An antenna for mobile communication on the 80-meter amateur radio band

The antenna element is two meters long and 12 millimeters in diameter. At its top is an 80 µH inductor. The top capacitance consists of two flat profiles, each 1 meter long and 10 mm wide screwed onto a ceramic insulator.  A good counterpoise should be ensured. The resonance can be adjusted with a clamp on the coil. Naturally, the antenna is narrowband...

 

... and works surprisingly well.
