There is no difference if the balun is on the input or output side of an

In theory, no.
In practice, there can be a big difference.

That's only true of an ideal balun. A real current balun has a finite
common mode impedance, which is typically designed to be about 10 times
the nominal operating impedance.

David,
Most any indoor antenna is in close proximity to the transceiver, and it
is quite likely (even with the most carefully balanced antennas) to have
RF floating around most everywhere, including the transceiver chassis
and any earthing wires.
I would suggest that you may be better off
I'll second Don's suggestion about using a 1/4 wave 'counterpoise' and
forgetting the balun!
Philosophically, I keep all passive components that I can do without out of
the antenna system simply because are no passive components! If something
doesn't add gain or power, it absorbs signal or
