Dimensions & Mounting Information
Product dimensions: 271 W x 200 H x 73 D mm. The receiver must be surface mounted internally, ideally on a flat horizontal surface in the building’s roofspace overlooking the area requiring RF coverage. Avoid locating too close to large metallic objects (such as a metal clad roof) and thick structutal walls. If this is unavoidable, consider using the QT422RXEX external extension aerial instead of the mini-aerial supplied.
