Priced at only $80, the portable RF Meter is a low-cost signal-strength measurement tool for designers of RF radio systems. Two models are available to detect signals at 315 MHz ...

To wit, we present this PKE meter-style WiFi scanner. Of course, [Kevin McAleer]’s project is strictly in the “Just for Fun” category. But that doesn’t mean it’s not at least somewhat ...

The ubiquitous signal strength meter has likely fooled everyone that uses a smartphone at one point, because it’s really not a very good indicator of your actual signal strength.

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...

Debuting as the industry's first portable tensile strength pull tester for coaxial connectors, the MPT-100 meter provides up to 200 lb. of force to perform ratchet-action destructive ...

It is not unusual to find stations with field strength meters whose last calibration was four or five years ago, although most meters are surprisingly stable and hold their calibration very well. It ...
