Before you can point the antenna, you must route the IFL cables between the indoor satellite
router location and the antenna. Then you connect the router and the antenna by connecting the
IFL cable to both components.

Requirements for IFL cables, connectors, and ground blocks
To point the antenna, you must connect the router to the antenna and install the DAPT (a Hughes
tool that displays antenna pointing values).
1. Route the IFL cables from the indoor satellite router 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
3. Connect the receive IFL cable to the DAPT, as shown in
the DAPT
on page 28.
Figure 18: 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 18: In-line connection of the DAPT
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 router (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.
The coaxial IFL cables and the ground block to which they are connected must meet the grounding
requirements specified in the following warning:
