Variable Capacitor V2 Square Design

For Magnetic Loop Antenna or Tuner (25-155 pF)

I only work with qrp and I tested it with qrp. I did not test it with high wattage transmission. Considering that it may get hot during transmission with high wattage, it may be more beneficial to print with ABS.

Required Parts:

t8 trapezoidal shaft x1 22cm
t8 trapezoidal nut (8 pitch)
induction spindle 6mm x4 21cm
608 bearing x2
8-5 coupling
aluminum tape
I use the coupling as an adjustment knob. Can be added via nema17 motor coupling for remote control
