Make sure that the Tv is scanning for Broadcast Digital Tv Channels. Not any kind of broadcast analog Tv channels. NOT any kind of cable Tv channels. Aim the front of the UHF panel antenna at about 276 degree magnetic compass. The front of a UHF panel antenna is the flat side that has the V shaped metal reception elements. Look inside ALL of the connectors on the ends of the coax cables and see if foil shield and shield wires are pushed in toward the center conductor of the coax cable. See if the shield wires are wrapped around the center conductor , if they are then the signal will be shorted out , remove the shied wires from the center conductor. If the foil shield and shield wires are pushed in toward the center conductor then push the foil shied and shield wires away from the center conductor. You must remove wall plates and look at the connectors. Also one of the other trades might have put a nail or staple through the coax some where or cut the coax some where. The best to do is run a coax from the antenna direct to the Tv. I say that 99% percent of people working in any kind of department store now days do not care anything about anything and will tell you anything.
