NEC-LIST: YAGI antenna with gamma match, what is the right way

Hi,
and thanks for taking the time to read this. I am just digging into
NEC-2 and have some questions how to do things right. I recently
calculated some 2m and 70cm Yagis feed with a folded dipole. I had the
results for the calculation so I could check if I did everything
right. No I want to calculate my 10m - 7ele Yagi. This Yagi is using
a Gamma match (in practical with two telescoping tubes and PTFE
isolation), and I am wondering what I must do in this case. I no the
Gamma match is acting like a C (maybe with Resistor and Coil in
Series?). What would be a good way? For those who want to help me I
included the File of what I have so far. Tried to use tapered elements
on this Yagi.... Hope that possibly simply question is not bothering
the group, but I am just starting....

Regards

Carsten, DL6LAU
