LIJIANI RD-239S Radio + W2 Signal Repeater: Unboxing Video

A brand new radio antenna reception method: the RD-239S main unit and the W2 signal repeater are a perfect combination. Place the repeater outside the window; it receives the radio signal, decodes it, and then transmits it back to the main unit via a 2.4GHz channel, much like Wi-Fi. This signal can penetrate walls and is unaffected by electromagnetic interference from household appliances and lights. Unfortunately, our tests showed it can only penetrate one wall. The main unit receives the repeater's signal and can control it for station selection. If the repeater is turned off, the main unit will activate its own antenna, reverting to a regular radio. When the main unit is receiving the repeater's signal, the motherboard's antenna system is off, making the main unit essentially a Bluetooth speaker. This is ideal for those who want to listen to the radio at home. Audiophiles might use two repeaters, one placed in front of the house and one in the back, as the signal only penetrates one wall; two would be even better. It supports FM/AM/SW/VHF/AIR/WB bands, and the W2 supports single sideband. It also supports Bluetooth, TF card playback, and a mobile app for radio control. Furthermore, it boasts excellent sound quality. 支
