Is there a directional antenna that can be used with a handheld
scanner ? I'm trying to track down the origin of a signal in my
neighborhood.

Can one be made easily ?

If the 'signal' radio is at a fixed location, a loop antenna on your
handheld will give you alot of information about where the 'signal' is. A
loop antenna is usually an easy antenna to fabricate.
Direction finding with loops was used extensively during WWII. The
'signal' will be somewhere along a line corresponding with the null of
signal strength. You will need to move the location of your hand held to
two or more locations, as you have already figured out.
The null will be along a line perpendicular to the plane of the loop. The
'signal' will be maximum when the loop is pointed with its edges toward the
'signal'.
