Shure UA8 1/2 Wave Omnidirectional Receiver Antenna (578-638 MHz)

The Shure UA8-578-638 is a half-wave omnidirectional receiver antenna that helps Shure wireless systems maintain a clean, stable signal within the 578 to 638 MHz UHF band. It connects through a standard BNC jack, so you can attach it directly to a compatible receiver or a PSM transmitter without adapters or extra hardware.

This antenna works with many Shure product lines, including UHF-R, ULX, SLX, ULX-D, BLX4R, and the PSM 900 and PSM 1000 in-ear monitoring systems, provided the devices share the same frequency range. Whether you handle corporate events, concert touring, house-of-worship services, or broadcast productions, using the UA8-578-638 can reduce dropouts and improve overall RF consistency.

Installation is straightforward. The antenna’s elbow swivel allows positioning at 0, 45, or 90 degrees, letting you aim the radiating element toward the stage, podium, or audience area that needs coverage. This flexibility is especially valuable when receivers sit in a rack, on a mixing desk, or in a portable rig where space and sightlines vary from venue to venue.

Because the UA8-578-638 is omnidirectional, it captures signals arriving from any direction around the antenna, which helps when performers or presenters move across the stage or when multiple transmitters are located in different spots. Pairing it with quality coax cable and proper antenna distribution further optimizes multi-channel wireless setups.
