I can't figure out why RG-59 is looked to as the "small" cable of choice for
75 Ohm uses.  RG-6 is a far better cable.  I learned this last summer when I
had my DSS system installed.  The RG-59 cables in the house that worked fine
for CATV did NOT work as well for DSS.  I replaced everything in the house
with RG-6 and high quality "snap-on" F connectors (like the pros use) and
now have much better signal strengths to the dish.  RG-6 has a much better
shield and is just a better cable.

I best most guys using the AIDC converters use RG-59 as well.  Again, I'd
recommend RG-6 here also.
