If you would like to play around with building an antenna, 2 meters is a band that it is very easy to build antennas for.
Here is a 2 meter, 2 el quad.
Thia is a very cheap antenna, can be built from almost nothing, and will show you just how easy it is.
It is not a antenna you would want to leave up, however it will allow you to see how the idea works, and you can build it in one afternoon. homepage.ntlworld.com/s.amesbury/M3FVB/2elementquad.htm
Simple, just some wire and a few Pcs of hardware.
You can build off of this basic idea, and learn as you go
Here is a 4 El built the same way www.geocities.com/siliconvalley/2775/quadpic.html
Here are plans for a 4 el Quad, it is built to stand up to being mounted outside.
This is the same as the first 2 meter beam I built.
I ripped the boom from a 2x6 on the table saw, drilled the holes with a hand drill, and built this antenna on a Sunday. Start to on the air. members.shaw.ca/ve7gds/2mtrqd.htm
Make sure that you seal the wood with some good exterior Paint, and it will suprise you how well it will hold up!
Here is a cool deal for building your own Quads, just punch in the frequency you want, and it will crunch the numbers for you! www.dxzone.com/cgi-bin/dir/jump2.cgi?ID=3267
