Product Details

Add a ferrite filter to the digital ballast AC line input and ballast cord output and suppress ugly interference to surrounding electronic devices (yours and your neighbors)! Order 1 set for each ballast.

You get a ring filter (1.4" ID) for the AC power line and a snap on filter (3/4" ID) for the lamp cord. Wrap as many turns as possible on both cables as close as possible to the ballast.

Ballast shown is a Lumatek LK400.

All ballasts in a particular location must have a filter otherwise RFI may not be suppressed to a measurable value. Suppresses RFI in range of .15-10 MHz.

2:1 (100:50) Baluns are useful between 50 ohm coax and 100 ohm balanced lines for loops, cubical quads, log periodics and other antennas where the impedance at the end of the feedline is 100 ohms (1/2 wavelength feedline).
