NGA-LA24-N-DCx GPS L1 In line Amplifier with 24dB Gain NAELCOM’s GPS Low Noise in-line Amplifier NGA-LA24-N series with L1 band pass filter provides high gain (24dB typical) in cases where GPS and antennas are separated by large distances. Long cables runs require the use of low loss cable, heavy and costly cables. NGA-LA24-N will allow increasing from 60 meters to more than 200 meters between the GPS antenna and a timing receiver. Two amplifiers may be chained to reach a distance up to 365 meters (CNT400 cable). NGA-LA24-N is available in two versions, one DC PASS powered by GPS receiver through antenna coaxial cable which accepts power from 3VDC to 16VDC, the other in DC Block which Block the DC from the GPS receiver and amplify the signal from the GPS passive antenna (Railways applications). Due to his exceptional dimensions (84mm L x 18mm D) the NGA-LA24-N is cylindrical and can be installed inside most of antenna pipe mount and integrated with cables in-line. NGA-LA24-N series is rugged and weatherproof (IP67), corrosion resistant (INOX housing), it can be used also with surge arrestor (NGA-NMNBF-Family).
