QRH400 Datasheet
Quad Ridged Horn Antenna
QRH400 is a brother of DRH370. This dual-polarized broadband antenna with frequency from 400
MHz up to 6 GHz, this antenna is perfect for big chambers and EMC measurements. The addition oftwo spirit levels is a matter of course, thanks to which your measurement in both planes will be very
accurate and fun.
