The antenna is designed for outdoor usage IP68  and features a TNC female connector. It can be mounted directly on a pole (add pole mount needed). The antenna is developed to avoid overlapping frames in regions with high air traffic and to have a deeper focused look into special sectors. Especially useful for redundancy operating systems or as back up. The mounting receptacle is a 5/8″ thread.

ATTENTION active antenna, additional Bias Tee is needed

or your SDR is able to activate the internal Bias Tee

Rod antennas are sensitive to polarization and can completely lose reception. This antenna is insensitive to polarization effects without loss of range. Because of the extreme sharp narrow band this antenna is best in areas where a lot of transmitters with different frequencies are used. No additional filters are necessary.

Because of the antenna pattern this antenna has no doughnut effect. There is no need to adjust the gain of the SDR, there is no need for additional filter because this antenna is extremly narrowband.
