Rrad goes by the square of height for 'short' verticals so you would
see roughly a 40% increase by going to 60'. The difference in your
signal would also depend on your ground loss and this would be smaller
for a poor ground.
While I'm here, is there a source of #16 or #18 CCS wire in large
quanties? I saw a large spool of welding wire that appeared
to be copper coated, but it seems the copper coating is to thin
to make this wire useful for radials.
