,,,41,6mm...!!!
(48,7+34,5)/2 = 41,6mm-1,5mm=40,1

I don't know, I have to study...!!!

And how do you want to do this?

I think this one...

,,,yes dear tcl32...!!!

I wrote to you above that the antenna has a 240-300 ohm impedance, so you need to adapt for a 75 ohm cable.
,,,something like that...
-
The impedance is highly dependent on the construction details. In general, you can expect 100-400 ohms of impedance. The nominal impedance is generally considered to be 400 ohms.

No, the drawing is very good...!!!!
I'm going to make a simulation on this antenna.
