The AT1 directional antenna provides a high gain signal in a specific direction when you use the wireless system over a very long distance, upgrading receiving and transmitting capabilities. With the built-in 12 dB booster and another 6 dBi gain from the high directional antenna structure, the efficiency of receiving and transmitting over long distances is greatly increased. The AT1 can be installed on any microphone stand using the included 5/8" threaded adapter. The design of the overal structure makes the AT1 suitable for outdoor environment applications.
