I have as assignment to make a half wave dipole antenna, that radiates at 433 MHz. I am trying to figure out how to use a coaxial cable as transmission line. I know that the coaxial cable is unbalanced and an ideal half wave dipole is balanced. To properly connect these two is a balun required.
The main question I have about the coaxial cable is how do I connect the coaxial cable to the dipole when only the inner conductor transfers the signal? What is the best way to connect it together, taking in consideration that I also need a 180 degrees shifted signal connected to one of the arms of the dipole?
