Circular External Damp Proof GPS Car Antenna

The effect of GPS receiving antenna is  to transform the electromagnetic wave energy conversion radio signal from the satellite receiver into energy which can be toojkthe electronic device can supply intake applications. Our GPS antenna is composed of ceramic body and active antenna amplifier. The plastic shell package, has the characteristics of waterproof. Also the product has the advantages of small volume. There is a 3M sticker at the bottom of antenna, convenient installation and use.
