 A good quality preamplifier is essential due to losses during signal propagation via antenna and due to low intensities of reflected signal. A good quality preamplifier is essential due to losses during signal propagation via antenna and due to low intensities of reflected signal.

Its benefit is mainly in amplification of signal from antenna (thus decreasing the influence of antenna’s lead (?? svod antény) ​and a noise from receiver). Furthermore it reduces complications connected to signal radiation from receiver’s oscillator.+[[http://​www.mlab.cz/​Modules/​CommRF/​LNA01A/​LNA01A_Bottom_Small.JPG|LNA01A]] is a preamplifier designed for meteor detection in 2m band.
