The antenna was born after numerous experiments that were made in past three years. Russian Patent # 125777 was obtained for the antenna. Prototype of the antenna is described in Reference 1, 2. Some experimenters on the born of the antenna are described in Reference 3. Figure 1 shows the Directional Antenna. Figure 1 shows all antenna dimension and placement of the antenna parts.

The antenna has some parts that are similar to the prototype. Loop part of the antenna made of a coaxial cable and this one is placed vertically. There are two phase- shift capacitors- C1 and C2. However horizontal wires have some modifications. Two long wires are connected to one part of the loop. One of the long wires (that is placed in the direction of the maxima radiation) form the main lobe. Other one long wire suppresses back radiation. Two short wires provide symmetrical of the antenna.
