Icom A120 VHF Aircraft Transceiver RFI Kit - 2 Noise Reduction FiltersProduct DetailsMPN: RFI-ICOM-A120Type: NEWCountry/Region of Manufacture: United StatesFilter Power Rating (PEP watts): = Cable RatingRFI Suppression Range (MHz): 1-300 MHz# Ferrite Filters: 2Enclosure Size (inches): n/aTypical Use:: DC power, Antenna CoaxBUY THIS KIT NOW TO SOLVE YOUR RFI PROBLEMS! WORKS WITH MANY BRANDS OF COMMERCIAL VHF RADIOS INCLUDING ICOM A120, A220, A220T.
Quick installation - immediate RFI/noise reduction. No radio mods required.
This kit will help reduce or eliminate:
1. Radio Frequency Interference (RFI) to electronic devices including instrumentation and GPS systems.
2. RFI from other electronic devices such as switching power supplies, LED instrument and cockpit lights, battery chargers, GPS and computer systems which generate common mode currents on your radio interface or coaxial antenna feed lines.
3. These filters help reduce SWR problems between transceiver and 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 split bead (they snap on like a clam shell) filters for coax and AC/DC power/ standard 15 Pin connector cable. 3/4" whole ID - just wrap 2-3 turns of coax cable thru 1 bead and 2-3 turns of the DC power/15 Pin cable thru the other split bead. Does not affect signals carried by the cables, only the common mode interference noise is suppressed.
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.

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
