TetraAnt 868 08 70

Elboxrf 8dBi Directional Panel Antenna

Antenna designed for radiomodems and active RFID systems operating in the 858-878 MHz (ERC REC 70-30) bandwidth
The useful bandwidth is 20 MHz where VSWR 1.8:1
A high performance medium gain antenna - a 8 dBi at over 70 degrees half power beamwidth
Can be mounted for a horizontal or vertical polarization. Here, for a horizontal polarization - an E vector plane is parallel to the ground plane
Antenna built with high quality materials, like aluminium alloy, stineless steel bolts and nuts and a zinc galvanized U-bolt
A heavy-duty construction for the all-weather operation
Product is covered by a 5-year warranty
