Question: Will this pick up channels like 5.1, 7.2, etc?
Document: While most HDTV channels are UHF, I happen to live in a market with 4 UHF and 4 VHF signals. The VHF channels can be tough to receive, and many so called "HDTV" antennas don't pick them up at all. But this hdtvi has 2 long rabbit ears for VHF. I use mine extended about 1/2 way (it depends on the target frequency you are aiming for--mine is Ch 9) and can pick up 7 of the 8 signals within 5 miles. The 8th station is 20 miles away and the hdtvi will pick it up from the attic when pointed directly at the VHF station.
Everything else is UHF (including the ones your TV calls decimal numbers like 5.1, 5.2, etc) which uses the loop antenna or t-cross type elements as in this model.One more note, an "amplified antenna" will not improve reception. They are made for applications with long cable runs or where you need to split the signal to several locations--they boost the signal to overcome signal loss introduced by the cables and splitter. If you are connecting the antenna to a single device, then the amplifier will not help you, in fact it's more likely to make things worse.
We live about 10-12 miles from all the station towers and we pick up perfectly clear signal on 26 channels with this antenna. We don't even have to extend the rabbit ears to get a great picture on the VHF channels which made my wife and I happy. The cost is perfect and we couldn't be happier with it! We have it positioned on top of our entertainment center, about 6 1/2-7 feet off the ground next to an outside wall.
I had bought a 7" portable TV in case of emergencies and such because I live on the gulf coast, and with the included antenna, I wasn't getting the Hi VHF channels, which are the news/weather channels in my area. The Terk HDTVi did the trick, and I can get pretty much all the local channels in a rural area with a little adjusting. The cable is a little short, but you can pick up a 5 or 6 foot coaxial cable and a female to female coaxial coupler cheaply.
This product does the job, but you might not get all the HD channels I only got maybe over 5-7 stations. which is not so bad but I hoped to get quite a few more. I would have given this product a 5 but since I don't get quite as many channels like I would have hoped is way it gets a 4 star.
- installed in 10 secs, all channels were there and then some. CBS needed some tweaking of antenna position, but the other channels popped right in. So I can put up with some moving around of the antenna for 1 channel - or I need to play around some more to get ONE position for all channels.Get this antenna. I'm 12-15 miles from the towers, 2-story aluminum sided house with nothing but trees and an airport (3-5 miles away) inbetween. The antenna is in a closet on the other side of the wall that my TV is mounted to.
This is my 4th antenna. (amplified, not amplified, with rabbit ears and UHF only directionals) I did a direct swap with my Phillips Silver Sensor which didn't pick up the 2 channels in the VHF realm (RF CH 10 and 13,,,not their corresponding "virtual" digital channel TV designations of  # 9.1 and 12.1)(CW and Fox in my case) and all channels were of a higher signal strength and less varying without any adjustments yet. This is the one for me if it passes the prime time test.
I guess it depends what you want to do with it, but I had to give this product only 1 star for deceptive advertising.This product is for you if you live less than 10 miles away from the stations.This product is not for you if you live the 45+ miles away that the product claims.This didn't work at all for digital or analog 39 miles out at my house in 60042 Island Lake, IL. I have the indoor antenna pointed southeast at a sliding glass door on the first floor trying to get the Chicago stations.I brought this to my uncle's house in Oak Park 8 miles out and gave it to him instead of paying to return it and got all the channels and channels I'd never heard of before like CH 24  some Asian channel, CH 48 UToo, and CH 62 some Jesus channel.This picked up the elusive CBS 2 Chicago (RF 12) in Oak Park, but not out in McHenry County.Disclaimer: I actually got the amplified version, and I just posted this review here too to warn buyers that the advertising is lieing to you.
I was weary about this antenna, from the negative reviews, but I tried it anyway (always have 30 days to return it), and I couldn't be happier. I was worried because I live 20 miles out of town (Maricopa, AZ), but I pick up every local station in Phoenix. I wasn't getting good signals on VHF (2-12), but every station had a UHF alternative. For example, I'm getting channel 5 on 17, and 12 on 36 (but they're 5 & 12 on my DTV box).
I have tried many different antennas from Walmart, Target, etc and this one was the easiest to connect and was able to pick up 80% more channels than the others for the same price. I have recommended this one to many people already.
Answer: Yes, it should if they are strong enough, those are just other RF (Radio Frequency) signals.
