Hello!
I'm having problems simulating a TDR high voltage pulse generator in LTSpice. The high voltage generator works fine I guess, the pulse generator does not work. I don't understand how it even works so a explanation would be appreciated. I found this circuit in this YouTube video and i will add the link at the end as well as my LTSpice circuit. Anyway if someone finds my mistake or has any advice I would appreciate it.

Oscillator and high voltage generator that will be connected to the pulse generator and coax to the left.

Pulse generator and coax (RG58).
