If you want your HF dipole to have better gain and some directivity, try this "classic" Extended Double Zepp Antenna. The EDZ antenna described by Stan Gibilisco (W1GV) is a "collinear array of two 5/8 waves in phase", which delivers approximately 3 dB gain broadside to the antenna.  According to Stan, construction of this antenna is simple and uses locally available materials. Just follow the diagram provided, and you should have a dipole with a bit more"punch" for your ham station. For more antenna ideas from Stan, please visit his website at: http://sciencewriter.net.

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=3j3BsYbzwvw If you're thinking about a new antenna for the ARRL Field Day (last full weekend of June), why not consider the "Extended Double Zepp" for your portable station?  The EDZ is a collinear array of two 5/8 waves in phase that can deliver up to 3dB of gain for your favorite amateur radio band.  Because EDZ's can be a bit large (1.25 wavelengths measured horizontally), you may want to consider something like 20, 15,or 10 meters for this fairly simple project. In this video, Stan Gibilisco (W1GV) explains the theory and operating parameters of this antenna which can deliver better performance than the basic dipole antenna. According to AC5UP, the EDZ antenna "is easy to build, isn't fussy about height or proximity to other wires, can be tuned to a broadband 1:1 match, and makes a dandy general purpose SWL antenna that

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.

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.
