The GSU is connected to the HSS Unit using a standard HSS cable. It synchronizes the trans-
mission timing of multiple Hub-Sites to the same clock source thus eliminating mutual inter-
ference (see
Chapter 11 ).

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 50
Ω .
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.
