GHz Integrated
Antenna ODU is provided with 330 mm (1ft) flat panel antenna, with a gain of 16dBi and 20°
beam width. The radio and the antenna are housed in a weatherproof case as a single unit.
