You can probably use a "mouse" and a shop vacuum to get the first 
lightweight pull string down the conduit.  Use the lightweight string to 
pull a stronger pull rope.  I've never pulled 500 feet but with 
virtually a straight run I doubt you'll have any trouble.  I'm not sure 
if pulling grease is compatible with RG6 and you probably won't need it 

I used 1 1/2" conduit to run 4 10 gauge conductors with two sharp 90's 
and one gradual 90 bend over 100 feet with no trouble.  Also, 3 12 gauge 
solid conductors 125 feet through a 3/4" conduit with two 90's.  Didn't 
use any pulling grease...
