Two Separate Duplex Antennas

If two separate duplex antennas are already in use, the recommendation

is to install new antennas for dTRU based RBS and not use co-siting at

One RX and One Duplex Antenna

If the original antenna arrangement is TX/RX + RX, the

recommendation differs for conﬁgurations where the duplex ﬁlter is

mounted internally, without the possibility to access the TX and RX

ports separately, and conﬁgurations where the RX path is accessible.

Internal Duplex Filter

If the duplex ﬁlter is internal and the RX path is not accessible, the

recommendation is to add one antenna and rebuild the conﬁguration in

the same way as in the case with TX + RX + RX in Section 4.8.1 on

Two separate duplex antennas

Recommendation:

No Co-siting!
