Ferrite filter products can help speed up digital devices by suppressing common mode current from RFI sources OR prevent digital devices from emitting RFI on its connecting cables and power supply lines.

This kit will help reduce or eliminate:
1. Radio Frequency Interference (RFI) to electronic devices including audio/video systems, computers, telephones, garage door openers, alarm systems, and home appliances, in your house or your neighbor’s house.
2. RFI from other electronic devices such as switching power supplies, LED and fluorescent lights, battery chargers, Ethernet cables, solar systems, kitchen appliances, and cable/satellite TV systems which generate common mode currents on your radio cables.
3. These filters help cure SWR problems between transceiver and a linear amp and between transceiver and antenna tuner or direct to antenna. The DC power line filter helps keep common mode current out of the power line which could cause interference to other devices connected to the same power source.
These chokes use a ferrite core material that is effective in suppressing RFI from transmitters and receivers experiencing a high noise floor in the 1-300 MHz range.
The ferrite split bead filters are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.
Kit Includes 2 noise reduction snap on filters for coax and AC/DC power and 1 snap on filters for I/O cables. Quick installation - immediate RFI/noise reduction. No radio mods required.
Suggested use: DC supply cables: 3-4 turns thru center of snap on filter. RF Output: 3-4 turns of RG8X size cable thru center of snap on filter. ACC1/ACC2 outputs: 2-3 turns thru center of snap on filter.
For additional RFI suppression, use a feed line choke at the antenna feed point to suppress common current on the coax feed line during TRANSMIT and a CMNF-500-50 coax noise filter at the radio end of the coax to reduce common mode noise during RECEIVE.
If you use a linear amplifier use a Palomar Engineers amplifier RFI kit for additional RFI interference suppression.
Check out the ELECRAFT-RFI-KXPA100 RFI KIT if using that amplifier.
