MI-180

TMA TWIN 1800/2100/2600

Designed to be deployed in co-located Low band, 1800, 2100 and 2600MHz systems with wideband antennas, this Tower Mounted Amplifier provides gain in all of the high bands.

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 1800, 2100 and 2600 uplink
  • Internal diplexing on the high band port of 180 and 2100: 4 Antenna ports
  • Excellent noise figure performance
  • Full AISG operation and RET antenna support, AISG2.0 compatible
  • Small and light for minimum visual impact
