AeroComm announces a new distribution antenna interface, Model 50289-DAI for frequency bands from FM broadcast (88 to 108 MHz) to PCS (1800 to 2000 MHz). The interface enables multiple communication devices for radiating systems and offers the capability of providing multiple services, including all municipal operations on a single antenna system with the ability to add bands as their system grows. The DAI is passive, has transmission line filters, and type "N" connector ports. It also features a modular construction in a rugged, field-proven NEMA-4 environmental enclosure, requires no AC power and supports power levels up to 50 W per band. The DAI measures 36" x 30"x 12"and weighs 120 pounds.
