Sounds about right to me Andrew.  Assuming you're talking about the low 
HF bands, atmospheric noise would be the limiting factor way before 
system noise would be an issue.

Hence, one wouldn't notice any difference in s/n when comparing Head Amplifiers of similar gain with a 1 or 4 dB noise figure? Or have I got something wrong!!!!!
