BUY THIS KIT NOW TO SOLVE YOUR RFI ISSUES AND REDUCE COMMON MODE RECEIVER NOISE LEVELS FOR YOUR ICOM 9700 VHF/UHF RADIO. ALSO WORKS WITH MANY BRANDS OF HAM/COMMERCIAL HF RADIOS WITH SIMILAR FREQUENCY RANGES.

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 .15-2000 MHz range. DC filter effective from .15-10 MHz, Snap On filters effective from 1-500 MHz and 200-2000 MHz identified for easy installation on selected antenna and I/O cables.

The ferrite split beads and ring 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 1 AC/DC noise reduction ring filter and 11 snap on filters for coax and I/O cables. Quick installation - immediate RFI/noise reduction. No radio mods required.

If you use a linear amplifier use a Palomar Engineers amplifier RFI kit for additional RFI interference suppression.

Also make sure you connect a good RF ground to the transceiver ground post.

Note to Flex Radio users:  Use snap on ferrites for firewire cable, speaker cable and mic cable,  Ring ferrites for Antenna output and DC power.

For additional RFI suppression, use a feed line choke at the antenna to suppress common current on the coax feed line – see our store for feed line choke alternatives for use at the antenna.

 

If you use a linear amplifier we have RFI kits for linear amplifiers that help suppress RFI in your shack or in your neighbor’s house.
