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:

  • 470-608MHz
  • 470-663MHz
  • 470-700MHz
  • 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.
