Question: How long is the antenna cord?
Document: I purchased this as a gift. It was fantastic, at first. Within three weeks, the screen was showing the picture very fuzzy with lines thru it. I was disappointed to find this out, long after the fact, since now it's past the return time. What a waste! !
(anyways this product is probably out of stock)The major issue I've had after only a couple of months or even after one month with this product is an issue with the power connector. For some reason, there is an issue with connectivity and unless I have the cord right at the connection point putting pressure on it in a downward fashion, it will not connect and power/charge. Until I started having this problem it worked as expected simply by plugging in the power cord to the connector.
Received my 9" Portable TV+DVD player, very fast and prompt service. The product is good, very convenient, the resolution is OK. I love the TV Output function, now I can hook up with my old television and watch digital channelsVery useful when it comes to long road trip!! A best addition to you car's entertainment! !
We have this item about about 6 months now. It works perfectly. The only slight setback is that the speaker is not very loud but it is fine especially for a 3 year old. I dont have to worry about it being too loud. Works brilliantly with headphones too. It has a long battery life. I have taken it on road trips and fishing trips. The other night we had a power failure and we decided to see if we could get some tv channels.
This product was just what I was looking for, convenient for anywhere and the price matches its quality. I used to try to read a book as I tanned before going out for a surf but I would just fall asleep, now I bring the 9 inch to watch movies and it's great. When I go on a long drive with heavy traffic, the kids can watch their shows/movies on the 9 inch and not get fussy.
Thechannel scan does not take long. I scanned near a window totry and get the most channels and also attached the magnetbase to something metal; it does help.2. DVD/CD: I tested a commercial video and one I copied to aDVD-RW and both worked without any problem and looked good onthe screen. I did not hear any noise coming from the spinningspindle. It was quiet.3.
I purchased the player/tv for christmas. It was a really cool gift. The problem started few weeks later when the DVD player started to freeze up during the middle of a movie, now I have to see how to get it repaired which it looks like it is going to be a long process of getting different numbers and I don't know what will involve. The quality of the workmanship is not there the DVD cover does not close correctly and some of the speaker cover keeps coming unglued.
When I started shopping around the portable TV, DVD, I found this product, it's cheaper than Brand name like Sony but comes with more features like Digital turner and usb port and SD card reader, and it's a 9" widescreen LCD which looks 50% larger than old 7".It's a real good product. Plays long (2.5 hours). Color adjustings great. Love the little remote it came with.
Love this player. Features mentioned are great. Can watch DVDs from flash drive, SD card, or DVD. I love converting my videos to the DiVx format and putting 8 on 1 DVD. Great for long car trips. Can't get any TV channels where I live (80 miles from nearnest TV station. Plan to use it when I am in metro areas, especially for weather an sports on the go. Way more formats than mentioned on here for videos. So far so good.
Maybe a Larger Antenna would be Better, I have not tried this yet. Hope this helps decide..
Answer: I would estimate about 5-6 feet.  My mother can rest the TV on the bathroom counter and put the antenna out the window.  Hope this helps.
