yes

might improve Wi-Fi reception, but it depends on the SuperBox model. Most SuperBox devices already have built-in Wi-Fi, and they usually don’t officially support external USB Wi-Fi adapters unless the system can recognize the adapter’s chipset. The Cudy AC1300 uses a Realtek RTL8812BU chipset, which some Android-based boxes might not support without extra drivers. So unless the SuperBox specifically supports external Wi-Fi adapters, it probably won’t recognize it.
