System and method for measuring fields over distance

A method comprising:

• obtaining, in a computing device, a plurality of field measurements from a corresponding plurality of metering devices while transmitting a wireless signal output using a Zenneck surface waveguide probe, the field measurements indicating the wireless signal output of the Zenneck surface waveguide probe;
• and
• generating a user interface for display using the field measurements, the user interface indicating a field strength over distance of the wireless signal output of the Zenneck surface waveguide probe;
• and
• generating a plurality of records with each of the metering devices, wherein each of the records includes at least one of the field measurements and a timestamp;
• wherein each of the metering devices includes a respective one of a plurality of clocks, wherein the method further comprises obtaining the timestamp from the respective one of the clocks.

A metering device, comprising:

• a passive multi-loop antenna;
• at least one amplifier;
• at least one bypass conductor;
• a field meter configured to generate field measurements at frequencies as low as 1 Kilohertz;
• and
• a meter controller being configured to generate a plurality of records, each of the records includes at least one of the field measurements and a timestamp, transmit each of the records to a remote computing device through a network, and alternatively couple one of the at least one amplifier and the at least one the bypass conductor between the passive multi-loop antenna and the field meter.
