YNHAC25四臂螺旋双频高精度定位天线

The YNHAC25 is a four-arm spiral dual-band antenna. JS-HAC25 can receive signals in the L1(1559MHz-1615MHz) and L2(1200MHz-1246MHz) frequency band.The four-arm spiral antenna is mounted on a cylindrical ceramic substrate by four metal lines bent according to specific rules, without any grounding.It has the characteristics of Zapper antenna and vertical antenna.This clever structure enables the antenna to have good gain in any direction and good directional pattern characteristics.The four-arm helical antenna has a comprehensive 360-degree reception capacity. When integrated into the navigator, the four-arm helical antenna can receive regardless of the positioning position of the navigator, which is different from the limitation that the micro-strip patch GPS antenna needs to be laid flat to receive well.
