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
anyway.
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...
