If you ever wanted a bidirectional, monoband, broadside HF antenna, then the Bobtail Curtain Antenna may be for you. The antenna derives from experimental work done by Ernest Sterba in the early 20th century.
Stan Gibilisco (W1GV) does a good job of explaining the theory behind this antenna and how to build one for your use. I've used Sterba-inspired antennas during ARRL Field Day and found them to deliver excellent DX contacts.
Curtain arrays are still used by international shortwave stations to deliver powerful signals to targeted areas around the world. Build a simple Bobtail Curtain Antenna and see what results you get.
