The UA874 series of antennas delivers improved wireless signal reception for VHF and UHF wireless systems
แผงรับสัญญาณคลื่นไมโครโฟนไร้สาย จากยี่ห้อ Shure ใช้การเชื่อมต่อด้วย BNC Connector มาพร้อมกับ Low-noise signal amplifier และมีสวิทช์สำหรับปรับและเลือก Gain ได้ 4 ตำแหน่ง
The UA874 series of antennas delivers improved wireless signal reception for VHF and UHF wireless systems. Features include rejection of RF signals outside the coverage area and an integrated amplifier with four gain settings.
UA874 uses a log periodic dipole array to produce a cardioid pattern towards the desired coverage area with greater rejection of RF signals outside the coverage area when compared to standard ½ wave omnidirectional antennas. An integrated amplifier with four gain settings compensate for varying degrees of coaxial cable signal loss.
The UA874 can be stand-mounted, suspended from the ceiling, or wall-mounted using the included swivel adapter bracket.
Features :
- Low-noise signal amplifier compensates for insertion loss in coaxial cable
- Compatible with Shure wireless receivers and antenna distribution systems that provide 10–15 V DC bias
- Integrated threaded adapter mounts easily to microphone stands
- Four-position gain selector switch
