四、Characteristics

1. Frequency Range: 118-137MHz.

2. Output Power: ≤1000 watts.

3. Gain: 2.15dBi.

4. Bandwidth: 19MHz.

5. Impedance: 50 ohms.

6. Voltage Standing Wave Ratio (VSWR): ≤ 1.5.

7. Polarization Mode: Vertical.

8. Connector: N-type Female.

9. Length: 0.9m.

10. Weight: 1.3Kg.

11. Material: Aluminum Alloy.

Note:The antenna is equipped with three aluminum struts, which are part of the VHF antenna. If three aluminum struts are not installed, the VSWR (or return loss) of the antenna is very high and the antenna does not work properly.

五、Case

The VHF antenna mounting bracket is 1.5m high (the height of the bracket is optional), and a steel pipe (60cm long and 6cm in diameter) is also required for auxiliary installation of the VHF antenna.
