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.
A few connectors.

Be sure to weatherproof the assembly.
