Product Details

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.

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.
