What would happen if he didn't use a balun?

It sounds like that is serving as a dipole.
I too would strongly suspect that is a 75 ohm BALANCED output.
You should be able to remove the wires which are serving as the "dipole" and
run them to a 1:1 balun and the other side of the balun to a 50-75 ohm
unbalanced antenna. Or, to the input of a FM power amp....

If the output is really Unbalanced, and he fed an unbalanced ant of 50
ohms--nothing--as likely a 1.5:1 (75/50) match as not...

Or, depending on the type of ant he picks (75 ohm bal/unbal), and taking for
granted the output of the rig is balanced--probably just a distortion of the
radiation field of the ant (won't EXACTLY perform as modeled)...

Even if he feeds a bal ant of 200 ohms (folded dipole, and output is
balanced, all he sees is a high (200/75) SWR, and distance is reduced...

But, hey, I am a newbie... that is only my best guess(s)...

Warmest regards,
John
