Citizens' band radios -- also called CBs -- are radios that broadcast and receive on public air waves. CB radios are used for long-distance trucker communications and for monitoring and talking on home-based stations. Make an antenna that will pick up the signals to boost the receiving and broadcasting range of a base station.
Lay four of the 105 inches in length wires on a flat surface. Set them out so they form an eight-pointed circle. Twist the wires in the centre so they are twisted together and have four points of contact to stand on.
Twist the remaining wire to the centre hub so it stands up in the middle.
Attach the ohm cable to the cable with the screw attachments on the back of the CB radio. Split the cable down the middle and use the cutting tool to remove the rubber casing at the end to expose the wires. Screw the wires to the setscrews at the antenna marking on the CB.
Run the ohm cable to the antenna wires. Wrap it to the centre of the wire antenna and secure with black electric tape.
Place the antenna outside the room where the base station is held. Run it out a window, if necessary, to keep it attached to the radio.
