A few words from our customers: 

Featured testimonial:
"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 his Gilsson GPS antenna review)

"I have a Garmin 2620 and the internal antenna just doesn't cut it when using the unit in a car. I lost the satellite signal constantly. I began shopping for an antenna and found that Garmin's is $99 bucks (gulp!). The antenna is perfect. It has a nice magnetic mount, it is very small and I have not lost reception yet. The signal is strong and constant and makes using my 2620 so much better." - taucancri (from
