Shure UA874US: Active Directional UHF Antenna with Log Periodic Dipole Array and Four-Position Gain Switch
The Shure UA874US is an active directional UHF antenna with an integrated amplifier for improved wireless signal reception. It uses a log periodic dipole array to produce a cardioid pattern toward the desired coverage area, achieving greater rejection of RF signals outside that area than standard 1/2 wave omnidirectional antennas. It suits stages, theaters, houses of worship and conference centers across Dubai, Abu Dhabi and the wider UAE.
Key Features
- Log periodic dipole array with a cardioid pattern toward the coverage area
- Integrated low-noise amplifier with a four-position gain selector switch
- Compensates for transmission loss in coaxial cable
- Works with all Shure wireless receivers and antenna distribution systems that provide 12 V DC bias
- Stand mounting via integrated threaded adapter, ceiling suspension, or wall mounting with the included swivel adapter bracket

The Shure UA874US is an active directional UHF antenna with an integrated amplifier. It uses a log periodic dipole array to create a cardioid pattern toward the desired coverage area.
Its directional cardioid pattern rejects RF signals from outside the coverage area better than a standard 1/2 wave omnidirectional antenna, which improves reception in busy RF environments.
The Shure UA874 has an integrated low-noise amplifier with a four-position gain selector switch that compensates for different amounts of coaxial cable signal loss.
The Shure UA874 works with all Shure wireless receivers and antenna distribution systems that provide 12 V DC bias.
The Shure UA874 can be stand-mounted using its integrated threaded adapter, suspended from a ceiling, or wall-mounted using the included swivel adapter bracket.
