GNSS Standalone Antenna Requirements
Frequency Range
• Narrow-band GPS: 1572.42 MHz ± 2 MHz minimum
• Wide-band GPS and GLONASS: 1565 to 1606 MHz recommend-
ed
Field of View (FoV)
• Omni-directional in azimuth
• -45° to 90° in elevation
Polarization (average Gv/Gh)
Free space average gain (Gv
+Gh) over FoV
Gain
• Maximum gain and uniform coverage in the high elevation an-
gle and zenith
• Gain in azimuth plane is not desired
Average 3D gain
> -5 dBi
Isolation between GNSS and
LTE Main (Primary)
> 10 dB in all uplink bands
Typical VSWR
< 2:5:1
Polarization
Any other than LHCP (Left-Hand Circular Polarized) is acceptable.
Vertical linear polarization is sufficient.
Gv and Gh are measured and averaged over -45 to 90° in elevation, and ± 180° in azimuth.
