At amateur operating frequencies, the FTDX10 is designed for 50 Ohm resistive impedance. Choose the appropriate antenna (dipole antenna, YAGI antenna, cubical quad antenna, etc.) for the operation and bands.
What is Impedance?
Impedance is the sum of resistance and reactance. It was defined as anything that can obstructs the flow of electrons within the electrical circuit. As a result, it influences current generation in the electrical circuit. It could be found in all the possible circuit components and across all possible electrical circuits. Impedance is represented mathematically by the letter Z and has the unit ohm. It's a mix of resistance and reactance.
