Description
The MHD-1575A (formerly MWSL-1203C) is a rugged L1 GPS Dielectric Loaded Antenna: SMA (male).
The rugged MHD-1575A antenna is balanced, isolating it from the device and enabling the antenna to reject common mode noise. The design and materials of the antenna constrain its near-field to a very small volume. Therefore materials near the antenna have negligible detuning effects and the antenna maintains its pattern and efficiency in the presence of dielectric loading.
The rugged MHD-1575A acts as its own filter, attenuating signals from common cellular and ISM frequencies by as much as 30dB. The MHD-1575A has a built in DC block to enable direct connection to receivers with DC on their input pin.
Key Features
- Negligible detuning in cluttered, dielectric loaded environments (hand-held, body-worn, close proximity to objects)
- Designed for harsh environments: exposed to force, dust and moisture
- Useable in scenarios where orientation of antenna is random
- Filters against interference from cellular and ISM bands
- Integrated O-ring water-seal
Applications
- UAV/AUV
- Asset Tracking
- Hand-Held Devices
- Vehicle GPS
- Emergency Locators
- Net Radio Location/Synchronization
- 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.
