TMA TWIN 800/900 MHZ
Designed to be deployed in collocated 800 and 900 systems, the Kaelus MI-146 enhances cell uplink coverage in 800 and 900 through improved system noise figure, thereby saving operational and capital expenditure.
FEATURES
- Improved base station sensitivity through gain in the 800, 900 uplink
- Excellent noise figure performance
- Full AISG operation and RET antenna support, AISG2.0 compatible
- Small and light for minimum visual impact
