We could probably all suggest one antenna design or another.  There are many
possibilities.  Jerry, K5OE, has a home brewers page which has a few
peoples' antenna ideas.  I have constructed my own design beam which is a
combination of some of Jerry's ideas and the tried and true DL6WU Yagi
design, well known to many VHF DXers.

My design can be found at http://www.qsl.net/vk3jed/2m70cmant1html.html.  I
have worked UO-14 and SO-35 on it, and have tested it on FO-20, with beacon
strength signals into FO-20, using 2W uplink power.  I have worked ZL on
UO-14 while literally walking down the street!  (lucky it was late at night,
or someone might have wondered what was going on :) ).
