When in past i worked with SDR hardware i experimental that noise line in space is about -100dB, when i don’t amplify RF gain, when i amplify it, it is -80dB till -20dB. So other hand when i use different antenna pick value of noise is change, today i know that a antenna is a dipole network that can describe with scattering matrix.
