One more DIY Groundplane Field Antenna version

Bret at the SurvivalComms Youtube channel (it is not me, just a name coincidence I did not expect) has built his own version of the Jungle Antenna (Link 1, Link 2)

He uses a ring made from ABS rods to “hang” and position the ground wires, and the handheld’s radio own antenna. From the looks of it performance can further be increased with a telescopic antenna like the Diamond RH-770.

He also has a build of a discone antenna with the same method.
