I have used RG6 (and other 'scrap' coax) for some of my ground radials (with 
the center conductor and shield 
connected together at the base plate).  I have trained my electrons to travel 
on the outer edges of the radials which 
makes for the need for less radials to get the antenna to start working when 
using large diameter wire (like coax!).

I believe that the more radials, is always better, but I have observed that the 
antennas start 'playing' with only 2-3 
larger diameter radials as opposed to using radials composed of number 24 (or 
smaller diameter).

My present coaxial inverted Ls ( 2 on 160M, 2 on 75M, 4 on 40M, 4 on 20M) have 
a total of about 6 miles of radials.  
My first 75M coaxial inverted L at this QTH was put up with only 3 radials 
(scrap RG8, and RG6) and my first QSO 
was a VK6 about an hour before sunset.

My goal is for about 60 radials on each antenna and I am using everything from 
Number 8 to Number 18 along with 
old RG58, RG8X, and some RG6 that I was able to get before the price rise of 
copper.

Years ago I did use a 42 inch wide copper window screening as a double radial 
for a 20M vertical.  Antenna worked 
very well!
