The RFI RDA9-61 is a ruggedised 9-element Yagi antenna designed for high-gain directional communication in the 450-480 MHz frequency range. Built specifically for extreme and hostile environments, this antenna features a robust construction with larger elements and boom than standard Yagi models. Its all-welded design and black powder-coated finish ensure long-term durability, minimal interference, and reliable performance in challenging conditions.

Product Features:

• The RFI RDA9-61 antenna is constructed with all elements, including the feed, fully welded to the boom for maximum strength and minimal intermodulation.
• This 9-element Yagi design delivers 13 dBi gain, making it ideal for long-range, high-performance RF communication.
• The feed element is a full folded dipole, offering maximum bandwidth and consistent signal reliability.
• The ruggedised boom and element structure are significantly more robust than standard YB series antennas, ensuring durability in extreme conditions.
• The black powder coating enhances resistance to environmental wear and aids in snow and ice shedding by maximizing solar heat retention.
• The antenna can be configured in stacked or bayed arrays using PH and PHE series phasing harnesses for higher gain applications.
• It is designed to rest at DC ground potential, providing excellent lightning protection and reduced precipitation static noise.
• Termination is via an N female coaxial connector fitted to a short Durathene cable tail, which offers superior resistance to weathering and abrasion and is less susceptible to bird damage.
• The antenna is also available in an unpainted, plain alodined aluminium finish by specifying the“RDB"prefix when ordering.

Application Areas:

• The antenna is ideal for point-to-point communication in extreme climatic and high-vibration environments.
• This antenna is suitable for RF control, telemetry, and long-haul directional communication systems.
• It is designed for use in industrial, remote, or outdoor installations where durability and minimal interference are essential.
