External power amplifier unit is designed to amplify the radio frequency signal, filter and combine several frequencies into one radio frequency output to ensure simultaneous operation of several transmitters and receivers at different frequency bands. It is used to increase the range of the portable system when used in the vehicle.
EPA-400 filters the transmitting signal, resulting in improved transmission quality. Additionally, the EPA-400 includes filtering and low-noise amplification (LNA) of the receive path, which boosts the received signal strength while minimizing interference. The device also has built-in power amplifier diagnostics to help identify and resolve any potential issues with the transmission process. Finally, the EPA-400 allows for the switching of external antennas, providing greater flexibility in signal routing
The unit is normally placed in rugged 4U or 6U Gator case, or can be installed inside existing vehicle 19-inches rack
