2.4 GHz PARABOLIC DISH ANTENNA 30-0050
Directional antennas are used in land mobile applications for a variety of purposes. As base station antennas,
they are used to provide a focus of signal strength in one direction while decreasing reception and
transmission in other directions (see diagram). In control applications they are used to aim as much energy in
one direction as possible to provide a reliable communications path.
Our parabolic dish antennas feature an all aluminum reflector and feed antenna. The antenna features a
rugged, adjustable mount. Azimuth and elevation angles are easily varied by threaded adjustments. The feed
system is completely sealed to keep out the weather and to prevent unwanted detuning. Antennas feature 10’
of RG142 cable with a reverse SMA connector for attachment to GINA.
