●The CA-500 MarkII has a wide-range signal oscillator covering 1.8-500 MHz, enabling measurement of important antenna system
parameters including impedance and Standing Wave Radio (SWR).
●The dual analog meter, combined with the LCD display, allows simultaneous display of SWR and impedance.
● The color TFT display permits easy viewing of frequency and band information, even in the dark.
●The Band Sweep function allows you to measure SWR across the selected ham band and view it on the display graph.
You can also define a center frequency and frequency span for display of the SWR characteristics.
●The programmable Auto Power Off function preserves battery capacity in case you forget to turn the meter off.
●You can use 6 AA alkaline or Nickel-Metal Hydride (NiMH) batteries to power the meter. Up to ten hours of operation
are possible using alkaline AA cells.
●External 8-16V DC power may be used to power the meter; this also allows trickle charging of a NiMH battery.
●A hand strap is provided, for ease of use and to minimize the chance of dropping the CA-500 MarkII.
