TMA TWIN 1800/2600
Designed to be deployed in collocated 1800 and 2600 systems, the Kaelus MI-149 enhances cell uplink coverage in 1800 and 2600 through improved system noise figure, thereby saving operational and capital expenditure.
FEATURES
- Improved base station sensitivity through gain in the 1800 and 2600 uplink
- Internal diplexing on the antenna port of 1800,2600 bands: 2 Antenna ports
- Excellent noise figure performance
- Full AISG operation and RET antenna support, AISG2.0 compatible
- Small and light for minimum visual impact
