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 1:1 balun kits are current baluns. They consist of five large ferrite beads (total length 5-1/2 inches) that slip over the coax (but BA-8 and BA-58 will not slip over the connector). 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.
Model BA-8. For use with RG-8, RG-213, 9913, LMR-400 and similar cables up to 1/2 inch diameter. Balun diameter 1 inch. Requires 9-1/2 inches of cable for installation. For use from 3.5 to 1000 MHz. For 160 meters use two baluns.
Model BA-8……………$18.95 + $8 S&H. Tax in Calif.
Note: $8 S&H is “per order”. Order more than one and S&H is still $8.
Model BA-58 For use with RG-58, RG-8X, LMR-200 and similar cables up to 0.24 inch diameter. Balun diameter .6 inch. Requires 9-1/2 inches of cable for installation. For use from 3.5 to 1000 MHz. For 160 meters use two baluns.
Model BA-58………….$10.95 + $8 S&H. Tax in Calif.
Connector already on cable? Don’t want to remove it? Use split beads that clamp onto the cable.
For 1/4″ cables (RG-58, RG-8X, LM-200) use five FSB-1/4 split beads to get the same performance as the Model BA-58 balun kit.
Five FSB-1/4 @ $2.75 each …….Order Kit 105…….$13.75 + $8 S&H Tax in Calif.
For 1/2″ cables (RG-8, RG-213, 9913, LM-400) use five FSB-1/2 split beads to get the same performance as the Model BA-8 balun kit.
Five FSB-1/2 @ $5.50 each……..Order Kit 110………..$27.50 + $8 S&H Tax in Calif.
The beads clamp securely to the cable and may be operated as is. However, it is strongly suggested that they be covered with tape or coax seal to protect the beads from weathering and ensure long life.
Want a really neat installation? Use our kit that is complete with beads and shrink tubing to weatherproof them and hold them securely on the cable.
Model BA-8C for 1/2″ cable……………$34.95 + $8 S&H Tax in Calif.
