I agree with GUM , you have Way Too Many Easy To Receive Digital Tv Stations. The digital transmissions are very strong. If the house is not wrapped with any type or kind metal such as but not limited to metal siding or stucko with stucko Wire. And if the house does not have a metal roof. And if the insulation in the house is not metal foil backed. And if the walls are not made out of poured concrete. I know it's a long list , but most people do not understand that metal blocks and reflects Tv signals. And that poured concrete walls block Tv signals. Any way the Tv signals are very strong so , indoor Tv antenna will receive many channels.
