Does this improve Cable hd channels

HD is digital. Digital either works or it doesn't. It is not like analog signals where you can have varying levels of performance. If the HD picture is not breaking up then this signal booster should not give you an improved picture.

I was able to plug my cable directly into the back of the TV (no converter box was involved) and tune in the channels from the TV. I was able to get all the basic cable channels but not the HD channels.

No one else seemed to address the real reason this may work on channels 2-5. Most HD stations are broadcasting at different (ie higher) digital channel and your TV translates it to the correct 'virtual' channel. For example, in Greenville, SC channel 4 (4.1) broadcasts on digital channel 35 but you see it on your TV as 4.1.

I don't know...I bought this for my father who is in a nursing home and has vision problems. He has a HD antenna - not cable. Sorry I wasn't more help.

You will see the best the LNA40550 has to offer if you upgrade your cable box to HD.It's the difference between looking thru frosted glass

It has a digital tuner, so you can hook this directly to an antenna and pick up local over the air HD channels

If your cable signal is digital (most likely), it should help eliminate digital blocks that occur if your signal is marginal. If the digital signal cuts out completely, there may not be enough signal there for the booster to send to your set-top box. (If your signal is still analog, it should definitely improve it.) The booster needs to be installed at the service point where the cable comes into the house so it can boost signals for all televisions. You'll need the Motorola Power Inserter BDP-100/PI Remote Power Inserter to send power to the booster if the service point is outside or not near an electrical outlet, and it isn't included with the booster.

No. it only boosts broadband signal. Which would be internet and cable signal from a coaxial cable.

It will improve streaming only if you have a weak signal to the location where you are watching. If you have a strong signal already, it won't help. This device improves signal strength at remote locations. It will not improve speed if you have a strong signal.

HD receiver and HD subscription from Directv, does work. The real problem with most systems is the antenna is not able to be connected to a strong signal. Amplifires may help, but is only a poor substitute for a good signal.

This antenna picks up local HD signals in your area. I found that the signals I pick up is actually better than what I get with my current cable service. If you have an HD TV (digital ready TV) you will only need to connect the antenna to the back of your TV and then go into your TV settings to allow your TV to set the channels. You can go to AntennaWeb.com to find your local stations and those near you and their distance so you can see if you will get decent reception. Just remember, this is an antenna and will not let you pick up HBO, Showtime, and/or other cable only channels. Only your locally broadcast channels are available. Hope this helps.

This helped to improve analog signals. The current car and home tv run on digital signal. You will have to purchase a dtv antannae to get what you desire I believe.

I have an over the air antenna and a cable attached to it. So Yes it receives the over the air HD antenna signals in 1080i. I have had just the antenna split into both inputs and also the cable split into both inputs so you don't need 2 antennas. I liked it better with 2 antennas because in your area half your channels could come from the west and the other from the N. so with 2 antennas you could get them all and then you media Center software will do the rest automatically switching tuners for the channel you requested. I brought this up because the newer smaller silicon dust tuner called the "dual" only does one input and splits it internally. They also have a few more boxes that have other limitations you may be confusing this one with them. My main experience is with a windows 7 machine hooked to it. but I have had a Ubuntu laptop on the network and it could see the channel feeds too, so I assume it is the hardware decoding it and not the software.

No. It picks up only local channels in your area. Has a "search" that will auto select any / all in your area. But no, no proper cable channels.

Yes it does support HD, but you need an antenna specially made for HD. Also supports non-HD channels. Picture may not be as great though because HD comes in clear and regular non-HD channels come in fuzzy, which is normal, unless there's great reception. Where I'm at, I have 7 over the air non-HD channels. Once I have an HD antenna, I end up with 20 something channels including non-HD and HD channels.

No. Keep in mind, however, that amplification really only helps significantly if you have a long run of coaxial cable. (The antenna comes with 15' of coax, and I do not believe amplification will help you much over that length.) If you run a longer cable, then it would likely help. Basically, the signal will only be as good as what it is right at the antenna. It's all about signal to noise ratio (SNR). For purposes of explanation, consider the situation where you have the antenna right next to your TV, with a coax cable say less than a foot long. If you have an amplifier right at the antenna, all it can do is amplify the signal and noise (which is everything OTHER THAN the TV signal you want your TV to receive). If the signal is weak and insufficient from the antenna, the amplifier CANNOT improve it. What an amplifier CAN do is to strengthen the signal and noise ahead of a long length of coax leading to your set (if you needed a long length). That will improve things at the set end of that long length of coaxial cable. (The signal degrades and noise is added over the long length of cable, BUT, you improved things, i.e., the SNR, ahead of that length, so the result at the TV end of the long cable will be an improved SNR). BUT, keep in mind that if the signal was inadequate at the antenna, it will still be inadequate at the TV end of a long cable, DESPITE the amplification. Hope this helps.
