• Hybrid Combiner. MTS 2 can have either a Hybrid Combiner for transmission on one antenna, or without
combining for transmission on two separate antennas.
MTS 2 is equipped with a digital voltage standing wave ratio (VSWR) monitor to ensure site availability at remote
low-traffic sites and for public safety customers. The digital VSWR monitor can make a quite accurate VSWR
reading because the measurement is relative between the forward and reverse power.
The VSWR monitor does not have the same accuracy in power reading as the digital power monitor (DPM) in the
MTS 4, but it still allows a cost-effective monitoring of the integrity of the antenna.

MTS LiTE and MTS 2 Filter Tray

The MTS LiTE filter tray can carry one Duplexer and one Preselector or one Duplexer and no Preselector. The
antenna connectors from the Duplexer extend from the MTS LiTE junction panel while antenna connection from the
Preselector is connected via the use of cable. Antenna cables are connected directly onto the filters.
Note:
In Table 71: MTS LiTE RF Configurations on page
Power is valid for 400 MHz, 800MHz and 900 MHz. The numbers illustrated are applicable for TETRA.
The MTS 2 filter tray can carry up to two Duplexers and one Preselector or one Duplexer and two Preselectors. There
is also room for a Hybrid Combiner. The antenna connectors extend from the MTS 2 junction panel and antenna
cables are connected directly onto the filters.
Note: In
MHz, while High Power is valid for 400 MHz, 800MHz and 900 MHz. The numbers illustrated are
applicable for TETRA with TEDS numbers within parentheses.

Note:
MTS LiTE supports one Duplexer.
Because the MTS 2 has only up to two carriers, there is no need for Post Filters for non-duplexed
operation (you can achieve non-duplexed operation by using the Duplexer as the Post Filter and not
using the receive path of the Duplexer).
