Installing the IFL cables
Before you can point the antenna, you must route the IFL cables between the indoor satellite modem location and the
antenna. Then you connect the modem and the antenna by connecting the IFL cable to both components.
(See also Requirements for IFL cables, connectors, and ground blocks on page 11.)
Routing and connecting the IFL cables
To point the antenna, you must connect the modem to the antenna and install the DAPT (a Hughes tool that displays
antenna pointing values.)
1. Route the IFL cables from the indoor satellite modem location to the antenna.
The routing path depends on the building configuration. Guidelines for installing IFL cables are included in the
Antenna Site Preparation and Mount Installation Guide (1035678-0001).
2.
Connect the transmit IFL cable to the transmit connector on the radio transmitter.
(The transmit cable is not shown in
Figure 17: In-line connection of the DAPT on page 28.)
3. Connect the receive IFL cable to the DAPT, as shown in Figure 17: In-line connection of the DAPT on page 28.
Figure 17: In-line connection of the DAPT
For additional information on pointing and the DAPT, see the Ka-Band Antenna Pointing Guide (1037663-0001).
4. Use a temporary cable to connect the DAPT to the LNB on the radio assembly as shown in Figure 17: In-line
connection of the DAPT on page 28.
This is a temporary arrangement that is required for antenna pointing.
Note: The connectors on the DAPT are labeled IDU and LNB. If the cable from the satellite modem (the IDU)
and the cable from the radio assembly on the antenna are connected to the wrong connectors, the DAPT will
not receive a signal.
IFL grounding requirement
The coaxial IFL cables and the ground block to which they are connected must meet the grounding requirements specified
in the following warning:
You must comply with applicable local codes and the grounding requirements in Field Service Bulletin (FSB),
HNS
Broadband Requirements for RG-6 and RG-11 IFL Cable Connectors, Ground Blocks, and Ground Block Location
(FSB_050518_01). Improper grounding can result in electric shock injury and/or property damage.
