Description

The GPS Indoor Antenna 28 dBi 3 MTR is a high-performance active GPS antenna designed to provide accurate and reliable satellite signal reception in indoor and semi-enclosed environments. Featuring a built-in Low Noise Amplifier (LNA) with 25–28 dBi gain, it enhances weak GPS signals for stable positioning and navigation. The antenna operates at the GPS L1 frequency (1575.42 MHz) and is supplied with a 3-meter RG-174 cable, allowing flexible installation near windows or optimal reception points. It is an ideal solution for GPS receivers, vehicle tracking systems, telematics, IoT devices, navigation equipment, and timing applications.
