Product Description

Product Description

Multi-Band COMBO Antenna GL-DY072 for GPS/GSM/FM-AM Integration

The GL-DY072 is a versatile multi-band COMBO antenna engineered for integrated GPS, GSM, and FM/AM applications. Featuring a dielectric GPS antenna with RHCP polarization and 2dBic gain (Zenith), it ensures precise navigation even in challenging environments. The GSM module operates across 824-960MHz/1710-1990MHz with 2dBi linear gain, while the FM/AM antenna covers 520-1629KHz/76-108MHz with 20/12dBi gain. All components share a 50Ω impedance and IP65-IP66 rated housing (excluding cable outlet) for durability. The LNA-enhanced GPS module includes 28±2dB gain and <1.5 noise figure for optimal signal clarity. Designed for -40°C to +85°C operation and 95% humidity resistance, this antenna supports automotive, industrial, and IoT deployments. Its compact form factor and screw-mount installation simplify integration into various platforms.
