- This Antenna Analyzer adopts black case would protect the antenna analyzer from external damage, in use. CONVENIENT OPERATION- operation buttons are easy and convenient to operate. You can selects operation mode, band and extended functions. FEATURE- The antenna tester is Powered by DC 12 to 14V 500mA external power with 2.1mm power jack(center pin positive), just connect the power and then work. The meter has compact size, easy to carry and store in your bag. WIDE MEASUREMENT RANGE- SWR usable measurement range of this analyzer is 1.0 to 9.99. step size: user configurable increments of 100Hz, 1KHz, 10KHz, and 100KHz. APPLICATION- Measure antenna electrical parameters: SWR, impedance (resistance and reactance), capacitance, inductance. It can measure feed-point impedance, ground loss, inductors and capacitors. Measure and determine optimum settings for tuning stubs: SWR, approximate Q, resonant frequency, bandwidth, impedance. Coaxial Cable Loss, Determine antenna tuner loss, Estimate quartz crystal parameters. Colour: Black material: metal Package Contents: 1 x Antenna Analyzer Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is 1-3cm. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
