Antenna, Omni Directional Wideband

EM-6851 | 2 GHz – 18 GHz

The EM-6851 Omni-Directional Wideband Antenna is capable of operating as either a transmitting or receiving antenna over the 2 to 18 GHz frequency range. This antenna provides a 45% size reduction when compared to similarly performing models. The antenna is enclosed in a weather resistant radome. The length of the support rod allows a microwave amplifier to be connected directly to the output connector, reducing the potential signal loss compared to an amplifier connected at a more distant point.
