DMP has redesigned the tried-and-true 1100DH Wireless Receiver with your needs in mind. Now half its former size and just as powerful as it's always been! This high-power wireless receiver provides additional transmit and receive amplification for improved performance at greater distance or harsh building environments. Like the 1100D model, the 1100DH is reconfigured with an internal antenna. This new smaller footprint allows additional flexibility for placement in many applications.
