Actually, if you want cheap and effective look at the PA0RDT mini-whip
active antenna:
    http://dl1dbc.net/SAQ/Mwhip/Article_pa0rdt-Mini-Whip_English.pdf

The active antenna is relatively small and easy to build with no
particularly expensive or difficult to find parts.  Some builders
have even used MPF-102 and 2N3866 or 2N3904 transistors instead of
the U310 and 2N5109.
