Specification: AW07A 160M HF/VHF/UHF Impedance SWR Antenna Analyzer Meter Brief introduction: AW07A antenna analyzer is a compact battery powered RF impedance analyzer. It can test the SWR status of your antenna, measure the impedance and reactance component and help you to solve antenna problems. This unit combines six basic parts: a variable oscillator, frequency counter, independent oscillator, 50 ohm RF bridge detector, an A-D converter, and microcontroller. This compact product was built to feed the need for the solid construction and field test. The operating frequency range of this unit goes from HF, and extends up to 490MHz. It is specially designed for analyzing 50ohm antenna system. It measures RF impedances from a few ohms to several hundred ohms. The AW07A is also an L/C meter, measuring the values of capacitors and inductors. Additionally, it could be a non-precision signal source and frequency counter. With a built-in RF strength meter, it tests the RF field strength near your antenna system, and its very useful when you need to know the RF interference status around your station. The AW07A also functions as a non-precision signal source and frequency counter. The operating frequency range of this unit extends from 1.5 to 71 MHz in six overlapping bands, and includes SWR measurements on 85-185MHz , 300-490 MHz.
