Recommended to protect it against water and snow.
Antenna impedance - assembled version: 75, 150, 450, 600 Ohms.Bi-directional (Reversible) beverage antenna.Broadband 0.2 MHz to 30 MHz (optimal 0.2 to 14 MHz).It means that you cannot leave second port open or short! Also if you use first port on 160m and second on 80m than second port have to have load impedance on 160m and first port on 80m. NOTE: TWO coax output beverage antenna works right only, when both ports are loaded with right impedance on the same band. The higher you install the line above ground, the less unbalance any unequal coupling to earth creates. The closer the wire spacing of the line, the lower the impedance of the line, and the less critical installation-related unbalances become. A line should not be constructed in a vertical fashion, using single support poles with one wire under the other. This is why each of the parallel transmission line wires must be parallel to the ground. The parallel wire line used to construct the antenna must be excited under near-perfect balanced transmission line conditions. The transformer at the end of the beverage is designed to match impedance of the antenna.Ī two-wire bi-directional beverage requires the antenna element to operate a balanced transmission line, as well as a conventional long wire antenna. These are two beverage antennas receiving in opposing directions to share the same space. 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 antenna should be longer than 1 wavelength and installed at a height of less than 0,05 wavelength above ground.īeverage antennas provide one of the least expensive and most reliable ways to improve DX capabilities on the low frequencies.
The beverage is a long wire antenna installed very close to the ground.
