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 RADWIN 2000 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 con-
nections must be connected correctly to reduce RF losses. The required antenna impedance
is 50Ω.
The 5.x GHz Integrated Antenna ODU is provided with 370 mm (1.2ft) flat panel antenna,
with a gain of 23dBi (5.x GHz) / 19dBi (4.9 GHz) and 8° beam width. The 2.x GHz Integrated
Antenna ODU is provided with 370 mm (1.2ft) flat panel antenna, with a gain of 16dBi and
16° beam width. The radio and the antenna are housed in a weatherproof case as a single
unit.

External antennas are available for the RADWIN 2000 radios, varying in operating frequen-
cies, form factor, size and gain, dual or single polarization.
The Flat Panel antenna shown below can be used either as an integrated or external antenna.
