TECHNICAL INSTRUCTIONS

Section 2 PREPARATION FOR USE AND INSTALLATION

2.1 INTRODUCTION

This section contains the installation
information for the antenna. Nautel
recommends that all requirements be
incorporated to ensure optimum reliability
and performance.

NOTE

Failure to comply with these
recommendations and instructions could
void the manufacturer’s warranty. Please
review Nautel’s warranty terms for more
information.

2.2 ANTENNA PATH SELECTION

Consider the following during layout
planning (i.e., before installing the
antenna):

• Avoid excessive capacitance
between the antenna and adjacent
structural components by maximizing
their separation.

• Ensure all RF conductors (antenna
wire and ATU to antenna connection)
are out of the reach of personnel.

• Ensure antenna will not interfere with
any machine operations (e.g., crane).

• Location of transmitter and ATU
mounting.

2.3 ANTENNA SUPPORT

MOUNTING

Consider the following when determining
where to install the antenna supports:

• Antenna support poles are to be
secured to the top side of the helideck
safety net support posts.

• The antenna can be mounted without
one or both start/end support pipes if
there is an adjacent structure suitable
to fasten the Insulator (item 11) to,
horizontally. Two additional End Bond
Leads (item 10), which have lugs
crimped on one end, have been
included to bond the base of the
Insulator to the adjacent structure.

• Locate antenna supports at antenna
start/end and platform corners

NOTE

The number of corner supports depends
on the shape of the helideck platform. See
Figures 2-1a and 2-1b for an example of
corner antenna supports.

• On helidecks with less than 25 ft.
(7.6 m) between corner-installed
antenna supports, no additional
antenna supports are required.

• On helidecks with greater than 25 ft.
between corner-installed antenna
supports, add one additional antenna
support between the corners.

Figures 2-1a and 2-1b illustrate two
different layouts of the CL-HD antenna.
Figure 2-1a shows an end feed antenna.
Figure 2-1b shows a centre fed antenna.

NOTE

It may not be necessary to use all antenna
supports supplied with the antenna. Any
unused supports and insulators should be
stored for replacement use.
