The EM-6865 Omni-Directional Wideband Antenna is capable of operating as either a transmitting or receiving antenna over the 2 to 18 GHz frequency range.

The EM-6865 consists of two-brass conical elements connected point-topoint to form a hourglass shaped antenna element. The center conductor of a rigid coaxial cable is connected to the upper cone, while the shield is connected to the lower cone. The cable connects to a Type “N” (female) connector fastened to a phenolic base plate.

A 25.4 cm (10”) support rod provides a means for mounting the antenna to any tripod with a 1/4-20 mount.

The length of the support rod allows a microwave amplifier to be connected directly to the output connector of the antenna, reducing the potential signal loss compared to an amplifier connected at another point in the signal path.
