Frequently Asked Questions
Q: Is this GPS antenna compatible with all car navigation systems?
A: This universal active GPS antenna is designed to be compatible with the vast majority of car DVD players, GPS navigation units, and GPRS devices that use an SMA Male connector and operate on the standard GPS L1 frequency of 1575.42 MHz. Always check your device's connector type and frequency requirements before purchasing.
Q: How is the GPS antenna installed in the car?
A: Installation is simple and tool-free thanks to the magnetic mount base. Just place the antenna on any flat metal surface — such as the car roof, dashboard bracket, or bonnet — and route the 3-metre RG174 cable to your navigation device's SMA input port.
Q: What does "active" antenna mean and why does it matter?
A: An active GPS antenna contains a built-in Low Noise Amplifier (LNA) that boosts the incoming satellite signal before it travels along the cable to your device. This results in faster satellite acquisition, more accurate positioning, and a more stable connection — especially useful in vehicles where the antenna may be partially shielded by the car body.
