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.
- Directs a Cardioid Pattern Toward Target
- Four-Position Gain Selector Switch
- Low-Noise Signal Amplifier
- Makes Up for Coaxial Transmission Loss

Shure UA874US Reviews
Much safer to have those puddles on my gigs.
Bought for a large sanctuary system experiencing signal drop
I bought this antenna in hopes that it would solve a signal drop out problem in a church sanctuary. Installed just before Christmas services and we have not had a drop off in four months of use. Problem solved, and install was super easy- mounted it on a boom mic stand. Thanks B&H and Shure!
Makes a huge difference in signal strength!
I had purchased 4 new Shure wireless units and racked them up in a church balcony system. First service with them and I had multiple drop outs and needed to solve the problem quickly. I ordered two of these from B&H and the arrived in time to get them installed before the next week's service. I have had 3 months of use and have had ZERO drop outs. I should have gone this route from the beginning. The antennas alone were just not enough to keep a solid signal connection. Super satisfied with the ease of install and the sleek look of these, but the real deal is the stellar performance.
Just what I needed
Needed remote antennas for an important event.� Bought two of these.� Worked well.
Signal drop outs in the church sanctuary are gone!
We purchased two of these to help remedy signal drop out from our new SHURE wireless systems. We had installed the mics in the same rack that the old ones came out of, but we had very low and even loss of total signal during our first two uses. After purchasing and installing these, we have had nothing but full signal and we could not be happier. These worked like magic!
Great remote antenna
This antenna has solved our Shure BLX audio drop out issues. It is a bit pricey but has solved our random drop out issues which have plagued us for a while.
