Model Number 0310-814
GPS Antenna
The model 0310-814 GPS-AJ antenna is a rugged and lightweight annular patch design. Its radiation pattern has a deep null at the horizon that greatly reduces the susceptibility of the GPS system to interference from terrestrial signals. Field trials have successfully demonstrated this feature.

At a Glance:

• Frequency Range: 1575 MHz ± 10 MHz (L1)
• Polarization: RHCP
• VSWR: 1.7:1
• Axial Ratio @ Zenith: 2dB Maximum @ L1
