1575.42 MHz GPS Antenna - 5 Volt

Frequency: The 1575.42 MHz frequency corresponds to the L1 band used by GPS satellites for civilian navigation. GPS antennas are specifically tuned to this frequency to receive signals from multiple GPS satellites in orbit.

Antenna Type: GPS antennas come in various forms, including patch antennas, helical antennas, and more. The choice of antenna type depends on the specific application and requirements.

Active vs. Passive: Some GPS antennas are active, meaning they require power (typically 3-5 volts) to amplify and process the received signals. Passive antennas do not require external power and are often used with high-sensitivity GPS receivers.

Voltage Supply: A 5V power supply is common for active GPS antennas. This voltage is provided to the antenna through a coaxial cable connected to a GPS receiver or module.

Coaxial Cable: GPS antennas are usually connected to a GPS receiver using a coaxial cable with an SMA or MCX connector. The cable carries both power and RF signals between the antenna and the receiver.

Mounting: GPS antennas are designed for various mounting options, such as magnetic mounts for vehicle use, adhesive mounts for fixed installations, or screw mounts for outdoor applications.

Gain: GPS antennas often have a gain value specified in decibels (dBi), which indicates their sensitivity and ability to receive GPS signals. Higher gain antennas can provide improved reception in challenging environments.

Compatibility: Ensure that the GPS antenna you choose is compatible with your GPS receiver or module in terms of frequency, voltage, and connector type.

Signal Quality: The performance of a GPS antenna can significantly affect the accuracy of GPS positioning. Antennas with good signal-to-noise ratios and low multipath interference are essential for precise location data.
