Description
Antenna technical parameters:
1. Connect two microphone host antennas to a single antenna box
2. A daily antenna can also be connected to the box. The boxes can be connected in series to achieve regional signal coverage. The function can be selected according to the actual situation of the project.
3. The microphone host or antenna amplifier host has its own power supply, eliminating the need for separate power to the box. If the microphone host lacks a built-in power supply, it can be connected directly to a 5-18V power adapter.
4. Directionality: 720° omnidirectional
5. Working frequency: 490MHz-960MHz
6. Roundness: ≤5dB;
7. Active gain: 14±3dB
8. Noise coefficient: ≤3.5dB
9. Output P-1dB: ≥-10dBm
10. Operating voltage: DC 5-18V
11. Working current: ≤35mA
12. VSWR：≤3
