Marine GPS antenna

WHY USE AN EXTERNAL GPS ANTENNA?

An external GPS antenna can be useful in the following situations:

To improve GPS signal reception: If you're using a navigation unit in an environment with poor GPS signal reception, such as a building or dense forest area, or if your boat's GPS sonar is in the enclosed cockpit, an external GPS antenna can help improve signal reception. This is because the external antenna is generally more sensitive and accurate than the antennas built into navigation devices, which can be useful for improving location and direction accuracy. It should be mounted high and outside.

To increase GPS signal range: If you are using a navigation device in a boat, the external GPS antenna can help increase the signal range. This is because the external antenna is usually stronger than the antennas built into the navigation devices, which can be useful for receiving the signal in difficult conditions or at great distances.

To replace a defective antenna: If the GPS antenna built into your navigation device is defective or damaged, you can use an external GPS antenna to replace it. This can be useful for continuing to use your navigation device without having to replace the entire device.

WHERE TO FIX AN EXTERNAL GPS ANTENNA ?

The external marine GPS antenna is usually mounted on the outside of the boat, preferably on the roof or stern, to receive an optimum signal. It is connected to the navigation device via a cable and is powered by a battery or by the device to which it is connected.

External marine GPS antennas are designed to withstand the weather and harsh conditions found at sea, such as waves, rain and corrosion. They are generally more sensitive and accurate than GPS antennas built into navigation devices, which can be useful for improving location and direction accuracy.
