Double loops (and longer combinations) are a form of broadside gain antenna, created by using two loops in a single structure. There are many different forms. These antennas can be used in a vertical stack for horizontal polarization (as shown here) at upper HF when sufficient height is available, and for VHF.

The Double Inverted HF Delta Loop Vertical A Skeleton Slot Vertical with Low-Angle Radiation, Azimuth Gain and Horizontal Polarization for Lower Noise Here is an excellent example of what a slot antenna can do on the HF bands. This design for me is one of the biggest payoffs of a three-year adventure with slot antennas.

antennas mounted singularly (only one loop in the air). When mounting both antennas the SWR goes to 1:1 @ 3.8 MHz, just a little bit upper, due to the element's coupling. To phase the two loops, Dr. Ace WH2T suggested me to simply use quarter-wavelengths of 75-ohm coaxial cables feeds placed from any of the delta's feed-points simply to

Delta loops require a full wavelength of wire (1005/frequency = feet or , for instance 1005/146.52 = 6.859) or approximately 6′ 10 7/8″ gives me the length of the entire wire. Since I will be building a 3-sided delta loop, I divide that 6.859 / 3 = 2.29 feet or about 27 1/2″ per side.

It's a multi-band 80-6 meter wire dipole. ZS6BKW started with the G5RV and then conducted extensive computer modeling to increase the gain, flatten the SWR a bit, and smooth out the lobes. It's also about 10 feet shorter than an equivalent G5RV. The antenna must be fed with 39 feet of 450 ohm ladder line and also must have at least 70 feet of.
