MI-190

TMA TWIN PCS/AWS

Designed to be deployed in collocated PCS and AWS systems, the Kaelus MI-190 enhances cell uplink coverage in PCS and AWS through improved system noise figure, thereby saving operational and capital expenditure.

Microdata Telecom rebranding to Kaelus!
Microdata Telecom and Kaelus have had combined operations since Oct 2019 when Microdata acquired Kaelus. We strongly believe that by operating under one global brand we will clarify our strengthened position in the telecom market and from January 18th 2021, we are unifying the brands to Kaelus.

FEATURES

  • Improved base station sensitivity through gain in the PCS and AWS uplink
  • Internal diplexing on the antenna port of PCS and AWS bands: 2 or 4 Antenna ports(See ordering info)
  • Excellent noise figure performance
  • Full AISG operation and RET antenna support, AISG2.0 compatible
  • Small and light for minimum visual impact
  • Available as a twin or quad configuration
