Building a Base CB Antenna ?
 

Well at 27 MHz one is still plagued with atmospheric noise such as
lightning and manmade noise. In most instances it will overcome teh
galactic noise from beyond the atmosphere. At 2 M and above galactic
noise is more prominent but at considerable lower levels than the sky
noise at 11M. Around 20G or so comics rays become a noise source.

Also FM has advnatages in reception in that most noies has amplitude
components that are averaged out in FM detection. The major noise that
FM has to overcome is the thermal noise generated within the receiver.
