Frequently Asked Questions About Best Car GPS Antenna
What is the difference between an active and a passive GPS antenna?
An active GPS antenna (like all models reviewed here) includes a Low Noise Amplifier (LNA), typically providing around 28dB of gain. This amplifier boosts the weak satellite signal before it travels down the cable to your receiver. A passive antenna simply funnels the raw signal. Active antennas provide far superior signal acquisition speed and stability, especially in areas with obstructions (like cities or thick forests).
Where is the best place to mount my car GPS antenna for optimal signal strength?
The ideal location is always one with the clearest view of the sky, but practically, this is often inside the vehicle. The best internal placements are usually high on the dashboard near the front glass, or mounted to the rear deck beneath the back window. Since most of the best car gps antenna models include magnetic bases, mounting them on a metal plate under the dashboard is a popular method to ensure a good ground plane and secure fit without external visibility.
Why do some GPS antennas use an SMA connector while others use Fakra?
The SMA connector is a common, threaded connector widely used in RF equipment, including most aftermarket car head units and dedicated GPS tracking modules. Fakra connectors were developed specifically for the automotive industry (especially in Europe) to be more durable and color-coded, simplifying wiring harness installation in factory settings. If replacing a factory unit, you likely need a Fakra antenna.
Does cable length affect the GPS signal strength?
Yes, cable length can degrade the GPS signal, especially with passive antennas. However, the high LNA gain (28dB) built into these active antennas is specifically designed to overcome the signal loss associated with standard cable lengths (like the common 3m/10ft found in the reviewed models). This ensures the signal arriving at your navigation unit remains strong.
Can I use a GPS antenna designed for tracking on my car stereo head unit?
Absolutely. Most high-quality best car gps antenna products, such as the AEDIKO or SZSAUTO units, are rated for wide applications. Since the base GPS frequency (1575.42MHz) is standardized, an antenna designed for a tracker or DVR will work perfectly fine with a compatible head unit, provided the connector (usually SMA) is correct.
What does the LNA Gain (28dB) mean in practical terms?
LNA Gain refers to how much the antenna amplifies the weak signal received from the satellites. A gain of 28dB is considered powerful for vehicle use. In practical terms, it means the antenna is highly sensitive and can maintain a stable satellite lock much more effectively than low-gain or passive antennas, reducing the chances of dropped navigation in challenging environments like parking garages or downtown areas with tall buildings.
