Reference current draw by power level for supply sizing.

Radio ClassTX PowerTyp Approx Current
Handheld5 W1.5–2.5 A
Mobile FM50 W10–14 A
Base HF100 W20–25 A
SWR TargetFormula

SWR = (1 + |Γ|) / (1 − |Γ|); aim for ≤ 1.5:1 at center frequency.

GroundingSafety

Station ground and antenna ground must meet local electrical code — consult ARRL grounding guide.

  • Buy a SWR Meter Early

    Even a basic meter saves radios from high-reflected-power damage.

  • Label Coax Runs

    Mark band and length at both ends — simplifies future troubleshooting.

  • Avoid Cheap Power Supplies

    Switching supplies without RF filtering can raise noise floor on HF.

Safety Notes

  • Never transmit into an open or damaged feedline — reflected power can destroy finals.
  • Disconnect power before changing antennas; capacitors in tuners can retain charge.
