    X-Band, Omnidirectional Antenna, Description

    This antenna was originally designed to be used by RACONs, or RAdar beaCONs: a device normally used to mark the location of a Lighthouse or a Marine Buoy, as an aid to maritime navigation. RACONs operate within the X-band range of 9.32-9.50 GHz. Traditionally, a RACON signal identified itself on a radar screen as a dash line, followed by a Morse Code signature. The SL-9402-386 was developed as the antenna component of a RACON system.

    Following its initial release, we revised the design to cover the entire X-band spectrum, from approximately 8 GHz to 12 GHz. Naturally Omnidirectional, Broadband antennas are vertically polarized. However, this model is Horizontally polarized, making the SL-9402-386 a particular and peculiar antenna.

    In free space, the antenna exhibits a nominal gain of approximately +3 dBil. When mounted directly on a large ground plane, gains as large as +8 dBil can be realized at low elevation angles and at the antenna's horizon.
