The antenna was installed and tested by UA4QA. Despite of the antenna was installed at a small height between the roofs of a two houses, on the 20- meters the antenna did + 2... + 4 balls (at S-Scale) compare to usual one- wire Windom designed for the band. Figure 1 shows the design of the antenna.

Antenna made of seven lengths in 0.477- lambda and 3-mm diameter each. The wires were going through two ebonite rings and soldered in the places of the insulators and the connection of the one- wire feeder. (Note by I.G.: There is no information about placement the rings on the antenna).

  Feeder should be athwart to the Antenna for the distance at least 2/3 lambda and then should not have sharp bending.
