Field strength meter circuits
WebJan 30, 2009 · Again, you have to know which type of antenna that the field strength meter is using. Let's assume it is a half wave dipole. Field strength uses units of volts/metre and when we measure it we are measuring the RMS value. If your field strength meter is calibrated to read voltage in absolute terms, then E = K x Vr WebThere are two general methods available for determination of RF UHF field strength meter circuit. One is the standard antenna method. In this, use is made of an antenna in which the relationship between the field strength of the radio wave and the equivalent voltage that the wave induces in the antenna. The field strength is then determined by ...
