I bought a used rooftop tv antenna at a garage sale so there are no
instructions. I know how to mount it and connect the coax, but I do
not recall which end points toward the tv station transmitter.

I know the UHF elements are the smaller ones and the VHF are the
larger ones. But which end goes toward the station? Here is a crude
drawing (below).

It's called a Yagi antenna, very common in ham radio. The narrow end points
toward the TV station's antenna; the wide end is the "back" of the antenna,
the reflector.
