Which of the following direct, fused power connections would be the best for a 100-watt HF mobile installation?
To the battery using heavy-gauge wire✓Bonne réponse
To the alternator or generator using heavy-gauge wire
To the battery using insulated heavy duty balanced transmission line
To the alternator or generator using insulated heavy duty balanced transmission line
Explication
A 100 watt HF transceiver draws roughly 20 amperes on peaks, and heavy-gauge wire run directly to the battery keeps the voltage drop small so the radio does not brown out during transmit. Connecting at the battery also puts the load across a very low impedance source that helps filter alternator noise. The connection must still be fused close to the battery.
