An external GPS antenna is a type of antenna that is mounted outside of a
device, such as a vehicle or a GPS receiver. It is commonly used in
applications that require a stronger and more reliable GPS signal, such as
in marine navigation or aircraft navigation. Unlike internal antennas that
are built directly into a device, external antennas are connected to the
device via a cable and require separate installation. External GPS antennas
come in a variety of shapes and sizes, including patch antennas and helix
antennas, and can be either passive or active. Active antennas contain an
amplifier that boosts the GPS signal, increasing its sensitivity and range.
In addition to improving GPS signal quality, an external GPS antenna can
also help to reduce interference from surrounding objects. Choosing the
right external GPS antenna for your application depends on a variety of
factors, including signal strength, range, and installation requirements.
