Here's an easy, inexpensive, and versatile antenna from Denis (VE3BF).  The classic delta loop antenna can be used for both home and field use.  The antenna exhibits modest gain and can be vertically polarized by feeding the antenna at the bottom.  To get multiband performance (20 meters through 10 meters), use 450 ohm ladder line, 300 ohm TV twin lead, or homemade 600 ohm twin lead in conjunction with a 4:1 balun and an antenna transmatch (i.e. "tuner").  I've built several variations of this design for 80-10 meter coverage.  Best of all, most of the materials can be found in  your "junk box" or at the nearest building supply or home improvement outlet. Have fun!
