If your TV has a digital tuner, you can get any HD channels if you use the correct antenna pointed at the transmitter and are close enough to the transmitters. (Antennas labeled as HD are not always appropriate for your location.) Your TV will downgrade the signal to 480i if the TV can't support a 720p or 1080i resolution.
First where do you live? Use antennaweb.org or tvfool.com to determine the correct placement of your antenna for your area/stations. AntennaWeb uses a very conservative signal strength calculation despite assuming an external antenna. Tvfool will give the antenna color rating which is also provided on the antenna package. When properly installed (with no trees or hills blocking the signal), the matching antenna should receive the listed channel.
If you use a splitter to share the signal with several TVs, you may need an amplifier to bring the signal strength to that needed for the tuner to interpret the digital signal. (Note: amplifiers and splitters can fail and the amplifier may become a signal filter blocking the signal; test the antenna strength on a direct connection if there is a problem.)
If you do not have a digital tuner in the TV, you may have gotten an SD digital to analog converter. These are the more common (and available with the government coupon) converters. You will need to get an HD capable tuner to see the full HD signal.
Please add a comment with your TV model and antenna choice for additional support.

(antennaweb indicates that my external antenna should only get the stations 10 miles away. We actually receive the channels from 30 miles away. We use an amplifier splitter to feed the signal to several TVs. I set up two indoor antennas for a neighbor's TVs. One gets the signals from the transmitters 30 miles away and the other from the transmitter 10 miles away. Both get HD from the stations with HD broadcast (not all channels are in HD here). The difference is totally due to antenna placement.)
I have a Hitachi 42HDT52 and cannot get ANY channels with a RCA Indoor Flat Antennae with Amplifier. I hooked it to the Air terminal on the back of the television, tuned the Input to air, and then went into Channel Manager and set it to Autotune to Air. Got no channels at all! Checked to make sure the range was far enough and it should be. Can anyone help?
1) Try the antenna on a different TV or a different antenna on the 42HDT52. I've seen some amplified antennas fail out of the box. Indoor antennas are really sensitive to location relative to walls and other items blocking the signal. So try moving things around. (Tall trees and buildings between you and the transmitters may cause signal loss.) 2) The specs for the 42HDT52 do not list an ATSC tuner in the manual I have. Hitachi may have sold some of the TVs in this line as HD-ready sets. To check if this case, try using an OTA digital-to-analog converter with your antenna and TV. Note: most OTA converters only have SD signal output.
I hope one of these suggestions helps. Cindy Wells (ATSC = digital tuner in the U.S., NTSC is the analog tuner)
I have a similar problem I have a sensory model hdl19wb series a and I'm using an antenna and it is a GE antenna model 14068 it's an indoor antenna and it keeps saying that my digital strength is low how do I rectify that or do I need to change settings
Unfortunately, you probably need a better antenna set up as high as possible outside. You can try using a powered antenna amplifier,https://www.amazon.com/antenna-amplifier... . However, the signal strength improvement will be limited since your building walls absorb a large amount of the OTA signal. Cindy Wells

SOURCE: Get HD Signals but it Says Channels not available
Try checking to see whether your input is set correctly. If you have composite cables connecting your cable box and television, make sure the input is either Comp1 or Comp2. Same thing if you're using HDMI.

The problem could be your antenna. Many people will buy small indoor tv antennas and wonder why they're not getting the signal that they want or the channels that they expect. Its not your fault. Digital signal is in two formats: UHF AND VHF. Some antennas only receive UHF. But many of the low band channels are VHF, so 1) you need an antenna that will receive those signals and 2) you need to know how and where to install that antenna and 3) you need to know if you need a signal amplifier depending on your coaxial cable length and number of connections. I recommend visiting dennys antenna service (no I don't work there and I have never purchased anything from that website. He just has an excellent informational article with a great deal of "how to" on his pages.). http://www.dennysantennaservice.com/2029710.html This should be of great help to you. Happy viewing =)
SOURCE: do not get but 7 channels
HD would include a search in a digital mode.Also, there may be another RF connection marked HD or Digital connection, use that RF connector. Thanks for asking me.
