Introduction
(Later improved model than this is here : Racetrack Tuner)
This is a capacitive coupler for tuning Short Loop Antennas (STL).
It is an evolution from the ‘Patterson Match’ aka military loop from 1967, this is my fifth generation of: Simplified Patterson Coupler
More build description and use here: Hexagon Coupler v1 from the blog Electromagnetic Adventures.
Needed material
- Printed model
- 5 cm wide copper tape
- 2 pcs Knobs (optional)
- 4 pcs small self threading screws
- 1 pcs BNC Connector
- 2 pcs banana female connector
Tools:
- M10 Threading tool - or modify model and print with threads
- Small drill
- Screwdriver
INSTRUCTION
(please contact me if instruction is unclear so I can improve)
Add copper tape to inner, outer and middle hexagon. Thread inner and outer hexagon.
Secure each shaft with disk and 2 self-threading screws.
Solder wires, add some foil to solder wire away from hexagons, Be careful and work fast to not melt 3D model:
- RFin
- Ground: to middle hexagon,
- Signal: to upper hexagon
- Loop antenna
- L1: Outer hexagon
- L2: Middle Hexagon
Tested only with 10W but it should be able to handle more, ensure that distance between foils are > 1mm and cut away excess to avoid short circuit
Warning❗
Keep away when in operation, use the protective cover, because when in resonance the voltage can be several 1000 volts and burn your fingers.
