If the budget it tight the th2mk3 is a great triband antenna. During the day 40
is not quite a option. You could rig a sloper or dipole down the road

I agree with others that a 40' crank up would be a good choice. Such as
Tashjian LM237 or LM354 if the budget allows. Not a mast.
Regarding antennas, I think for teaching 20m only might be a difficult
and frustrating experience, since the band is often crowded. I think a
small tri will give the most flexibility. Something like an A4S which
should leave some tower capacity for a 12/17m dipole. Then some short
masts on the buildings for am 80/40m dipole.
OTOH, some dipoles on the roof are a good way to get started, cheaply.
