TMA TWIN 1800/2100/2600 WITH L-BAND BYPASS
Designed to be deployed in collocated 1800, 2100, 2600 and L band systems, the Kaelus MI-185 enhances cell uplink coverage in 1800, 2100 and 2600 through improved system noise figure, thereby saving operational and capital expenditure.
FEATURES
- Improved base station sensitivity through gain in the 1800, 2100 and 2600 uplink
- L-Band bypass
- Internal diplexing: 2 Antenna ports
- Excellent noise figure performance
- Full AISG operation and RET antenna support, AISG2.0 compatible
- Small and light for minimum visual impact
