Special Note

1. Difference between radio antenna and network antenna:

This link antenna is a small radio antenna and is used in the base station mode of the radio station erected by itself; both the built-in radio and the external radio mode are installed on the nose, and the large radio in the external radio mode uses another transmitting large antenna.

2. Antenna interface distinction: There are mainly two types of interfaces, one is TNC-J, the other is SMA-J. Please pay attention to the interface of your instrument when purchasing.

3. Select the antenna model according to the brand: the frequency of the radio antenna of different brands may be different, and the inappropriate frequency may affect the signal.
