Don’t hesitate to call these guys.  No return call from one business I contacted.  Made an appointment with another who was a no call/ no show. Finally reached a live person (Brian) set up an appointment and Gavin showed up right on time.  Sorted out our issue by replacing an old attic antenna and setting up a Roku.  Had the patience to show us how it operated.  Professional,  courteous and a fair price. Very pleased.
