5 Tips for Matching Dipole Feed Impedance with Your Transmission Line
To match dipole feed impedance with your transmission line, 1) Use a 1:1 balun for balanced 50Ω conversion (reducing common-mode currents by 20dB), 2) Trim dipole length (±2% of λ/2) to achieve VSWR <1.5:1, 3) Elevate antenna ≥λ/4 above ground to minimize impedance shifts, 4) Deploy a matching network (LC circuit) for multi-band tuning (1.8-30MHz), […]
