Interesting. Why is this? It seems like it could make for a rather
crowded tube compartment. The loss of any coax at HF seems minimal, and
all that having a transmission line in there would do would be to rotate
you on the Smith Chart back toward the source a slight amount before you
apply your matching networks. So why does it make a difference in
efficiency? What am I missing?
