Is anyone aware of a small directional antenna that is useful for direction
finding at VHF? My understanding is that Doppler antennas work only while
moving (true?) and what I need is a directional antenna that can be used
while at rest. Low efficiency and relatively broad main lobe are OK as long
as physical size is small.

Have a look at the HB9CV designs. The physical size is quite small and
mechanical construction is not difficult. I have a commercial one for
70cm at it works well and is small and easy to work with.

Here a link to a fellow ham who publishes instructions and drawings:
