01
Antenna and feed
The antenna type, feed arrangement and intended installation establish the starting point.
CUSTOM BALUNS & COMMON-MODE CHOKES
Built around
your antenna system.
DX Repair builds custom baluns and common-mode chokes using genuine Fair-Rite cores and the requirements of your station.
A useful build starts with the antenna, feed arrangement, operating bands, transmit power, duty cycle and connector requirements—not a one-size-fits-all label.
WHAT WE DO
Start with the application
Share how the feed line is used and what the finished build needs to handle. We confirm the specifications and price before proceeding.
02
Bands and power
Frequency coverage, transmit power, modes and duty cycle help define the magnetic and thermal requirements.
03
Connections and enclosure
Connector preference, weather exposure and mounting details shape the finished assembly.
THE DX REPAIR APPROACH
The details make the difference
Custom work lets the core, winding and mechanical package follow the station instead of forcing the station around a generic part.
Genuine materials
Genuine Fair-Rite cores are used for the agreed application.
Clear specifications
The planned build and connections are confirmed before fabrication.
Independent service
DX Repair is an independent builder and is not affiliated with equipment manufacturers.
