- The folded dipole is horizontal between the reflector and director
- The impedance is 50 ohms, direct fed. (RF- choke or 1;1 balun)
- The element diameters are 18 mm.
- This antenna is designed with NEC4, NEC2 use will lead to inaccurate results.
- DO NOT CHANGE DIAMETER / LENGTHS. if you need other dimensions please feel free to ask.
