Jirous JRA-25DD MIMO Precision Parabolic Antenna


The JRA-25 Deep Dish MIMO Precision dual-polarized parabolic antenna is designed for directional links with MIMO mode in the 2.4 GHz frequency band.
The antenna is designed for environments with multiple reflections over long distances. Its deep dish design increases isolation between antennas on the mast and increases the front-to-back ratio.
The Precision version includes the massive JDMW-900 mount designed for microwave links.

FEATURES:

  • Dual-polarization antenna, horizontal/vertical polarization or 2x45°
  • Precision, durable mount designed for professional microwave links
  • Deep antenna increases isolation between antennas on the mast
  • Easy to use with GentleCLIP
  • Long distances in challenging environments
  • Parabolic shield (plastic) included

Electrical parameters:

  • Frequency range: 2.3 – 2.7 GHz
  • Gain: 25 ± 1 dBi
  • Cable loss: 0.75 dB
  • Frequency factor SWR: 2.4 – 2.5 GHz ≤ 1.4 (other frequency bands ≤ 1.6)
  • Beamwidth -3 dB: 10˚
  • Front/Back Ratio: ≥ 41 dB
  • Polarization: Linear, vertical/horizontal or 2x45°
  • Polarization Fine Adjustment: ± 5°

Mechanical Parameters:

  • Parabola: Ø 900 mm, aluminum alloy
  • Dome: UV-resistant ABS plastic
  • Connector Type: R-SMA on Cable
  • Mast Mounting: Ø 40 - 120 mm
  • Operating wind load: 140 km/h (87 mph)
  • Wind load resistance: 210 km/h (130 mph)
  • Antenna weight: 8.2 kg
  • Bracket weight: 3.2 kg
  • Shipping dimensions: 1000 x 990 x 430 mm / 18 kg

The antenna can be used in conjunction with the GentleCLIP bracket, making it easy to mount devices with a clip system. The antenna bracket has separate snap-in nuts for easy installation and azimuth and elevation adjustment. The antenna is supplied with a bracket that allows for easy mounting on a mast.
The bracket can be mounted separately on the mast. Then, you can simply hang the antenna on the mast. The mount allows for precise adjustment in both directions.
In areas where strong winds are expected, mounting on a pole with a minimum diameter of ø 50 mm is recommended.

The radiator has been internally treated with a high-frequency "hydrophobic coating" for increased moisture resistance.
