Why do I need to use a NMEA amplifier?

If you connect several devices that need to know your position at the NMEA output of your GPS there is the risk that one of the devices connected to this output disturbs others. For example, a turned off device overloads the NMEA bus much more than when it is powered. This is particularly the case of VHF DSC. An NMEA output is not intended to power more than 2 devices. In the event of disturbances due to overloading the NMEA bus, the devices connected to it will no longer receive the positioning data regularly, which will cause positioning delays or no positioning at all.

If you use a NMEA controlled autopilot, it is very important that the data transmitted to it is perfectly reliable and regular.

The only solution to this problem is to install a NMEA amplifier:

The NMEA AMN010-2 amplifier has a sensitive input that does not overload the NMEA output of the GPS. This input is isolated by opto-coupler which in addition to solving the problems of ground loops and floating ground levels protects the GPS from any possible return of disturbance coming from a device or wiring of the installation. It has 4 powerful and independent outputs that will provide your devices with reliable positioning data.

The NMEA amplifier AMN010-2:

The AMN010-2 is a high efficiency NMEA amplifier. It corrects and amplifies the NMEA signal and send it on 4 independent NMEA outputs.

The AMN010-2 amplifier is a high performance NMEA amplifier. Its powerful, independent outputs can be used with any device that has an isolated NMEA input or not, regardless of its input impedance. Its amplification ratio is greater than 1000. It has an auxiliary input / output for coupling as many AMN010-2 amplifiers as necessary to obtain the desired number of NMEA outputs without mobilizing a power outputs.
