An inline amplifier may be required when the antenna cable length attenuates the GPS signal to a level below the receiver’s recommended minimum input level.
The Starlink inline amplifiers from Forsberg Services are premium quality devices. They are rugged and watertight, finished in gold-plated brass, and optimized for GNSS/GPS applications.
All other RF frequencies are filtered and rejected to remove any unwanted signals that may otherwise enter the coaxial cable and cause electromagnetic interference (EMI).
APPLICATIONS and USES
Connectors can be same both ends or different; TNC, SMA, N-Type, BNC options.
No power supply needed; DC power is derived from the GPS repeater/receiving device via the coaxial cable.
Use of an inline amplifier can significantly extend the distance between the outdoor antenna and the GPS receiver.
There are two main variables to consider:
The combination of these two factors determine the GPS signal strength entering the receiver.
Consult the repeater/receiver manual to ascertain the permissible input signal level range.
The amplifiers are designed to be installed in-line with the antenna feeder cable.
The ideal place for an amplifier is at, or very near, the antenna location.
This is where the signal is strongest and is not affected by RF noise.
It can be attached directly to the antenna connector, as shown in the photograph.
Or it can be placed indoors where it is easily accessed from inside the building, using a short length of good quality coaxial cable to connect it to the antenna.
FalTech GPS can advise on attenuation factors of a range of different cable types in order to calculate which amplifier is best for your situation.
