ADA-MK-76 is the most compact GPS antenna available on
the current market. Its state-of-the-art technology allows for
miniature without compromising performance. With good
coverage almost all the way to the horizon, it performs
excellently in foliage or urban canyon environment -- even in
the presence of electromagnetic interference!
Featuring diminutive and rugged enclosure and unparalleled
performance, ADA-MK-76 is compatible with almost every
GPS receiver model on the markets and provides an excellent
alternative for a vast range of GPS applications including
AVL, Vehicle Navigation, Aviation, and Military.
