The RFI YBS803-99 is a 3-element stainless steel Yagi antenna custom tuned for broadband directional communication across the 540–1000 MHz frequency range. Built from all-welded 316 grade stainless steel, it offers the same performance as the YB800 series but is specifically designed for extreme climatic and corrosive environments. With a narrow beamwidth and high front-to-back ratio, it is ideal for point-to-point and point-to-multipoint applications requiring durability and precision.
Features:
- The RFI YBS803-99 antenna is custom tuned for operation across the 540–1000 MHz frequency range, supporting a wide range of broadband applications.
- This antenna is constructed from all-welded 316 grade stainless steel, making it highly resistant to corrosion and suitable for extreme environmental conditions.
- The feed element is a full folded dipole, welded to the boom for maximum bandwidth, low intermodulation, and long-term reliability.
- The passive elements are through-mounted and welded on both sides of the boom for structural strength and consistent performance.
- The antenna includes a short 9302 Durathene cable tail with an N female connector, offering superior resistance to weathering and abrasion.
- The antenna supports stacking or baying using PH and PHE series phasing harnesses for higher gain configurations.
- The narrow beamwidth and high front-to-back ratio help reduce interference from other systems.
- The antenna rests at ground potential, providing excellent lightning protection and reduced precipitation static noise.
Application Areas:
- The antenna is ideal for point-to-point or point-to-multipoint communication in broadband RF systems.
- This antenna is suitable for trunking, cellular, and ISM band applications.
- It is designed for use in harsh or corrosive environments where rugged construction and reliability are essential.
