Simple antenna current meter

Just spotted this on the web. Looks like a useful idea to indicate antenna current and could not be simpler.

Don't forget to shunt the captor coil of the toroid, with a low value (100 ohms) resistor. To avoid to choke the RF. Some cores take temperature, with only 5 W.
