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) > 0 dB
a
Free space average gain (Gv
+Gh) over FoV
> -3 (preferred) or -6 dBi
b
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.
a
Vertical linear polarization is sufficient.
b
Gv and Gh are measured and averaged over -45 to 90° in elevation, and ± 180° in azimuth.
