The Amazon diagram shows two bottom connectors. There is a pair of the same two connectors on the opposite side. Where do I connect the antenna and where do I connect my wound wire?
The moving vanes of the capacitor are connected to the metal frame.
The two visible solder tags are connected to the fixed vanes of the capacitor. The other two tags that you describe are probably also connected to the fixed vanes. You can confirm this by measuring the resistance between the 4 tags. I expect the resistance reading to be almost zero ohms. Without you showing us the schematic we can't tell you where to connect it.
