Product Details
MPN: RFI-GEN-3
Type: New
Country/Region of Manufacture: United States
Filter Power Rating (PEP watts): power rating of cable
RFI Suppression Range (MHz): 1-300 MHz

The RFI generator kit includes 2 ring filters with 3 inch inside diameter for 2 or more turns of AC/DC generator cable at generator and another 2 or more 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 less than 1/2" diameter, consider the RFI-GEN-1 generator filter with a 1" inside diameter.

Note: generator cable not included.

16:1 Baluns are useful between 750-850 ohm balanced loads where the impedance at the  end of the feed line is 800 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

16:1 Ununs are useful between coax and long wires with a load impedance near 800 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 16:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
