The antenna was designed for installation in a field conditions or limited space. Antenna may be installed at a low- height mast. Antenna does not required guys and takes small room for installation.  Figure 1 shows schematic of the antenna.

 

At first experimenters the two horizontal wires were bended (prototype Antenna UA6AGW V.40. 20, ANTENTOP 01, 2014, p.: 42). Then to reduce the occupied room the loop of the antenna was curved. Picture 1 shows the Loop.

 

 

Two traverses for horizontal wires made from plastic fishing poles in 4- meter length of each. The horizontal wires made from audio cord in 1-mm diameter (18- AWG). Picture 2 shows the traverse. Classical antenna insulators do not use in the antenna design. Fishing cord and plastic ties are used instead of those ones. The hook made from thick bare wire is installed at some ends of the fishing cord. Capacitor C1 is a high- voltage capacitor. Variable capacitor C2 is usual tuning capacitor 12- 495- pF from an old tube receiver.
