I'm building a yagi antenna for 800 band. The yagi calculator I used recommended making the radiating element a folded dipole, connected to the coax with a 4:1 coax balun. It also said that it was possible to use a regular dipole connected with a 1:1 balun. This makes sense as a folded dipole has about a 300 ohm impedance and a regular dipole has a 75 ohm impedance. I'm wondering if the other elements change the impedance of the antenna.
If I have a yagi with a folded dipole as the radiator, is it going to have a 300 ohm impedance?
Also, am I going to see any difference between an insulated and non insulated boom?
