PRODUCT NOTES / 02
Additional Information
The Shure UA874 is an active directional antenna covering 470-698MHz, using a log-periodic dipole array to deliver a cardioid pickup pattern that rejects RF interference from outside its target coverage area, improving reception for UHF and VHF wireless microphone systems in congested RF environments.
Its integrated amplifier offers four gain settings to compensate for coaxial cable run length and signal loss, and it draws 12V DC bias power directly from a compatible Shure receiver or antenna distribution system, simplifying installation without a separate power supply.
