At the feeding terminals I used two wires line with
450 Ohm wave impedance just because I had some stock of the home
made struts for the two wires line. At the antenna end the two
wires line was made by antenna design suitable for the place.
9:1 (450:50 Ohm) transformer used in the antenna feeding
terminals was a homebrew one that was similar to described in
the Reference 3.
7 shows picture of the transformer. Transformer was
installed under the two wires line in plastic food container.

Some tricky things about antenna termination load.
I used three termination loads in my experimenters with the Two
Wires Beverage Antenna. First one was a home brew 450 Ohm load
made from 45 each metal oxide film resistors in 4k7/2W that were
connected in double bridge. Figure 9
shows the termination load. The second one was a termination load
made from 10 each wire bound resistors in 4k7/5W soldered to bridge.
