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.

These impedance transformer kits have been designed for the Do-It-Yourself (DIY) enthusiast and Instructor workshops on baluns and ununs for antenna matching and RFI use.

The impedance transformers are classified in ratios of 2:1 (100:50 ohm) to 16:1 (800:50 ohm).  The outputs can be configured as balanced (Balun) or as unbalanced (unun) with respect to the inputs which are considered all unbalanced coax at 50 ohms.  All impedance transformers are designed for 1.8-31 MHz unless otherwise specified.
