Description

 SURECOM SA250  Colour Graphic Antenna Analyzer
132-173 / 200-260 / 400-519MHz

 checking, tuning or repairing antennas and antenna feed lines.
Mainly, these are S.W.R. (Standing Wave Ratio) and impedance measurement instruments (vector impedance analyzers).
Easy-to use measurement modes. make SURECOM attractive for professionals and hobbyists. It is quite important that graphical display of various parameters over a wide frequency range is a key feature of these analyzers which significantly reduces the time required to adjust an antenna.
