QRH300 Datasheet
Quad Ridged Horn Antenna
QRH300 is dual-polarized broadband antenna with a frequency from 300 MHz. This antenna isperfect for big chambers and EMC measurements. The addition of two spirit levels is a matter ofcourse, thanks to which your measurement in both planes will be very accurate and fun.
