TMA2142 | MI-191

TWIN TMA 1800/2100/2600 Low-band BYPASS

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. The MI-191 and the TMA2142 are the same product but to ease the transition for our customers both Kaelus and Microdata part numbers will be maintained.

MI-191: part number under Microdata brand
TMA2142: part number under Kaelus brand.

Note: in the AISG mode "TWOTWO " the multi band TMA is seen as 2 logic units with 2 subunits each and it is only required to connect to one of the two BTS ports. Either port can be used.

Note: in the AISG mode "TRITWO " the multi band TMA is seen as 3 logic units with 2 subunits each and it is only required to connect to one of the two BTS ports. Either port can be used.
