RF filtering protects the receivers against interfering signal and unwanted dirty RF, maintains continuous RF reception in Diversity operations.

The AD224-P is a 2-IN and 2x4 OUT active antenna distribution system with custom tuned high selectivity front-end exceptionally low insertion loss band-pass filters.

The AD224 eliminates multiple receiver antennas and provides a tidy sound bag solution with improved RF performance. Advanced filtering design cleans up dirty RF within the operating bandwidth before feeding into the Diversity Receivers this is important in crowded radio frequency spectrum to protect the receivers from unwanted RF signals.

The AD224 is a custom designed Antenna Distribution (AD) system offers the solution to the antenna and dc power distribution requirements for portable sound bag applications. Designed for where the weight and size matters without sacrificing on performance.

The antenna inputs are BNC connectors which enables use of standard low loss RF coaxial extension cables, and the outputs are 2x4 mini-RF SMA connectors feeding the diversity receivers.

In applications when remote active antenna powering is needed the AD offers switchable Active Antenna Powering with RED LEDs indicating power ON/OFF status, the Active Antenna Powering can be turned ON/OFF through the high visibility large display menu.

The DA224-P has an extremely high input signal handling capacity with exceptionally low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available.

The tuning bandwidth is custom tuned with a semi broadband response to suit varying applications, the system RF gain is user adjustable in 1dB steps between +6dB to -10dB, the DA224-P is compatible with full-digital, digital-hybrid and analogue radio microphone receivers available in the industry.

The DA unit is externally powered between 10-18Vdc, the dc input connector is an industry standard 4-pin Hirose and there are 4xHirose dc output connectors available for powering auxiliary equipment. Each dc output port can be individually turned ON/OFF through the display menu. The inbuilt Voltmeter continuously displays dc input voltage status.
