APPENDIX B
— POSSIBLE RF ANTENNA CONFIGURATIONS
The ITC 220 Base Station Transceiver allows for three possible RF antenna configurations.
Single-antenna configuration
The antenna is connected to the primary receive port, which is the TX/RX port. Terminate the other two ports, RX1
and RX2 each with 50 Ohm termination.
Two-antenna configuration
One antenna is connected to the primary receive port, which is the TX/RX port. A second antenna is connected to
the diversity port, RX2. Terminate the remaining port, RX1, which is unused, with 50 Ohm termination.
Three-antenna configuration
One antenna is connected to the primary receive port, which in this configuration is RX1. A second antenna is
connected to the TX/RX port. A third antenna is connected to the diversity port, RX2.
