Customer testimonials :
"I used to think that an external GPS antenna is not needed in most cases. I have re-thought that. Recently I experienced a total loss of GPS signals in a strange city without paper maps. I now have a Gilsson GPS antenna that I will not leave home without. " - Hank (read about his own Gilsson GPS antenna review)

Gilsson's amplified external GPS antennas are high performance GPS patch antennas with state-of-the-art low noise amplifiers, providing a better performing alternative to Garmin's popular low-profile GA 26C and GA 27C GPS antennas.

Optimized for GPS frequencies, our active antennas dramatically increase GPS signal reception and accuracy for your Garmin GPS receivers while consuming very little power. (Gilsson GPS antennas yield 28 dB signal gain vs only 16 dB gain from Garmin)

Best of all, Gilsson GPS antennas are available for only a fraction of the price of Garmin's GPS antennas! (MSRP is $99.99 for GA 26C and GA 27C models)

Our Garmin compatible GPS antennas feature versatile mounting options for handheld, automotive, aviation, and marine GPS applications.
