Feature:1. You can use this ADS‑B antenna to effectively improve the signal attenuation of the cable, very practical.2. The ADS‑B antenna module can also improve the signal‑to‑noise ratio and largely increase sensitivity.3. The antenna can be fixed on a grounded conductive object, which can reduce electrostatic coupling interference.4. And there is no need to connect thunder protection device when the antenna is fixed on ground.5. With a compact size and a light weight, the durable antenna is very easy to install, carry and store.Specification:Item Type: ADS-B AntennaGain: 2.0dBiFrequency Range: 1060-1120 (MHz).Package List:1 x ADS-B AntennaNote:The antenna can be fixed on a grounded conductive object, which can reduce electrostatic coupling interference. No need to connect thunder protection device. In case of an accident, it is recommended that the operation be performed by professionals. Only applicable to ADS‑B 1090MHZ antenna, the picture does not include other accessory demonstration.
