GPS Antenna, GPS USB Antenna & Acessories

Most GPS receivers have an antenna built in to them. The two most popular types of antennas used in GPS receivers are "patch" and "quadrifilar helix" or "quad helix" for short. This are normally used when stronger satellite signals are needed.
The reasons to need an external GPS antenna:
* For use in a vehicle where the GPS receiver cannot or will not be placed near a window.
* For use in urban canyons (tall buildings).
* For use any place that the receiver doesn't have a good view of the sky.
* To minimize temporary loss of signal when in a vehicle in motion.
