  If you want a simple, inexpensive, and efficient antenna, please consider this tri-band HF (40/20/10 meters) design from Stephen Flanigan (K4SRF). You may already have most of the antenna materials in your "junk box." Although Stephen says he made this "Fan Dipole" to cover only 40, 20, and 10 meters, you could use the 40-meter element as a 3/2 wavelength antenna on the 15 meter band.
