I have a random wire antenna, which is a is a clothes line about 25
feet off the ground and about 45 feet long. This arrives at the deck
on my third floor flat, where I have a balun. I run the antenna to
the balun and a ground line from the balun to a copper rod in the
ground, and a coax feed line from the balun to the receiver.
This seems to work quite well as my signal strength improves somewhat,
but more importantly, my noise level drops dramatically when compared
to the whip on my small receiver.
I am confused about the "best" ground method. Should I place the
balun near the ground rod and run the coax feed line up into my flat?
Will this improve anything or, is the set up I have fine?

You could improve the RF ground to the balun by making the ground wire
much shorter. Run a single wire from the near end of the antenna down to
the ground where the balun would be located. The balun would be grounded
with a short wire to a near by ground rod. Then run the coax feed line
from the balun to the house.
