Shure UA874 Active Directional Antenna Overview
The payoff
RF Antenna decisions, organized around the whole rig.
The UA874 is the standard Shure paddleA directional antenna (paddle, LPDA, helical) aimed at the stage — focuses coverage where the performers are and rejects RF from elsewhere. for remote-mounting receive antennas: a directional log-periodic array with a built-in amplifier whose four-position gainHow much the preamp amplifies the incoming signal. Too low and you’re hunting through hiss; too high and peaks clip. switch exists to make up long coax runs, not to "boost range". Its 70-degree beamwidth aims the pickup at the stage and rejects the audience-side RFRadio Frequency — the wireless part of wireless. RF planning is why big rigs scan, coordinate, and combine antennas instead of hoping. junk, and the RF overload LED tells you when +12 dB was the wrong answer.
