MEA-1227-MM

Antennas RF Overview

The MEA-1227-MM is a dual-band GNSS antenna designed for GPS, GLONASS, and other global navigation satellite systems. It operates within the L1 and L2 frequency bands, specifically covering 1.227 GHz to 1.602 GHz. The unit features an SMA male connector and utilizes a magnetic mounting style for secure attachment. Key electrical specifications include a gain of 28 dB, a VSWR of 1.5:1 to 1.7:1, and bandwidths of 1175 MHz to 1260 MHz and 1561 MHz to 1606 MHz. The radome-style design has a height of 21.5 mm.

Antennas RF Feature Summary

• Dual-band support for L1 and L2 GNSS frequencies
• Magnetic mounting configuration for rapid installation
• IP67 and IP69 ingress protection ratings
• Integrated 3-meter cable with filter components

Antennas RF Applications

• Vehicle tracking and telematics systems
• Maritime navigation equipment
• Mobile surveying instruments
• Automotive infotainment and navigation modules

Antennas RF Procurement Notes

Verify the specific datasheet version for the MEA-1227-MM to confirm the exact cable length and filter specifications, as distributor listings may vary in detail. Ensure the SMA male connector matches the receiving equipment interface. Confirm that the magnetic mount provides sufficient holding force for the intended application environment. Check for RoHS compliance documentation if required by project standards.

Antennas RF Selection Notes

Select this model when a compact, magnetically mounted dual-band GNSS solution is required for mobile platforms. The integrated cable simplifies wiring compared to connector-only antennas. Consider the IP67/IP69 rating for outdoor or harsh environmental durability. Compare against fixed-mount alternatives if vibration resistance is critical beyond magnetic hold strength.

Antennas RF Part Context

Maxtena Inc produces specialized RF antennas for navigation and communication systems. The MEA-1227-MM belongs to their GNSS antenna portfolio, focusing on multi-constellation support. This component complements other Maxtena products like the MEA-1227-SM screw-mount variant, offering flexibility in installation methods while maintaining similar dual-band performance characteristics for L1/L2 applications.

Antennas RF Replacement Considerations

The MEA-1227-SM serves as a mechanical alternative with screw mounting instead of magnetic. Both share dual-band L1/L2 capabilities. Verify connector type compatibility, as both use SMA male interfaces. Ensure replacement units meet the same IP67/IP69 protection requirements if environmental sealing is necessary.
