Default Need Ideas for HF Antenna at Fire Station

Our local fire station would like us to provide an HF station to be
operated by hams during an emergencies. They have offered to pay the
cost of this. We already have an VHF station there. The problem is the
antenna. It cannot be visible (or at least not be at all obvious; they
are allowing the VHF antenna on the roof now.). The most likely needed
band is 75/80 meters, for in-state communications. So we need high-angle
radiation, and a vertical does not seem to be a good choice.

The roof is metal, so putting an antenna in the attic will not work.
The building is a fairly large 2 or 3 story structure, and in the
country with no other buildings nearby.

How about a 1/4 wave radiator, sloping down from the roof, with the shield
of the coax connected to the metal roof. It would take some trimming. If you
use black insulated wire, it will be almost invisible.
