4-WAY Diversity Antenna Distribution Module -DADM224-MK2-P (IN STOCK) from
DADM224-MK2-P
Protect the receivers against unwanted
interfering RF signal with the filtered design.
The DADM224-MK2-P is a custom design that offers the solution to antenna and power distribution requirements for portable sound bags.
A unique custom design for Antenna and DC Power Distribution system offers excellent rejection for interference-free operation feeding up to four Diversity Receivers.
User-adjustable settings can be controlled via the intuitive OLED display menu to set system RF Gain, powering active antennas, soft ON/OFF switching to turn each Hirose dc output individually.
The DADM224-MK2-P is a custom tuned filtered antenna distribution design for Diversity receiving system operating in the frequency range from 470 – 675MHz(in bands). User adjustable system gain in 1dB steps to suit varying applications and type of modulation techniques.
Uses industry standard connectors, 2 x BNC as Antenna inputs and 2 x 4 SMA Antenna output connectors with active antenna powering. The four switchable DC Hirose power sockets supply dc power to sound bag or sound cart equipment. DADM224-MK2-P is a custom design, CNC machined aluminum box to withstand daily location work, finished in black anodizing with clear laser marked legends for long-term readability.
