Product summary: The M² FGBL1200 is a 4:1 current balun rated for 3 kilowatts of power. It is designed for HF operation and provides impedance transformation between balanced and unbalanced feed systems.
Key characteristics
Transformation ratio: 4:1 Converts a 200-ohm balanced load to approximately 50 ohms unbalanced, or the reverse.
Power rating: 3 kW continuous duty.
Frequency range: 3 to 30 MHz (typical for HF use).
Construction: Heavy-duty ferrite core design with weather-resistant housing.
Connector type: N-type coaxial connector.
Purpose and application
This balun matches antennas with a higher feed impedance such as folded dipoles or certain log-periodic arrays to standard 50-ohm coaxial feed lines. It also helps suppress common-mode currents, ensuring proper feed line balance and reducing RF interference.
The FGBL1200 is well-suited for high-power amateur radio stations or commercial HF systems that require both impedance transformation and current balance.
