Examples are resistors used to replace antennas, batteries, loudspeakers, or the like. Includes single port terminations of twin lead, coaxial and waveguide transmission lines as low power terminations of a section of a transmission system in a specified manner. Includes dummy loads when arranged in a group or bank. Excludes power absorbers. See also LOAD BANK, ELECTRICAL.
