HARDWARE INSTALLATION
The Hyperlan-Pack is made up of two identical and interchangeable subsets,
containing an antenna and a Hyperlan-Pack module
fixed to it. The following
instructions are to be carried out for both subsets.
1.
Fix the HF head to the center of the antenna
A parabolic antenna is used. While installing the HF head it must be oriented
for horizontal or vertical polarization using the small arrow drawn on the tip of
the head. To ensure optimal performance, it is important that both antennas
are polarized the same way.
The HF head is fixed to the back of the antenna with a screw (see picture).

2.
Connect the lightning arrestor to the Hyperlan-Pack module
To protect from lightning, a lightning arrestor must be connected to the ‘Main’
port on the Hyperlan-Pack system. The ‘Aux’ port must be connected to a 50-
ohms, N-type terminator
.
To ensure maximum protection, and to
limit loss in cables and connectors, it is
strongly recommended to connect the
lightning arrestor to the ‘Main’ port of the
Hyperlan-Pack without using intermediary
cables.
Should the system be struck by
lightening, a gas capsule inside the
lightning arrestor will explode and protect
the system. In this event, do remember to
change the gas capsule so that the
system is once again protected.
WARNING: it is important that the
lightning arrestor is grounded using the
provided lug
.
3.
Connect the coaxial cable from the lightning arrestor to the
antenna
The lightning arrestor is connected to the antenna by a 60 cm, coaxial cable
(N-type male towards N-type male).
