Here's another simple, easily made dipole antenna that covers the 40 and 20 meter Amateur Radio bands.  Separate dipoles for each band are joined at a center connector and fed with the same 50-ohm coaxial feed line.  According to KC2IRV, this antenna will also work on 80 meters with a sturdy antenna "tuner." Fifteen meter operation is also possible using the 3rd harmonic of 7 MHz.  SWR will be slightly higher on 15 meters than 40 meters, but can be controlled with an antenna "tuner."  KC2IRV uses 1-inch/2.54 cm PVC plumbing Tees for insulators.  A cheap, multiband HF antenna that works.
