Baluns are used to connect balanced antennas to unbalanced transmission lines (coaxial cable). They prevent antenna currents from flowing down the outside of the cable. They should be located right at the antenna. They can also be used as “line isolators” anywhere along the cable to prevent the flow of induced RF current. |

|
Palomar balun kits are 1:1 current baluns. They consist of large ferrite beads (total length 5-1/2 inches) that slip over the coax. Also included are three lengths of shrink tubing to enclose the balun and hold it in place on the cable. The baluns work from 3.5 to 1000 MHz and allow use of RF power to the full capability of the cable. No tools are required for installation, just a source of heat to shrink the tubing. Use a heat gun, lighter, or matches. |
