The coax only has a loss of 1 db for the length I am running it. I doubt
that at 2 meters I would see any benift of putting the preamp at the
antenna. It is as easy to get a 1 db or less noise figure at 2 meters as
it is to make any preamp and the 221 does need some help on the receiving
side.
From the articals I have read the beam width of most any single antennas
at 2 meters is wide enough the ground noise will override that ammount of
loss.


Agreed. Your 1 dB preamp just became a 2 dB preamp and the visible ground
temperature likely overrode either figure and by a good margin. I suspect
the original poster with his S9 sun noise and "seeing" the Galactic plane
was being a bit optimistic.
