Technical description MC20-C4-5
The Maxicore-20-4C-1 balun is a current balun with a transmission ratio of 4:1. By using two toroidal cores, the Maxicore balun achieves a particularly high power handling of up to 5 kW (CW, SSB). The usable frequency range is from 1.8 to 54 MHz.
The output impedance of the two-wire line is approx. 200 Ohm, the input impedance is 50 Ohm, PL socket connection. The balun is housed in a weatherproof casing with several ventilation holes on the underside to drain off unavoidable condensation. The housing is equipped with fixing lugs.
Application description MC20-C4-5
With a transmission ratio of 4:1 and its screw terminals for two-wire line, the Maxicore-20-4C-1 balun is particularly suitable for dipole antennas with balanced feed. These are normal dipoles such as a G5RV, but also resonant foldied dipoles with feed via two-wire line, fan dipoles. Other applications are loop and long wire antennae, Yagis with 200 Ohm feedpoint impedance and other designs.
The double toroidal core offers a very high load capacity due to its large cross-section, because this prevents the core from going into saturation. The maximum permissible transmitting power is 5 kW in SSB or telegraphy.
