The TDMA RBS may be equipped with only one TX/RX antenna. The
recommendation in this case is to add two antennas for the dTRU based RBS.
One RX signal from the dTRU based RBS is supplied to the TDMA RBS, thus
adding RX diversity to the TDMA RBS.

If two separate duplex antennas are already in use, the recommendation is to
install new antennas for the dTRU based RBS and not use co-siting at all.
