Lower cost antennas for higher volume applications or for more cost sensitive applications are available. L1 GPS receivers are manufactured by implementing a 20 dB LNA on board. For this reason, in many cost sensitive applications it may be necessary to select a passive antenna in conjunction with a low loss coaxial cable.
