CHAPTER 3
INSTALLATION
3-1 INTRODUCTION
This chapter provides instructions for installation of the Cabin Access Point (CAP). After
configuring the CAP as described in the operating software operator’s manual, use the instructions
provided in this chapter to install the CAP. Installation of the CAP must be performed by personnel
authorized to perform maintenance on the aircraft.
3-2 MOUNTING
3-2.1 CAP Unit
Six mounting holes are provided on the CAP. Figure 3-1 shows the CAP outline dimensions and
mounting-hole locations. Mount the CAP using number 10 mounting hardware. Although not
mandatory for specification compliance, it is recommended that the CAP unit be mounted to a
grounded surface within the aircraft. An unpainted area around each mounting hole provides ground
connection to the mounting surface.
3-2.2 Indoor Cabin Antenna
Two antennas are required for each CAP unit configured as a cabin wireless LAN unit (CWLU).
Two mounting holes are provided on antenna part numbers 901167-1 and 901167-2. The antenna is
fitted with a 7.25-inch cable that connects to the CAP RF output connector. Figure 3-2 shows the
outline dimensions and mounting-hole locations for the antenna. The radiation pattern for antenna
part number 901167-1 is shown in Figure 3-3. The radiation pattern for antenna part number
901167-2 is shown in
Figure 3-4. Mount the antenna using number 6 mounting hardware. It is
recommended that the antennas be mounted a minimum of six inches apart. Contact W. L. Gore &
Associates, 402 Vieve’s Way, Elkton, MD 21921, 800-311-3060, www.gore.com for installation
information for leaky line antenna, Gore part number GSC10-82701-XX.
3-2.3 Outdoor Antenna
An antenna mounted on the exterior of the aircraft is required for a CAP unit configured as a
terminal wireless LAN unit (TWLU). The antenna is fitted with TNC female connector(s). Use a
TNC Male-to-TNC Male 50-ohm coaxial cable to connect the antenna to the CAP unit.
Figure 3-5
shows the outline dimensions and mounting hole locations for antenna part number 901058-1
(IEEE 802.11b/g operation).
Figure 3-6 shows the radiation patters. Figure 3-7 shows the outline
dimensions and mounting hole locations for antenna part number 901563-2 (IEEE 802.11a and
IEEE 802.11b/g operation).
Figure 3-8 shows the radiation patterns. Mount the antenna using
number 10 mounting hardware.
