Ralph calls his design a "Folded Inverted-Vee Antenna." Ralph says this antenna gets more bandwidth than a dipole or vertical antenna.
Ralph takes you through the design, construction, and testing phases of this basic antenna which covers 3.5 MHz through 4.0 MHz.

Here are some comments from Ralph:
In this video I will be showing you how I created a Folded Inverted-Vee Antenna for the 3.5 to 4.0 MHz Amateur Radio 80 meter band. I will walk you through the whole process so you can create your own for any frequency you choose. Why do this? A Folded Dipole or Folded Inverted-Vee antenna has significantly wider bandwidth than its non-folded cousins. I wanted to increase the bandwidth of my antenna to cover more of the 80m band.
