A set top or indoor antenna is very unlikely to provide good, consistent,
reception. An outdoor antenna is a must. Because you have low VHF for
PBS, Hi VHF for two major networks and UHF for the rest, you will need
an antenna designed to receive everything for your area. The channel
master 3018 model would serve you well.

Keep your RG6 cable run as short as possible to ONE tv at first. Keep
it simple, especially at first. Avoid trees as much as possible. Trees nearby ruin reception.....
