Comet Antenna Analyzer
CAA-500MARKII
CAA-500MARKII SWR/Impedance Analyzer
Highly accurate analog cross needles display SWR and impedance simultaneously.
Full color TFT LCD display screen provides graphic and numerical SWR along with total impedance with R and X values.
Features:
AUTO SWEEP MODE
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.
MANUAL SWEEP MODE
Choose the band, manually set the band-width you desire, then manually sweep the chosen frequency range.
MULTIPLE MANUAL SWEEPS
Should you want to make an adjustment to the antenna length, the position, height above ground, a gamma match adjustment, etc… you can overlay multiple manual sweep results in 5 different colors! Instantly graph and see exactly what happened after each adjustment!

The CAA-500MarkII is the primary tool for any antenna adjustment or diagnostic project.
Specifications subject to change without notice
CAA-500 manual sweep mode
Press the “Sweep Center” button and the analyzer automatically sweeps the entire pre-set band that you have selected, in this case the 2M band.
CAA-500MarkII manual sweep mode
In the manual sweep mode, the center frequency (in this case 146MHz) and the bandwidth (in this case +/- 3MHz) 143-149MHz have been set manually.
The SWR is graphed by manually turning the frequency knob.
Adjustments to the element length, gamma match, height above ground, location, etc… can then be made, and by turning the frequency knob a new SWR graph in a new color, is overlaid onto the original graph to illustrate the change to SWR.
Each adjustment can then be graphed as may times as desired, in up to 5 different colors.
CAA-5SC
Padded nylon soft case protects the CAA-500 or CAA-500MarkII SWR/Impedance analyzer from damage.
- 1/4″ foam padding
- Nylon Tricot fabric resists tearing
-
Front panel protective panel Velcros in place (not shown)
-
Shoulder strap and belt loop included
The CAA-500/CAA-500MarkII are sensitive test instruments, the CAA-5SC protects the case and meter lens from damage caused by accidents or everyday wear and tear.
