Hearth Products Controls Bluetooth Wireless Remote Control for High/Low Models

Hi there, The Hearth Products Controls Bluetooth Wireless Remote Control for High/Low Models itself does not come with a separate antenna, as it has built-in Bluetooth capabilities. An external antenna, such as the HPC Fire Bluetooth Antenna for EI Systems (model 312-ANTENNA), is available as an optional accessory for improved reception in environments with potential signal interference.
