GAF-860 is a low power DVB-T / DVB-H gapfiller designed for implementation of wireless digital-TV network for any sort of buildings and residences. Wireless digital-TV network is realized easily with GAF-860 by connecting it with ordinary roof-top receiving TV-antenna and a small sized transmitting antenna typically located in a staircase of the building, thus making the reception of DVB-T programs possible in all positions of the building with simple indoor antenna.
