Antenna Cable Lengths and Types

The Hughes IDU has an automatic cable calibration feature that determines the dB loss of
the cable. The RF cable that comes standard in the terminal kit is 8 meters long. If a
longer cable is required for the installation, the end-to-end RF loss needs to be <10 dB at
1.6 GHz.
Note: The installer is responsible for choosing the proper type of cable for the length
required in order to meet the <10 dB requirement.

Installing the Antenna

WARNING: Avoid exposure to microwave radiation. Keep a minimum safe
distance of one meter (39 inches) to the side and above the antenna.
WARNING: The antenna cable carries DC power. Always power the IDU down
prior to connecting or disconnecting the antenna cable from either the antenna or the
IDU.
The antenna port is a 50Ω female TNC. This line carries RF, signaling, and DC power for
the antenna.
Keep a clear line-of-sight to the satellite. Preferably, avoid all obstructions within
3 meters of the antenna. Obstructions less than 15 cm (6 inches) in diameter can be
ignored beyond this distance.
