2.2.5 RF Coaxial Transmission Line - Pre-installation Requirements
This section contains pre-installation information applicable to the use of Nautel supplied
transmission line kits (box-line and rigid line) for each transmitter system. The following
information is relevant to all of the systems covered by this handbook except where noted.

Appendix A

Appendix F
(a)
Ensure that sufficient space is made available for the assembly and installation of site
specific rigid line and box-line sections, as applicable.
(b)
Prepare a suitable hole in the wall to support the RF output bushing box, provided by
Nautel. See the System Layout Drawings in Appendix A and Figure 2-5 for details.
(c)
Build support structures for the transmission line sections, which should be ready for use
during installation. See the Layout drawing in Appendix A and Figure 2-5 for weights,
dimensions and height requirements, noting:

6-1/8-inch or 3-1/8-inch rigid line (transmitter to IMU) is 10 kg (22 lbs)/m

Box-line: (various connections see Figures 2-5) 4.5 kg (10 lbs) per 1.2 m (4 ft)
sections. Elbow sections are also 4.5 kg (10 lbs) per section.
NOTE
Plan the installation of your transmission line system according to the system layout drawings
provided. The position and height of system components such as the transmitters, IMU,
4-port switch and RF output bushing box are critical in determining the height of transmission
line support structures.
(d)
Make sure a set of standard hand tools is available to perform transmission line
installation.
