DIY CB Antenna
Making your own CB mobile antenna requires a basic understanding of the frequency used by CB send and receive radios. The wavelength of the 27-MHz CB band is a little over 17 feet, or 204 inches; to send and receive CB, use two halves of this standing wavelength, or two 102-inch lengths of copper wire. Insulate and ground these two lengths of wire, connect them to your CB radio, and then mount them to the highest convenient point on your vehicle.

How to Hook up a Wireless Mic & a Wireless Monitor
Like most wireless devices, the appeal of wireless microphones and monitors stems from eliminating some of the clutter caused by excess wires and having more mobility as you work. Most wireless microphones and monitors work along the same principle, using two transmitter/receivers. One is attached to the microphone or monitor. The other is connected to the computer, usually using a USB port. While wireless microphones are very popular, wireless monitors have yet to really catch on. This is probably due to wireless monitors' range limitations, as well as the fact that few people need to walk around the house with a monitor in hand.
