Yes, that's it.
This is a U2V2, and you can also buy an additional U3 DLC for an extra 30 yuan to attach it at the front, turning it into a dual-segment Yagi antenna (U5V2).
There's also a version that allows you to pack the entire oscillator into the PCV tube, creating a portable travel oscillator with the same price.
If you need something, just ask RSJ directly.
