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