MI-146

MI-146

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.

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 800, 900 uplink
  • Internal diplexing on the antenna port of 800,900 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
