2.3.2 RF IN Connector
Up to four RF inputs connect the L-band output of a
suitable Low-Noise Block down-converter (LNB) to the
unit either directly or via a suitable attenuator. The RF
inputs may also be used to supply DC power to the LNB,
if required.
Cautions!
The receiver provides DC power via the active L-band input connector to drive an
LNB. Do not connect equipment other than an LNB to this connector. Failure to do
this may result in damage to the external equipment.
The F-type connector is not suitable for repeated connection and disconnection.
When intended for use in this way, fit a sacrificial connector and connect to it.
