Bluetooth Adapter for Desktop

This YOUHUA Bluetooth adapter adds wireless connectivity to a desktop computer through a USB interface. It is intended for users who need to pair peripherals such as keyboards, mice or headsets without built-in Bluetooth support. The compact form factor suits standard PC builds where internal expansion slots are not available.

Tri-band antenna extends coverage

The bundled 9 dBi omnidirectional antenna operates across 2.4 GHz, 5 GHz and 6 GHz bands with RP-SMA male connectors. It replaces a stock antenna on compatible routers, PCI-E cards or USB adapters to increase signal reach in larger rooms. The tri-band design allows the adapter to maintain a link on the least congested frequency.

Limited to RP-SMA devices

The antenna only fits hardware that exposes an RP-SMA female port, so it cannot be used with sealed laptops or devices lacking external antenna jacks. WiFi 6E operation requires a supporting router and client device; older 802.11 b/g/n/ac equipment will connect but not use the 6 GHz band. No driver disc is included, so the host OS must supply compatible drivers.

Questions about this item

Will the RP-SMA antenna connector need periodic tightening or replacement?

The RP-SMA male connector is a standard threaded interface; it does not require scheduled tightening or replacement under normal desktop use.

Which frequency band hits its range limit first when the adapter runs continuously?

The 6 GHz band (5900-7125 MHz) has the shortest wavelength, so its effective range drops off before the 2.4 GHz or 5 GHz bands during sustained operation.

How much heat does the adapter produce when it stays powered all day?

As a passive antenna with no active electronics, it generates no measurable heat during continuous use.
