If you want to squeeze a bit more gain out of your HF horizontal dipole antenna, you may find the Extended Double Zepp Antenna a useful alternative to the traditional 1/2 wavelength dipole.  Stan Gibilisco (W1GV) does an excellent job of explaining the theory, construction, and operation of this antenna.

The Extended Double Zepp Antenna is basically a collinear array of "two 5/8 waves in phase", giving a theoretical gain of 3 dB. Be sure to use balanced feed line such as 450 ohm ladder line, 300 ohm television twin lead, or homemade 600 feed line with a balanced "tuner" or a 4:1 current balun/"tuner" combination connected to your rig.
