Here's a simple and elegant solution to keeping common mode currents off your coaxial cable feed line. According to Australian radio amateur Peter Parker (VK3YE), this basic choke "balun" only uses a few materials: 7 meters/22.96 feet of RG-58 coaxial cable. 75mm/2.95 inches diameter piece of PVC tubing.
