Clamp-on RF Meter Documentation
A clip-on RF ammeter is not only useful for antenna experimenters but also as an aid to achieving good EMC in an amateur station. If some of the RF current from a transmitter flows into mains wiring, this can increase the chance of breakthrough problems in nearby TV, video or audio equipment etc. A clip-on RF ammeter allows this current to be measured, so that steps can be taken to minimise it. For EMC investigations, you can also clip this meter on to coaxial cables, rotator cables and other wiring in your shack, to find out where the RF currents are flowing, and how big they are. You can also use this tool for measuring currents in wires and radials.
