Feature 1 Professional antenna analyzer A compact RF impedance analyzer. 2 It can test the SWR state of your antenna, measure impedance and reactance components. 3 SWR value from 1 to 9.9. 4 L/C meter It's also an L/C meter that measures the values of capacitors and inductors. 5 This analyzer acts as an inexact signal source and frequency counter.Note: 1. Please note that this product needs 8 * AA batteries, which are NOT included in the package. 2. Please allow slight error due to manual measurement. Thanks for your kind understanding.
