Shure UA840 UHF Antenna Distribution System
The Shure UA840 is a powerful UHF Antenna Distribution System that supercharges your wireless microphone setup! Expand your system effortlessly by splitting one pair of antennas to multiple receivers. It amplifies RF signals to keep those signals strong, even when splitting power to multiple output ports. Each unit lets up to four receivers share the same antennas, and the CASCADE port opens the door to connecting a fifth receiver or another UA840.
Features:
- Expandability Galore - Ideal for large UHF wireless systems. Connect up to four wireless receivers to the same two antennas per unit, and link multiple UA840s for up to 20 receivers in total!
- Wide Compatibility - Works seamlessly with all wireless microphone receivers within a compatible frequency range.
- Smart CASCADE Ports - Two 50 BNC-type antenna CASCADE ports enable adding another UA840 or a fifth wireless receiver, making large systems a breeze.
- Power Daisy-Chaining - Up to five receivers can be easily connected to a single power source via the Power OUTPUT ports.
- Clean Signals - Delivers low noise and minimal intermodulation distortion for crystal-clear audio.
- Signal Compensation - Amplifies signals to counteract strength loss when splitting, ensuring strong signals reach receivers.
- Front-Mount Option - Comes with hardware for front-mounting antennas, if you prefer.
