CAA-500MarkII analog and graphic antenna analyzer
CAA-500MarkII analog and graphic antenna analyzer

  • New color TFT Display in addition to Analog meter of original CAA-500.
  • Display of absolute value of Reactance (X) part of impedance.
  • Manual and Automatic SWR Sweep modes, with multi-color traces (5) during manual sweeps to show the effect of adjustments to the antenna under test.
  • Auto Power Off feature to preserve battery life.
  • Power options including Alkaline or rechargeable NiMH batteries; trickle charging is available via the DC jack on the left side panel.
The NEW CAA-500MARKII Commercial Grade SWR/Impedance Analyzer is finally arriving from the Comet factory in Japan!
The new analyzer retains the same analog cross needles to display  SWR and impedance, but ADDS a full color TFT LCD display screen providing graphic and numerical SWR along with total impedance with R and X values.
Automatically graphs the SWR on the LCD display.   Choose any one of the pre-set amateur band frequency ranges and press the sweep button…in about 30 seconds the SWR graph is completed and displayed.
Choose the band and manually set the band-width to be swept and manually sweep the chosen frequency range.
Should you want to make an adjustment to the antenna length, position, height above ground, gamma match adjustment, etc…you can overlay 5 manual sweep results in different colors!  Instantly graph and see exactly what happened after each adjustment!
