If you want up to 3dB gain broadside to your current HF Dipole Antenna, consider building an Extended Double Zepp Antenna. According to Stan Gibilisco (W1GV), the EDZ Antenna is a "collinear array of two 5/8 waves in phase." In this video, Stan reviews the theory behind this classic antenna, how to build the antenna, and what kind of feed line is required to make the EDZ work properly. You will also need a balanced "tuner" or a "tuner"/balun combination to get maximum efficiency from this design. Also, you will need more room for the antenna elements, especially if you make this antenna to cover Amateur Radio bands from 80 to 10 meters. You may find the gain worth the effort in making this unique HF antenna.
