How about a small Yagi made with "rubber duckies"?

I admit it, I don't know what you mean. :)

USMCBrat-

I think the cubical quad may be the best antenna for your situation, but
there are other options.

"Rubber duckie" refers to the shortened rubber-coated antenna on a
walkie talkie. If several of these were arranged as a yagi, they would
not have the sharp points your full size yagi has.

Another is called a "Doppler Direction Finder", and requires an
electronics package. It has 4 vertical antennas arranged in a square on
a metal plate. Take a look at

for an example of this kind of system. The vertical antennas might be
"rubber duckies" as well.

I would also have a search for 'Handifinder', it is a simplified version of
the above that uses 2 small loop antennas and is easily hand portable. It is
cheap and easy to build and I think kits are available. It does have a 180
degree ambiguity but in real use that is not a great problem.
