The RFI RDA3-99 is a 3-element ruggedised Yagi antenna designed for high-gain directional communication across the 300-600 MHz frequency range. Built for extreme climatic environments, this antenna features a robust construction with enhanced durability and performance, making it ideal for mission-critical RF applications in harsh conditions.

Product Features:

• The antenna is constructed with significantly larger and more robust elements and boom compared to standard YB models, ensuring durability in extreme environments.
• It operates across the 300-600 MHz frequency range and is factory tuned to a custom frequency with a 4% tuned bandwidth.
• It delivers 8 dBi gain with a narrow beamwidth and high front-to-back ratio, effectively reducing interference to and from other systems.
• The all-welded construction ensures maximum reliability and long-term performance in demanding conditions.
• The black powder-coated finish aids in snow and ice shedding by maximizing solar heat retention.
• It includes DC grounding on all elements for superior lightning protection and static noise dissipation.
• The antenna can be configured in stacks or bays using PH and PHE series phasing harnesses for higher gain applications.
• Termination is via an N female connector fitted to a short Durathene cable tail, offering excellent resistance to weathering, abrasion, and bird damage.

Application Areas:

• The antenna is ideal for point-to-point RF communication in extreme climatic environments.
• This model is suitable for RF control and telemetry systems requiring rugged, high-performance antennas.
• It is a dependable solution for installations where high directionality and low interference are critical.
• The design supports use in both horizontal and vertical polarization systems.
