In the worst case scenario this means that through several gain stages the noise floor rises at a greater rate than the desired signal level which and can eventually envelop the desired signal and prevent reception of the signal altogether. In short noise floor is generally the background noise you detect in a recording file. Replaced 30 feet of rg 8x feed line to the shack with 30 ft of rg 213 coax.
