Hi, folks (and maybe CW) - on his helpful hints pages, CW (kc7nod)
recommends the possible use of a balun (which I take to mean a
transformer?) at the coax-antenna junction of a loop antenna...

In this instance, can anyone advise what the ratio on this would be?
4:1? Another value? I'd like to try out this antenna design, and the
balun idea too.

My guess would be a 1:1 balun.

( I hope this is not a quiz) ;-)
