I repeat my advice from yesterday -- WHICH RG6?

RG-designations used to be rigid specifications for cable. That has not 
been true for at least 40 years. All the RG-numbers tell us is the 
impedance and the approximate size. RG6 cables are somewhere between 
RG59 and RG11. If you believe it tells you more than that, you're out of 
touch with reality.
