One of the simplest, least expensive antennas for the 6 meter amateur radio band can be found in your junk box.
In this video from Hayden Honeywood (VK7HH), we see how one piece of RG-58 coaxial cable can be used to make what the late Bill Orr (W6SAI) called the "Cobra Antenna."
Hayden's modification of Orr's "classic" antenna is easy-to-make and can be used for both "field" use and at your home station.
The completed antenna can be added to your emergency "go kit" for rapid deployment for SOTA/POTA operations.
