Description

Overview

The Diversity Antenna Distribution Module DADM226-DT mk II offers antenna and DC power distribution, as well as interference protection, in a small form factor designed to fit in a sound bag. It offers user selectable narrow RF-Bandwidth with high selectivity RF filters to suit individual applications and frequency allocations.

The P Model adds additional filters, a wideband mode and various other options:

Size	7.01" x 1.38" x 2.21" (178 x 35 x 56 mm)	7.28" x 1.38" x 2.21" (185 x 35 x 56 mm)
Weight	13.05 oz (370 g)	13.93 oz (395 g)

The filters are individually digitally tuned in the frequency range 470-702MHz and are user selectable in 8MHz step, 24MHz bandwidth with adjustable gain between +10dB to -10dB, user adjustable in 1dB steps.

The DADM226-DT mk II is an active antenna distribution system with user-selectable narrow-bandwidth band-pass filtering to eliminate multiple receiver antennas and provides a tidy solution for sound bags, carts, and trolleys with improved RF performance.

There are two industry standard BNC input connectors for antenna inputs and 2 x 6 mini-RF SMA connectors feeding the diversity receivers.

In applications requiring remote antenna powering, the DADM offers switchable active antenna powering. The power can be activated through the OLED display menu.

The DADM226-DT mk II has an extremely high input signal handling capacity with an extremely low noise figure and offers outstanding intermodulation performance

A standard 4-pin Hirose connector is used for DC power. An additional Hirose DC connector (HR2) is user configurable as DC IN or DC OUT through the OLED menu.
