How to make homemade RF Bug Detector?

  • First, take all the material and place them on the work table.
  • Secondly, remove the ends of the 41-AWG enameled copper wire using wire strippers. After doing this, the two wires will be exposed.
  • With the 41-AWG, make a coil of 19 turns wire around one end of a toothpick. Do the rounds with one end of the copper wire.
  • Apply glue to the coil’s end. The glue must stick permanently. Run another end of the wire through a brass tube with a 0.09-inch diameter. Now strip another 0.5-inch wire starting from the tube end with the wire strippers.
  • Now connect 41-AWG copper to the BNC connector. There are two wires from the stripped wire. Solder one wire to + of the BNC connector and the other to the – contact of BNC connector.
  • Attach the BNC connector to the brass tube with epoxy and dry it. Apply glue to the cotton swab and rub on the outer side of the wire coiled around the toothpick.
  • Place a toothpick in the brass tube and push the glued wires to attach their sides to the brass tube, and let it dry.
  • Screw the BNC connector to the female BNC connector of the RF voltmeter and turn it on.
