TMA TWIN 1800/2100
Designed to be deployed in collocated 1800, 2100 systems, the Kaelus MI-143 enhances cell uplink coverage in 1800, 2100 through improved system noise figure, thereby saving operational and capital expenditure.
FEATURES
- Improved base station sensitivity through gain in the 1800, 2100 uplink
- Internal diplexing on the high band port of 1800,2100 bands: 4 Antenna ports
- Excellent noise figure performance
- Full AISG operation and RET antenna support, AISG2.0 compatible
- Small and light for minimum visual impact
