Australian ham Peter Parker (VK3YE) shows some of the capabilities of his homebrew "Half Square Antenna" for 10 MHz and above. A half square antenna is a wire antenna with two vertical radiators fed in phase. One vertical element (1/4 wave length) is fed at the top where it's attached to a SO-239 connector. The other side of the SO-239 is attached to a horizontal half wave phasing line, then connected to another vertical element (1/4 wave length) aiming at the ground.
Thanks to some help from a nearby Australian beach, Peter was able to make contact with EA8YT/M on 10 MHz, another station on 14 MHz, and finally an EA station on 7 MHz. As Peter suggests, you can set up your half square antenna with the help of two telescoping fiberglass fishing rods (squid poles)
