More info

The AA-55 Zoom analyzer is designed for measuring SWR (Standing Wave Ratio), Return Loss, Cable Loss, of cable and antenna systems from 60 kHz to 55 MHz. 

A built-in ZOOM capability makes graphical measurements especially effective. 

An integrated Time Domain Reflectometer mode can be used to locate the precise location of a fault within the feedline system. 

The following tasks are easily accomplished by using this analyzer:

  • Rapid check-out of an antenna
  • Tuning an antenna to resonance
  • Comparing characteristics of an antenna before and after specific event (rain, hurricane, etc.)
  • Making coaxial stubs or measuring their parameters
  • Cable fault location
  • Measuring capacitance or inductance of reactive loads

AA-55 ZOOM differs from previous models in that it has:
· Enlarged 3.2 inch color TFT display (320×240).
· Scanning speed has increased over AA-54.
· Large waterproof keypad keys.
· Same dimensions as our AA-30/54/170.
