It seems that most anode bandswitching arrangements put the switch wiper more towards the output side of the pi or pi-L network (e.g., on a pi-net the switch wiper is on the load side of the inductor).
Is there a particular reason for doing so? It would be a lot easier to add padding capacitors for the low bands on a single-pole/wafer switch if the wiper were on the tune side. Or does the wiper assembly really add that much stray C?
