Got an electronic interference problem on your boat or RV? Do you hear HUM-BUZZ-NOISE when you use the fish finder/radar/GPS/Generator or hear your voice on the stereo speakers when you transmit on the radio? Maybe you heard buzzing or humming when you turned on the battery charger/inverter/generator – any of these symptoms indicate you have RFI issues on your boat or RV and you need to stop it or the HUM-BUZZ-NOISE may drive you nuts!
But you don’t have to worry – We got the fix for you – lots of filters, all in a small box, that are easy to install on the wires of your electronic stuff that is bothered by the RFI.
If you have RFI, you need this kit:

Boat Owner’s Electronic Interference Suppression Kit Use this filter kit to suppress interference noise between electronic devices on your boat including: radar, fish finders, audio/video systems, inverter noise, solar controllers, vhf radio, marine/ham radio, auto pilots, electronic gauges, PA systems, and many other electronic devices. |
What is included:
A total of 17 Ferrite Ring/Snap-On Filters
Ring: 1.4” ID x 6, Snap on: 3/8” ID x 6, 1/2” ID x 5
Mix 31 Interference Range: 1-300 MHz
4:1 impedance transformers (Baluns and Unun configurations) are available in kit form or assembled form in a weatherproof Current Unun and Balun Enclosure which we call CUBE Baluns™ and CUBE Ununs™. All 4:1 impedance transformers use ferrite cores and the kit forms can be configured as a balun with balanced output of 200 ohms or as ununs with one side grounded.
4:1 baluns are designed for 50 ohm unbalanced (coax) input to 200 ohm output (either balanced or with one side grounded).
4:1 Baluns are useful between balanced lines for center fed Zepps, Off-center fed (OCF) dipoles with coax, G5RV antennas, full wave loops, NVIS dipoles that are close to ground and have impedance levels near 200 ohms or high impedance feeds for log periodic beams.
4:1 ununs are useful between coax and vertical antennas, monopole verticals or long wires with load impedances near 200 ohms.
