Product Description


SURECOM-HK are powerful antenna analyzers designed for testing, 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, as well as additional features such as connection to a personal computer (to plot Smith charts, etc.), 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.

Main Features: 

  • 2.2 ” precision LCD screen,High-lumen LCD brightness, easy to read in direct sunlight
  • Heavy duty Aluminum enclosure,strong anti-interference ability.
  • Very compact and convenient for field use
  • Built-in rechargertable battery
  • Full Band control by knob ( 132-173Mhz / 200-260Mhz / 400-519MHz)
