AC/DC Generator RFI Noise Filter Kit = 1" ID - 2 filters
The RFI generator kit includes 2 snap on filters with 1 inch inside diameter for 1-2 turns of AC generator cable at generator and another 1-2 turns through center at the end of the generator cable near the powered device. The filter near the generator isolates generator power cable and prevents it from acting as an RFI antenna (generator source) and the filter near the powered device prevents the powered device from using the generator cable as an RFI antenna.
Use 2 or more turns through the filter for higher RFI suppression than a single turn (2 turns is 4 times the suppression as 1 turn, 3 turns is 9 times a single turn, etc.)
If you have a generator cable larger than 1/2" diameter, consider the RFI-GEN-3 generator filter with a 3" inside diameter.
Note: generator cable not included.
To address separate solutions we have developed two separate RFI kits: one for HF (1.8-300 MHz) mobile installations and another for VHF/UHF (30-1000 MHz) mobile installations. Each kit uses the appropriate ferrite mix for the frequency range desired.
