DADM224-MK2
Protect the receivers against unwanted
interfering RF signal with the filtered design.
The DADM224-MK2 is a custom design that offers the solution to antenna distribution requirements for portable sound bags.
A unique custom design Antenna 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 individually.
The DADM224-MK2 is a custom tuned filtered antenna distribution design for Diversity receiving system operating in the frequency range from 470 – 1164MHz(in bands). User adjustable system gain in 1dB steps to suit varying applications and suitable with all types of modulation techniques in the industry.
Uses industry standard connectors, 2 x BNC as Antenna inputs and 2x4 SMA Antenna output connectors with active antenna powering. DADM224-MK2 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.
