The GPS signal is very weak at the Earth's surface. Imagine what happens when you have an interferring cell-phone tower in your neighborhood!
This module inserts a passive band-pass minimum loss filter followed by an ultra-low-noise amplifier followed by an additional band-pass filter, in order to eliminate most unwanted energy. Additional notch filters are added tuned at tower frequencies. The net gain is 10 dB.
Combine it with our GNSS band-pass filter unit - check the last picture!
