Jirous Parabolic antenna JRA-28DD MIMO Precision

Jirous JRA-28DD MIMO Precision Parabolic Antenna

The JRA-28 Deep Dish MIMO Precision dual-polarization 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 very long or medium distances in challenging conditions.
Its deep dish design increases isolation between antennas on the mast and increases the front-to-rear signal ratio.

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
• Extremely long distances in challenging environments
• Parabolic shield (plastic) included

• Frequency range: 2.3 – 2.7 GHz
• Gain: 27.6 ± 1 dBi
• Cable loss: 0.75 dB
• Frequency SWR: 2.4 – 2.5 GHz ≤ 1.4 (other frequency bands ≤ 1.7)
• Beamwidth -3 dB: 7˚
• Front-to-back ratio: ≥ 44 dB
• Polarization: Linear, vertical/horizontal or 2x45°
• Polarization accuracy: ± 5°

Mechanical parameters:

• Parabola: Ø 1200 mm, aluminum alloy
• Dome: UV-resistant ABS plastic
• Connector type: R-SMA on cable
• Mast mounting: Ø 80 - 120 mm
  - Ø 60 - 80 mm with adjustable wind brace kit
• Wind load:
