Gilsson vs. Garmin
external GPS antenna comparison

Many potential customers want to know just how well Gilsson external GPS antennas compare with Garmin original antennas.

We are often asked how our antennas perform and what it means to have 28 dB signal gain as compared to 16 dB gain from Garmin's antenna.

To answer this question we conducted a field test comparing the our MCX external GPS antenna with Garmin's GA 27C (part #010-10052-05). We used Garmin's popular iQue 3600 PDA to test the external antennas.

Here are the results of our tests*:
