Balun ratio 1:6 (50 => 300 ohms) to go from a 50 ohm coaxial cable to a twin-lead 300 ohm bifilar line, max. 1000W PEP. Real HF ferrite toroid and SO-239 connector
Balun ratio 1:9 (50 => 450 ohms) to go from a 50 ohm coaxial cable to a twin-lead 450 ohm bifilar line, max. 1000W PEP. Real HF ferrite toroid and SO-239 connector
Voltage Balun ratio 1:1 (ex: 50 => 50 ohms). Maximum power: 1000 W PEP, to make "inverted V" dipole antennas. Robust aluminum body diameter: 5 cm (thickness: 2mm), real HF ferrite toroid and SO-239 connector.
Dipole 1/2 wave 1.8 MHz length : 83 m. Robust 60 mm diameter aluminum balun with SO-239 connector (female PL) and insulators at the ends + CHOKE BALUN integrated.
24 MHz/2 element monoband Yagi antenna, space-saving, combining performance and robustness of construction. "All grounded" design greatly reducing atmospheric QRM in reception (static). Easy adjustment by gamma-match.
21 MHz/2 element monoband Yagi antenna, space-saving, combining performance and robustness of construction. "All grounded" design greatly reducing atmospheric QRM in reception (static). Easy adjustment by gamma-match.
