Hi LHL12,
It really depends where you live. If you live in an area where the stations broadcast in both UHF and VHF, then you'd need an antenna that does both. If only UHF, which is the case for most cities, then you need only a UHF antenna. If you want to pick up the analog VHF also, then yes get the VHF/UHF antenna.
BTW, if your satellite local feed is out, you can always switch to your antenna. Besides, for viewing local HD broadcasts, you'd want to use your antenna.
Here's a link to find out if and when your stations transmit in VHF or UHF or both; where to point the antenna; recommended antenna; hd programs, etc.
