Jirous JRMD-680-10/11

Parabolic antenna JRMD-680-10/11. Antenna JRMD 680–10/11 is designed for microwave links at the frequency band 10 and 11 GHz. The new generation is coming in a deep reflector dish design with a massive holder. The antenna is supplied with a holder that allows easy mounting on a mast. The holder can be installed separately on the mast. Subsequently, you can simply hang up the antenna with microwave unit into it. The holder allows precise adjustment in both directions. Ready for right and left side mounting. In the areas with the expected occurrence of the strong winds mounting on the mast with minimal ø 50 mm is recommended.

Key features:

• deep parabola for better parameters
• easy to assembly: first the holder and then the antenna only by 2 screws
• fine setting elevation (of gradient) and azimuth ± 20°
• extreme wind stability

Design for MW units:

• Mimosa
• Racom
• Alcoma
• Summit
• UBNT AF-11 - necessary to use JXAF-11 adapter
• Other adaptors on request
