Description
MHC-1575C (formerly MWSL1251SF) Mini-Helical L1 GPS Antenna: PCB Fed.
This miniature dielectric-loaded antenna uses MARUWA’s distinctive materials technology to provide circularly-polarized gain from a small volume, where the housing environment causes a higher degree of frequency down-tuning.
This product is designed for solder or spring connection to the host PCB and can be supplied with a plastic sleeve to provide mechanical protection and also to stabilize frequency in the presence of a wide variety of housing features and materials.
Key Features
- Designed for installation with 5mm gap from antenna side to host PCB ground-plane
- Filters against interference from cellular and ISM bands
- Balanced design rejects common mode noise from ground plane
- Solder-pad installation to device PCB
Applications
- Asset Tracking
- Hand Held Devices
- UAV/AUV
- Traffic Enforcement
- Emergency Locators
- Wildlife Tracking
- Seismic Monitors/Measuring
- Marine Tracking

Features of Sarantel Antennas
Helical Conformation is applied to MARUWA’s Dielectric Ceramic and our antenna has 4 features as follows.
- Wide Beam-width
- Jamming-Resistant
- Insusceptible to human body
- Compact Size
Wide Beam-width
Due to its wide beam-width, Sarantel Antennas can be attached at any angle.
Jamming Resistant
When receiving radio waves in the gap between buildings or trees, antenna receive signals from satellites and signals reflected by interference. In case of GPS, it calculates the location by using distance from the satellite. The actual signals from satellite and reflected signals are different in the route and if antenna recognizes both are correct signals, the result may become inaccurate.
As Sarantel Antennas are designed to receive the signals from satellite more strongly and less strongly to the reflected signals, they are jamming-resistant and calculate the location very precisely.
High Interference Resistance
Sarantel Antenna demonstrates high interference resistance. The chart on right hand side shows feature of “Return Loss”;
- Case 1: Free space only for antennas without the mobile device
- Case 2: Antenna placed in the mobile device and holding it by hand
- Case 3: Antenna placed in the mobile device and holding it by hand and close to human body
As Sarantel Antenna does not get interfered by human body, it shows high performance and feature.
Compact Size
The compact size is realized by using its high Q dielectric Ceramic.
