If you have a high end radio with multiple antennas, and more than 3 I/O cables, use our Deluxe Transceiver RFI Kit, RFI-XCVR-DELUXE
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 snap on 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 AC/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.
Included are the following chokes and installation guidelines:
RF Input/Output: 1.4" ID ring filter – 5-9 turns of RG-58/RG-8X size coax cable through center
AC/DC Input: 1.4" ID ring filter – 3-7 turns of AC/DC power cable through center
3 additional I/O cables - 1/2" snap on with 1-2 turns through center. Multiple wires can share the same filter.
For additional RFI suppression, use a feed line choke at the antenna feed point to suppress common current on the coax feed line.
If you use a linear amplifier use an amplifier RFI kit for additional RFI interference suppression.
