Homemade Base Station CB Antenna
- Check area for power lines and ensure that the antenna is not installed in the same vicinity. The distance feed line must snap before you come 20 feet close to any power line in case it does become airborne due to high winds or other causes. This means that the length of the antenna combined with the length of the line must come to less than 20 feet away.
Follow every safety precaution to the letter when doing this procedure. Many people are killed because of carelessness while doing this task and these deaths happen before the wire even hits the antenna. - Purchase a 50 ohm coaxial cable that will run from the CB radio to the antenna. Measure the correct distance before installing it. Cut one to four lengths of wire each 105 inches in length. These four lines will eventually be connected. Attach the lead wire of the coaxial cable to one 105-inch cut wire. The braided outer shield of the coaxial cable must not be touching the outer wire.
Attach this braided outer shield to between one and four pieces of wire that are pointing down to the ground. Tape the wires and cables ensuring that the four wires that are pointing down do not touch the cable that is pointing upward. Instead connect all of the wires to the braided outer shield of the coaxial cable. Use plastic-coated speaker wire, salvaged extension cords, or other similar wiring to make the vertical antenna section and ground plane wires. The type of material isn't actually that important as most will work fine. - Attach a plastic clothes hanger to the top of the antenna. Use scotch tape to secure it to a long wooden pole if that is your medium of choice. Use this pole to hang the antenna in a tree or wherever you intend to hang it. The clothes hanger will eventually come off as the tape loosens. This will allow the antenna to remain in the tree and the radial wires to dangle.
This is only one way to make a CB antenna. You can also have it grounded into your yard if it is prepared with gravel and a brick perimeter. A PVC pipe is secured into the ground and the coaxial wire is attached to the base with alligator clips. A wire element is run up the pipe and kept in place with scotch tape. The four wires are secured by bricks. This is a more complicated set up and perhaps more dangerous, but whichever approach you choose always use extreme caution.
