تست عملکرد GPS-3M
Description:
A GPS antenna is a device
used for receiving and expanding radio signals sent by distinct
frequencies coming from GPS satellites. These antennas will convert them
into electronic signals so they can be used by GPS receivers. Once the
GPS receiver obtains the output from the GPS antenna, it can calculate
the position accurately.
Active antennas come with powerful
amplifiers that permit them to pick signals from longer distances. In
fact, the signals received by these amplified antennas are much stronger
than the GPS device.
This high quality GPS antenna is suitable for
a whole range of applications such as in your car, drone or motorbike.
This GPS antenna comes with a huge 5M long cable and is perfect to mount
at a suitable spot on your vehicle. This GPS antenna features a high
quality gold plated SMA male connector.
GPS antenna housing is fully
waterproof so you can easily use it in the open air (e.g. fix it on the
car roof). Built-in magnet allows you to install antenna without
additional holders.
