Do you want a multi-band HF antenna, but don't have an antenna transmatch (i.e. "tuner") to keep SWR low as you select your favorite band? Then, a multi-band HF "Fan Dipole Antenna" may be what you're looking for. The antenna consists of dipoles for each band connected to a single 50 ohm coaxial cable feedline.
In this video, Cory (N0ECK) and Alex (KD0YNH) take us step-by-step in designing, building, and using this simple, effective HF antenna. According to Alex and Cory, this antenna will work well on 80, 40, 20, and 15 meters without an antenna "tuner". Be sure there is separation between the dipoles to reduce signal cancellation.
