Just to try and be clear on the important issue you raise here. When I posted this model in post #537, I suggested this very point. See my post below where I said:
So, I think this means exactly the point you're making here Bob, a 2 wire insertion object at the end of a wire, is not and will not work in making a model that is close to correct.
I use to make this very mistake as noted in the model you referenced, and it was wrong them, but I did not understand it at the time.
This model, as it is, is just a work in progress, and it has flaws. The coil is just a coil, and it only adds inductance as you noted. Now I need to use the Transmission Line tool and make the coil simulate coax with 2 wires, and the bottom wire of the GM is also coax with 2 wires. Just haven't got to the point of doing that yet.
But I'm still not sure either, that I can get the model to act like a GM, and for sure that might not happen unless I can also include the stub and the capacitor in the model.
I think if I can get the choke to work like a choke and place the feed point at the bottom of the coil, like the real GM, and the Average Gain is = 1, I might not have to deal with figuring out the match.
I'm still working on this model. I probably will also have to add a mast in order to have something to make the connection for the 2 wire insertion object...the feed point.
I wish I had checked my blown GM out a bit closer to see how all this was put together at the coil end. Got any suggestions?
