WebAn LNA is useful to help lower the noise figure of a radio system which results in higher SNR values (especially at the UHF and higher bands), and can be used to overcome losses in the signal chain from components like coax cables and connectors. WebFor example, averaging 4 measurements, one can improve signal-to-noise ratio twice, averaging 100 measurement will reduce the noise level 10 times, and so on. One limiting factor in improving quality of the measurements by averaging is the time needed to repeat the measurements.
