1:4 Balun, ON6MU
Balun for folded dipoles

4:1 balun for 160 to 10 meters
Here we calculate the half wave length of the matching section of the 4:1 coax balun

4:1 coax balun design CALCULATOR
Here we calculate the half wave length of the matching section of the 4:1 coax balun

50 ohm single-band baluns
The balun herein described is suitable for 50-ohm monoband antennas which can often represent a valid choice

JI -Test, measure balun, and compare antenna baluns or balums
Many articles and technical sources on baluns or balun design ignore voltage, focusing only on current. Focusing only on current is a serious oversight that can result in defective system design
