Compact VHF fox hunting antenna
 

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.

Thanks,

Build Moxen Rectangle. Search Google for "moxen calculator".

George,
You can find a Moxon at this site, as well as a ton of other great
antenna info.

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:
