The multi feed point design ensures the right-handed circular polarization and phase center performance, and reduces the influence of measurement error; The antenna unit has high gain, good reception effect for low elevation satellite signals, and sufficient number of satellites available for the system; The low noise amplifier adopts pre filtering technology to effectively suppress out of band interference signals and improve the reliability of the system; The enclosure is protected by IP67, which provides a guarantee for the antenna to work in the field for a long time.<br><br>Material:plastic+metal colour: As shown<br><br>Package Contents: 1 x antenna(Does not include base) (Due to different product batches, the appearance may be different, which does not affect use.)<br><br>Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
