If the load resistor was connected directly across the voltmeter input terminals, the current through the relay contacts would cause a voltage drop and the measured cell voltage would be in error.
The affection of parameter variation of down lead wires and top loading wires on effective height, radiation pattern, input reactance, radiation resistor and static capacitance is discussed.
同时研究了引线及顶线的各项参数变化对天线的有效高度、增益、输入电抗、辐射电阻及静电容的影响。

Thus, the output voltage is a measure of input current, and overall sensitivity is determined by the feedback resistor RF).
