The M101-150-8TRM19 uses up to eight (8) 10 in, high "Q" low loss cavities mounted on a standard 19 in x 72 in rack. This combiner provides as much as 75 dB isolation for each transmitter, with spacing as close as 105 kHz. Each channel has a separate isolator with 60 W load (standard) and all tuning is accessible from the front panel. With new narrowband channel assignments, proper filtering is even more critical. The M101-150-TRM19 series allows operators of high-density VHF systems to take advantage of new technology and enhance the performance of existing systems.
