DADM224-MK2
Protect your receivers against unwanted
interfering RF signal with the filtered design.
The DADM224-MK2 is a custom design with a highly selective Band-Pass Filter at the input to reject unwanted, dirty RF signals and only pass signals withing the custom tuned filter bandwidth, ideal for portable sound bags, cart and trolley applications.
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, available frequency bands:
- 470-700MHz
- 470-608MHz
- 470-663MHz
- 470-960MHz
RF GAIN:
System RF Gain can be set in 1dB steps to suit individual application
INDUSTRY STANDARD CONNECTORS:
Antenna input uses 2 x BNC and 2x4 SMA Antenna output connectors with active antenna powering on demand.
CUSTOM DESIGN:
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.
