That is, you must multiply the reading by 4 when measuring microwaves at that high a frequency. Sensitivity is low by 50% (-3 dB) at the frequency limits. Unlike other low-cost field strength meters, this meter’s frequency response does not depend on the characteristics of an external antenna the internal detection system yields a flat response over a very wide range of frequencies.Īccuracy in the FM, TV and cell tower frequency range (30 MHz – 2.4 GHz) is +/-25%. The meter reads true power density directly on the display. This is an extremely sensitive meter which can accurately measure RF background even in rural areas far from any transmitters. 5 MHz to 3 GHz, and expresses the field strength as power density (.001 to 2000 microwatts/cm 2). Technically a “power density” meter, the RF Field Strength Meter detects the electric field of radio and microwaves (RF) from.
