!!Example of the beverage construction * you can buy it there: [Top band beverages and wire antennas acessories|https://remoteqth.com/beverages-wire-antennas-acessories.php] The beverage is a long wire antenna installed very close to the ground. The antenna should be longer than 1 wavelength and installed at a height of less than 0,05 wavelength above ground. The beverage is usually terminated in a resistance at the end (opposite the feedpoint). Beverage antennas provide one of the least expensive and most reliable ways to improve DX capabilities on the low frequencies. With careful attention to design and construction, a single beverage antenna can be made to cover two directions with excellent performance over a very wide frequency range. The transformer at the end of the beverage is designed to match impedance of the antenna. A two-wire bi-directional beverage requires the antenna element to operate a balanced transmission line, as well as a conventional long wire antenna. The parallel wire line used to construct the antenna must be excited under near-perfect balanced transmission line conditions. This is why each of the parallel transmission line wires must be parallel to the ground. A line should not be constructed in a vertical fashion, using single support poles with one wire under the other. The closer the wire spacing of the line, the lower the impedance of the line, and the less critical installation-related unbalances become. The higher you install the line above ground, the less unbalance any unequal coupling to earth creates.
