COMTEK COM-LI-11140 Line Isolator is based on the Jerry Sevick, W2FMI design to prevent unwanted RFI in 50 ohm, coaxially fed antenna systems providing excellent feedline decoupling and low loss performance from 1 to 60 MHz. Power-rated for 2 kW continuous, 5 kW intermittent duty, with significantly higher common mode impedance and a larger effective core area than similar line isolators, including conventional enameled wire or bead baluns.

Benefits:
- Higher power handling with lower loss – delivers more RF power to the antenna
- Improved antenna bandwidth – easier on the radio and tuner
- Compensate for a less than optimal ground system – stop feedline radiation
- Reduced RFI – less interference to and from your radio

If you are having trouble with RF interference, such as disturbing audio, video or computer equipment in your house or your neighbors', a "hot" mic or audio distortion while transmitting, then it is likely that your feedline is acting like part of your antenna system. While most common advice is to improve the station's RF ground, the root of the problem is poor isolation of the feedline from antenna currents.
