Appendix F. ODU Installation
The ODU comprises the antenna with feed-horn and mounting structure, and a transceiver that contains
the LNB integrated with OMT, TX-reject filter, and the transmitter (BUC). If the STM SatLink
4033/4035 transceiver is not used, the OMT, LNB and BUC may be supplied as two or three separate
units. Two cables with F-connectors, one for TX and one for RX are connecting the ODU to the IDU.
