KIT 20 rotors Butterfly capacitor
5 X 250mm M5 Threaded Rods 21 sets of 1mm pcb rotor + stator + stator for capacitor 100mm X 80mm M5/M5 rubber coupler 28BYJ stepper motor at 5V Base set + base + 1.6mm pcb motor base Assembled and programmed stepper motor driver 120 aluminum spacers of 4m M5. Inner diameter 5.1mm, outer 8mm Box for electrical assemblies 241X180X95 50 brass washers 50 M5 brass nuts 10 lock nuts SHIPPED UNASSEMBLED With this capacitor, values of 12pF to 150pF are obtained. If use a 1.40m diameter loop antenna (4.40m perimeter), it is almost guaranteed to resonate and have a SWR of less than 1:1.5, in the 17m-20m-30m-40m bands. A 4.40m loop and a small 88cm coupling loop are recommended.
