    The loss in that feed line is 3.2 dB at 1 GHz; approximately 5 dB at the GPS frequency (1.575 42 GHz). This feed line loss can be avoided by placing an LNA at the antenna, which supplies enough gain to offset the loss. An LNA is a key component at the front-end of a radio receiver circuit to help reduce unwanted noise in particular.
