GPS Active Antenna 28dB MCX Male RG174 Magnetic Mount

Boost your GPS signal with the GPS Active Antenna 28dB Gain MCX Male RG174 Magnetic Base. Designed for 1575.42 MHz GPS frequency, this active antenna delivers a powerful 28dB gain to ensure fast, accurate satellite acquisition — perfect for dash cams, GPS locators, navigation units, and other in-vehicle GPS devices.

The strong magnetic base mounts securely to your vehicle's roof or any ferrous metal surface, keeping the antenna firmly in place even at highway speeds. The flexible RG174 low-loss coaxial cable routes easily through door seals or windows, while the MCX male connector plugs directly into compatible GPS receivers and modules.

Frequently Asked Questions

Q: What devices is the GPS Active Antenna MCX Male RG174 compatible with?

A: This GPS active antenna with MCX male connector is compatible with any GPS receiver, module, or dash cam that features an MCX antenna port and operates on the standard 1575.42 MHz GPS L1 frequency. It is widely used with portable navigation units, dash cameras with GPS, fleet trackers, and GPS development modules.

Q: How does the 28dB gain improve GPS signal reception?

A: The built-in 28dB low-noise amplifier strengthens incoming GPS satellite signals before they travel through the coaxial cable to your device. This significantly improves satellite acquisition speed and accuracy, especially in areas with limited sky visibility such as urban canyons, garages, or under heavy foliage.

Q: How does the magnetic mount base work?

A: The magnetic base uses a powerful permanent magnet to attach instantly and firmly to any ferrous (iron or steel) metal surface — such as a vehicle roof, hood, or trunk lid — with no tools or adhesives required. Simply place it on a clean metal surface and it holds securely, even at high speeds.

Q: What is the difference between an active and passive GPS antenna?

A: An active GPS antenna, like this 28dB model, contains a built-in amplifier that boosts the GPS signal directly at the antenna before it travels down the cable. This compensates for cable signal loss and improves overall reception. A passive antenna has no amplifier and is typically used only for very short cable runs where signal loss is minimal.
