2-element quad antennas are very popular due to their compact size and gain similar to a more element Yagi. In addition, they can be designed to obtain an input impedance of 50 Ohm.

This design can operate at 27.5 MHz. I have added a script that allows us to plot the gain and front-to-back ratio as a function of element spacing. See this video:
We can see that both cannot be maximized at the same time, but it is preferable to choose the maximum F/B since the gain changes relatively little.

To create the Scilab script, I started from a basic design in AN-SOF and then exported it as a *.sce file.
