The GPS  Low-noise Amplifier, is an in-line amplifier that is required whenever long antenna cable lengths reduce or weaken the GPS signal below the receiver's recommended minimum input level. The maximum cable length permitted without an in-line amplifier depends on the types of cable and receiver used.
