The Comet CAA-500 antenna analyzer is a professional class instrument for measuring SWR, resonance and impedance. It features a highly sensitive, high precision Yokogawa meter for measurement accuracy in seven ranges covering 1.8 to 500 MHz. Impedance is 12.5 to 300 ohms. VSWR 1:1 to infinity. Digital readout accurate to 1 kHz. The decimal point will blink when the batteries are low. An OVER LED indicates an out of range condition.
The CAA-500 will operate for up to 14 hours from six AA cells (not supplied). When the batteries become weak the decimal point will start blinking. It will also operate from an external 12 VDC source. A DC power cable is supplied. There is an SO239 input jack for Bands A – F and a female N for the High range.
