Line stretchers with a very low SWR and a uniform characteristic impedance of 50 OHM. Especially useful for eliminating the usual Smith-chart corrections for length of line between unknown and impedance-measuring device. Also useful as impedance-matching transformers and phase-adjustment elements in coaxial systems. Most useful at frequencies above that for which the length of adjustment is a half wavelength. 50 OHM impedance, locking GR-874 connector. Sourced from military surplus lots.
