Standard Installation using NovAtel Equipment

Using NovAtel’s GNSS antennas and coaxial cables, the GNSS receiver’s requirement for +15 dB to +40 dB gain from the antenna, including the antenna element, LNA and cable, at its RF input is easily met. All NovAtel GNSS antennas employ a built-in, low-noise amplifier (LNA), which typically provides +25 to +35 dB of gain to the GNSS satellite signal. The power to the antenna LNA is provided through the center conductor of the receiver’s RF port.

Figure: Standard NovAtel RF Equipment Configuration shows a standard antenna cable configuration using NovAtel’s 5 metre, ~3 dB loss RF cable and a GNSS antenna with a +29 dB gain LNA.

The minimum recommended cascaded antenna gain is +15 dB (+20 dB with HDR enabled).
For optimum GNSS tracking and TerraStar L-Band reception, +25 dB to +35 dB is recommended.
