Mini GPS Antenna

Model: MK-1

Lowest Power Conumption of Its Kind on Market

Overview

MK-1 is the most diminutive GPS antenna featuring lowest power consumption currently available on the market. Its state-of-the-art technology allows for the small size with no loss in performance. With good coverage almost all the way to the horizon, it performs excellently in foliage or urban canyon environment as well as in the presence of electromagnetic interference.

Featuring diminutive/rugged enclosure and unparalleled performance, MK-1 is compatible with almost every GPS receiver model on the market and provides an excellent alternative for a vast range of GPS applications including AVL, Vehicle Navigation, Aviation, and Military.
