• A = 3/4 λ
• B = 1/4 λ
• C = adjust to 50 Ω wave impedance between solder joints
• D = 4 turn balun to keep coax line from becoming part of the radiator

TODO

• describe how to fine-tune C

• HAM Operators use SWR-Meters, these show the overlay-ratio between in- and out-flowing wave.
• An SWR ratio lower than 1:1.5 is ok. 1:1 is perfect
• Sadly you need an transmitter to use this methode (you may ask a nearby HAM)
• SWR-Meters for 2-meter/70-cm band cost about 50€ for a cheap one
• The Cheap CB SWR-Meters are only useful for 11-Meter band

• Nibble away bits on both arms while maintaining the (3/4 λ) / (1/4 λ) ratio.
