The Dwyer WTDL-RX Wireless Transceiver, USB Cable, Software CD and Manual, and A/C Adapter for the WTDL Series is designed with a high powered transceiver that has a substantially long transmission range, meaning better performance in occluded environments (ovens, refrigerators, etc.). The WTDL-RX also includes an external antenna, allowing more flexibility with mounting positions in both orientation and proximity to metal walls. This may be used as a repeater, or directly plugged into the PC.
