Question: Do I also need an antenna with this tuner?
Document: This part is identical to theAvertv Hybrid Volar Max. For the thirty dollar difference, this item does NOT include:* A small antenna. * The Avermedia PVR software. * The proprietary composite input cable.If you have Windows Media Center or something like MythTV, then you don't need the Avermedia PVR software. You also don't need the H.264 encoder because like Handbrake.fr is better.I have two of these USB tuners in my home theater. No drivers are required for Windows 7 Media Center.
I use Windows 7 and this TV Tuner was very easy to install and it works very well. I use it to record over-the-air TV signals, Two thing to keep in mind here: 1) During the setup for Windows Media Center, you need to have an active internet connection. Your computer will need this for the latest TV setup data for your region. It will also install a program called Play Ready. 2)  You will need an adequate TV signal for this tuner to work properly.
After reading other reviews that claimed that this tuner had good sensitivity, I decided to buy one and try it out. They lied. Its total junk and hardly picks up anything over the air other than exceptionally strong signals. I was using an outdoor OTA antenna that works fine with my TV and with my DVICO tuner.To date, this is the least sensitive tuner that I have tested. If you need a good ATSC tuner, don't buy this one.
I have tried this unit on my windows 7 laptop and my windows 7 desktop. The tuner was found with no problems in either verison of windows MCE. I have comcast on the desktop and it found all the free HD programing. On the laptop it found all the over the air stations that the antenna could get, but that is limited as the antenna that comes with the unit is not the best. You will need a much better antenna if you want to pull in the weaker local stations.
I use this tuner on my PC to enable me to watch TV while I do Email or surf the web. I have it connected to an outside antenna so I get good over the air digital TV. This tuner uses your Windows Media Center so you need no other software. I'm using Windows 7 Home Premium. I'm not sure if the older operating systems have a media center like windows 7. You probably should check this out first.
Works great with very nice picture. It's better within major cities. Also it is not really a kit as it only contains the tuner itself. Instructions are a given and the 3 inch usb cord is basically a necessity too. I was hoping for a basic antenna or at least its input adapter for a game console or something..
The tuner worked great for a month, then all of a sudden it died. I thought it was my antenna atfirst not receiving TV signal, but tested it with the tuner on my TV and all the channels was available.Also the driver and Avertv media center software are very old. Looks like the last release was codedin 2009.
It is designed to be easy to set up, and it is, if you have Windows-7 Premium. It gets okay quality from my cable line. I have not tried it with an antenna yet but the coaxial jack gets hot with use. It is also an FM radio tuner which is pretty cool. HOWEVER, it does not come with an antenna, so make sure you get an antenna if you plan on using this for that purpose.
Not a TV watcher at all but good to have a way to watch TV with my laptop (running windows 7). Plug and Play recognized the tuner but I also downloaded the latest driver from the Avertv site. I attached an external HDTV antenna and picking up over 30+ channels. As long as my laptop has a good battery charge I can watch TV for news and information even when the power may be out due to a storm.
I purchased my AverMedia MTVHVMXSK in September of 2010, and have been using it 24 hours a day on my Acer Revo HTPC with Window Media Center. Its hooked to the digital cable line right now. It also works like a champ with the antenna in the attic. No problems setting it up. I've got the tuner stuck back behind the entertainment center out of sight (not really good air flow). So far only good things to say about it.
Answer: Yes.  Need to attach antenna's coax cable to device.
