How to model coax feed for dipole in FEKO?

Hello everyone,

I'd like to model a coaxial feed for a dipole in FEKO. The dipole is part of a Yagi antenna with a metal boom, so using a wire source between dipole feed gaps (the dipole is modeled with cylinders) inside the metal boom is causing problems. I'd imagine a coax feed would fix this.

How can I accomplish this?

Thank you!

Thank you for the reply. Looking on p. 262, they talk about using the A3 card. Is this the only way to do it in FEKO Suite 5.4? Isn't there a way to do it in CADFEKO, and model with physical coaxial dimensions like in HFSS?
