Here's a handy device that will keep rf off your coaxial cable feed line. PD1AIV has done an excellent video tutorial covering the basic tools, materials, and construction practices needed in making an "ugly balun" or RF choke suitable for 8o through 10 meters. You will need around 19 to 21 feet (5.49 to 6.40 meters) of 50 ohm coaxial cable plus fittings to make the choke. PVC pipe, screws and nuts, and a few connectors will be all you need to complete this project.
