Hey, Mr. Donald King, I understand it perfectly and easily. Then, maybe I can help you to comprehend it, too.
You simply have two options, when you want to connect the antenna to this circuit: you can connect it either to Jack1 or to Jack2, once the two connectors are leading to the same point.
As to the switch S1, it selects the RF transistor 2SC2570 when you want to amplify HF and VHF signals, and selects the FET RF transistor MFE201 when your aim is to boost UHF reception.
Any other doubt?
