MI-143
MI-143
The Kaelus MI-143 is designed for deployment in collocated 1800 and 2100 systems, enhancing cell uplink coverage through improved system noise figure. This results in operational and capital expenditure savings. The product features improved base station sensitivity, internal diplexing, excellent noise figure performance, and full AISG operation with RET antenna support.
