Features:
- Frequency Band: 470~960 MHz
- Effective Working Angle: 100 degree
- Antenna Gain: 10dB
- Net Weight: 400g
- Power Supply: 12V, 50mA
- Booster Gain: 3dB/10dB Selectable
การติดตั้ง แผงรับสัญญาณ-ขยายสัญญาณไมโครโฟนไร้สาย JTS UDA 49A
- Select the booster gain according to the antenna cable length (type RG213) [UDA-49A only]: 3dB: 15 meters max.; 10dB: 50 meters max.
- Connect one end of antenna cable to the antenna. Then, mount the antenna onto a mic. stand or suspend it from the ceiling.
- Connect the other end of cable to the wireless receiver or antenna distribution system.
- The LED will light up, when the power is supplied. [UDA-49A only]
- Walk around and find out the optimum location for UDA-49A/UDA-49P..
*For better performance, it is recommended to use two antennas with diversity wireless systems.
