You may not even need a VHF antenna.
Just because you're watching a channel that calls itself 2,4,5,7, or anything under 14 doesn't mean it actually broadcasts on VHF now. Those channel numbers are what was used prior to 2009 and today they're just placeholders really.
If there's a specific channel you're worried about, going to its website or wikipedia page will usually tell you what the actual broadcast channel is. Going to a site like TVfool.com will give you information from public records to tell you all the channels in your area. If you really want professional help, use our free antenna request service
Either way, it's worth knowing. UHF antennas are usually smaller than VHF ones and that also usually means they are less expensive. Don't take it for granted that you actually need VHF -- a lot of stations moved from VHF to UHF during the 2000s and never moved back.
