HGA-6000 High Gain Antenna
Installation Manual
4.1.2 General Electrical Requirements
1) The minimum wire size for power lines is #22AWG. Where workmanship standards allow,
#24AWG may be used for all other lines. The installer is however responsible for determining
the appropriate wire size required for the length of cable run, to ensure that the specified
maximum cable losses do not exceed those indicated in this manual.
2) Keep the interconnect cables away from circuits carrying heavy current, pulse transmitting
equipment and any other potential source of interference.
3) Use shielded twisted-pair wiring for all balanced connections. Shields should be grounded.
4) The characteristic impedance of each coaxial cable (connectors included) should be 50 Ohms
with a VSWR of less than 1.2:1
4.1.3 Summarized Installation Tasks in Sequence
HGA-6000 installation tasks
Step 1)
The HGA-6000 will typically be mounted in the aircraft's tail radome. A suitable
mounting plate or structure will be required to interface with the four mounting holes in
the HGA-6000 base and must be supplied by the installer.
Step 2)
Determine or measure the HGA-6000 alignment angles prior to mounting the HGA-6000.
See section 4.2.2.2.
Step 3)
Mount the HGA-6000.
Final testing
Step 4)
If using a non-Cobham SDU, run the Antenna Systems Support software (see Appendix
B). Installation angles are now entered. If using a Cobham SDU, then the install angles
may be stored in the SDU. Refer to the Swift64 or SwiftBroadband SDU installation
manuals.
Step 5)
Complete the connection of the HGA-6000 to the Swift64 or SwiftBroadband system.
