Why are short, heavy-gauge wires used for a transceiver’s DC power connection?
To minimize voltage drop when transmitting✓Respuesta correcta
To provide a close match to the power supply output impedance
To avoid RF interference
To minimize radiative losses in the power cable
Explicación
A transmitting radio can draw ten or more amperes, and any resistance in the DC cable turns that current into a voltage drop at the radio. Short, heavy-gauge wire has low resistance, so the radio keeps its full supply voltage on transmit peaks.
