Preliminary
9. Reattach the cable assemblies from the ports labelled “Tx” and “Rx” on the RFC, and the
ports labelled “J1” and “J2” on the diplexer. Cable connections should be aligned to each
other as follows:
Plan A Plan B
Tx = 2422 Tx = 2462
Rx = 2462 Rx = 2422
10. Replace and secure the RFC cover.
For mastmounted systems, do the following to reconfigure the RFC interconnect:
1. Remove the lid of the mast RFC.
2. Disconnect the three cables attached to the diplexer. The diplexer may be identified by
following the antenna connector to the middle connector of the diplexer. Leave the cables in
the same positions.
3. Remove the two screws securing the diplexer and rotate the diplexer to reveal the opposite
frequency plan label.
4. Reinstall the two screws and reattach the cables in the same positions.
5. Reinstall the lid of the mast RFC.

MODELS
The 5.8 GHz RFC operates on Plan A, Tx = 5747 MHz, Rx = 5827 MHz or Plan B, Tx = 5827 MHz,
Rx = 5747 MHz. See
Figure 2-2 for an illustration of the 5.8 GHz diplexer.
