        QRH18

        Quad Ridged Horn Antenna

        The addition of two-spirit levels is a matter of course, thanks to which your measurement in both planes will be very accurate and fun.

        Cloned antenna series are available through AU Technology, which guarantees constant parameters.

        Manufactured with RF SPIN’s SPM Technology to achieve the best mechanical and radio parameters.
