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?

GW,

So you have a Horizontal {Flat} Random Wire Antenna with a
Balun and long Vertical Ground Wire run. Which is a 'basic'
"Low Noise SWL Antenna" using the 'design concepts' that were
popularized by John Doty.

So - You have strong "S9" Signal Levels and Low Noise:
Then I would say - This Antenna Is Working A-OK For You ! )
[ Hey - If It Ain't Broken Don't Try Fixing It ! ]

Having say (written) the above. "IF" you have 3'-5' or more 'space'
between where the Ground Wire runs up to your Balun along the side
of the building/deck. You may wish to modify the the Current layout
of the Horizontal {Flat} Random Wire Antenna to an Inverted "L" Antenna.

1. Move (Relocate) the Balun to the Ground Rod and mount the Balun
on or within inches of the Ground Rod.

2. Replace (Extend) the Coax Cable so that it runs from your
Radio/Receivers to the location of the Ground Rod and Balun.

3. Replace (Extend) the Wire Antenna Element from the Horizontal
End Point down to the location of the Ground Rod and Balun.

4. Connect the Ground Wire, Coax Cable and Antenna Wire Element
to the Balun.

5. Run/Route a 'separate' Heavy Ground Wire from the Ground Rod
to the Radio/Receivers.
