I used Al strip, bent in a circle, for the loop (used from 0.1 to 30 MHz). It
was cheap and easy but making a multi-turn loop would have been quite a task.

I remember years ago someone suggested the following to make a 'simple'
multi-turn loop:

Get a length of 'flat computer cable' -- e.g., like the IDE cables for
PC HD's. Such cable can be found in 'surplus' outlets -- sometimes as
an 'end piece' on a cable reel.

Form your loop -- cutting the flat cable to the length you desire.
Connect every-other cable wire to every-other-other (HI!HI!) cable wire.
Your ends, then, are the two outside wires on either side of the
cross-over connection zone.

Such cable can be re-'sized' to just the loop count you want by
un-zipping unwanted runs of the cable.

Depending on how neatly you mount your loop, you should have no problems
with wires shifting position with relation to one another and de-tuning
the resultant lash-up.
