BUY THIS KIT NOW TO SOLVE YOUR RFI/EMI ISSUES - WORKS WITH MANY BRANDS OF HAM/COMMERCIAL HF RADIOS. Deluxe RFI Filter Kit for HF Radios with multiple antennas, computer interfaces, audio I/O lines.
Kit Includes 1 noise reduction ring filter antenna coax connector, AC power and three 1/2" snap
on filters for I/O cables covering RFI range of 1-300 MHz.
Quick installation - immediate RFI/noise reduction. No radio mods required.
Purpose
The RFI kit is designed to be installed on your radio transceiver to reduce Radio Frequency Interference (RFI) caused by common mode current on the outside of the coax braid at the output of your radio and AC/DC power cable. Additional chokes are included to reduce common mode currents on 3 more transceiver cables including computer control, audio and another.
This kit will help reduce or eliminate:
1. “Hot mic” RFI caused by poor grounding of antennas or common mode currents from linear amps feeding unbalanced (coax fed) antennas without baluns/line isolators.
2. RFI to neighbor’s electronic devices including audio/video systems, computers, telephones, garage door openers, etc.
3. RFI to your other radios, audio/video systems, computers, telephones, etc.
A side benefit is a reduction in noise floor in your receiver depending on the amount of noise being introduced by common mode currents (which are blocked/reduced by the chokes in this kit).
These chokes use a special mix of ferrite core material that is effective in suppressing radio frequency interference from transmitters and high noise floor on receivers.
The split beads beads are easy to use, don’t require modification of the protected equipment and work in almost all cases, even when plug-in filters fail.
Use of the chokes often helps cure SWR problems between transceiver and a linear amp and between transceiver and antenna tuner or direct to antenna. The DC power line choke helps keep common mode current out of the power line which could cause interference to other devices connected to the same power line if not suppressed.
If you use a linear amplifier buy an amplifier RFI kit for additional RFI interference suppression.
