Parabolic antenna JRC-24 DuplEX

Diagram

dual-polarized antenna, horizontal and vertical polarization
the highest isolation! 53 dB
only 1 antenna instead 2 save money for mast!
extra high front to back ratio
metallic collar assures increased isolation between antenna on mast = lower interference between links
directional links for medium distance, also short in difficult conditions
setting elevation (of gradient) and azimuth has independent adjustment
VSWR and isolation are measured during the manufacture of every piece
outdoor usage
you can count attainable distance from section of calculation
radom (plastic parabola cover) for each antenna free!

Frequency range	5,45 - 5,9 GHz

VSWR	≤ 1,5
Isolation between connectors	53dB (≥50dB)
Front to back ratio	≥ 38 dB
Beamwidth_{-3 dB}	9°
Connector	N - Female - JRC-24DuplEX R-SMA - JRC-24DuplEX-SMA
Polarization	linear, horizontal and vertical
Parabola	ø 38 cm aluminium alloy with baking colour
Cover	UV steady plastic ABS
Instalation for mast	ø 27 - 74 mm

The radiator is internally treated by high frequency technology "Hydrophobic coating" which increases resistance against humidity.

Using with GentleBOX JR-300 we recommend JRC-24DuplEX-SMA with R-SMA connectors. Using "N" you need 1 pcs of Adaptor N right angle at horizontal connector.
