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 WinLink 1000 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 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.

Various external antennas are available for the WinLink 1000 operating frequencies.
Flat Panel Antennas
The Flat Panel antenna shown in Figure 1-23 is available as an
integrated or external antenna. Flat panel antennas are suitable for
short range, typically in Access applications. They are relatively
cheap, use comparatively little tower space and are robust under
extreme weather conditions.
