We had a lady call us saying that she had no TV Reception in her house she had just moved into. When we arrived there we noticed that there was no power supply for the TV Antennas masthead amp. Do we ventured out to the van to get a power supply for a Hills masthead amplifier. When we installed it & turned on the TV & retuned the TV and all the channels came up the lady said, oh thank god now the kids will leave me alone. Another VERY happy customer for TURNER's hD/AV.
