Product Information
  • Overview
  • Description
The DXE-FCC050-H05-A Feedline Current Choke, using Maxi-Core® technology, prevents unwanted RFI by eliminating feedline current and radiation in 50 Ohm, coaxially fed antenna systems. It provides excellent feedline decoupling and low loss performance from 1 to 60 MHz and is power rated for 2 kW continuous, 5 kW intermittent.

The FCC has significantly higher common mode impedance and a larger effective core area than similar line isolators, including conventional enameled wire or bead baluns.
This results in:
- Higher power handling with lower loss - more power to the antenna
- Improved antenna bandwidth - easier on the radio
- Reduced RFI - less interference to and from your radio
- Compensation for a less than optimal ground system

While most common advice is to improve the station's RF ground, the root of the problem is in the poor isolation of the feedline from antenna currents. In other cases, as the coax feedline travels through the near-field of the antenna, the current can be re-introduced to the feedline after the balun. If your SWR is already low and you wish to reduce feedline radiation (RFI) and improve reception, an FCC is recommended.

The DXE-FCC050-H05-A Feedline Current Choke is designed for use with coaxially fed, 50 Ohm antennas of many varieties including verticals with elevated radials. It is rated at 2kW.
