Shure UA874 Active Directional Antenna
Key Features
  • Directs a Cardioid Pattern Toward Target

The Shure UA874 Active Directional Antenna uses a log periodic dipole array to offer enhanced reception when directed toward the desired coverage area. An integrated amplifier and four gain settings compensate for varying degrees of coaxial cable signal loss. The UA874 can be mounted on a microphone stand, suspended from the ceiling or mounted to a wall using the integrated swivel adapter bracket.

Are these made for permanent outdoor use?

Are these made for permanent outdoor use?
Asked by: Jerald
They can be mounted permanently or used in a mobile kit. They are large paddles and improve the pickup of the wireless frequency being broadcast by the mics. We have a set at our church permanently and I have a set in a Shure wireless 4 pack I rent for productions work.

If I am placing my receiving units relatively near the transmitters and using a snake box to the mixer is there a need for this antenna? It was included in my quote - possibly unnecessarily. Thanks.

No, in the situation as you describe the antenna is not necessary.

how many microphones can connect too this ?
Asked by: Anonymous
This antenna can receive signal from any number of active transmitters within range (based on the antenna's position and gain settings) that are transmitting between 470698 MHz. To clarify, this item's purpose in your wireless setup is to act as an extension of your receivers which, when properly placed and configured according to your application, can improve your transmitter(s) signal reception. However, it should be noted that your receivers are the devices that are actually connecting (or syncing) with your transmitters to interpret the captured signal of each active wireless microphone or bodypack. Thus, any limitations in number of transmitters you are able to use simultaneously would be based on the capabilities and coordination of your receivers rather than the number or type of antennas you are using.

do I need one or tow of these?
Asked by: Anonymous
This would depend on whether your specific application calls for a diversity or non-diversity wireless system and what kind of coverage is needed. In many circumstances however, using two is most common.
