Hi,
Did all this when studying electronics years ago.
A full wave at 40Mhz = 7.5M. If you divide this by 4 you'll have a quarter wave antenna that'd be perfect, but that's far too big at 1.8m.
Just use any piece of wire as long as you possibly can without it looking silly. It will be absolutely fine.
