ACM0008F2V1-1

SAME BAND COMBINER, 900 TYPE 1 PASSIVE

The Kaelus ACM0008 is a passive combiner used to combine two 900MHz base stations to a single feeder with minimal downlink (TX) Insertion loss. Normally used in conjunction with the Kaelus 900MHz TMA this combiner saves the operator capital and operational expenditure by minimising the number of feeders required.
