I'm looking to build a 2m yagi, but I haven't got any money. Can I
make one out of aluminum coat hangers? I also have a 4-foot section of
1" PVC pipe laying around, and glue, tools etc.

Others presented good ideas. Ya know, an old TV antenna would make a
decent
yagi for 2m, and with people going to cable/satellite TV, you could
probably
find one for nothing or only a few dollars. Remove the elements you
don't
need, cut the remaining elements down to length, do a little rewiring as
needed, connect your feedline, and you're good to go. If you want
vertical
polarization, redrill the boom-to-mast mounting holes 90° from original.
I once did something similar with a 3 element 11m yagi... in about an
hour
or so including tuneup time, I turned it into a gamma-matched 6 element
2m
yagi. I used my VSWR-protected 2m rig's output indicator to indicate
proper
tuning by adjusting for maximum relative forward power.

When we got cable in the neighborhood my wife was threateing divorce over
all the TV antennas I would pick up off the curb during trash day.

Hmm... I envision stacked arrays! ;^)
