You will need to connect to a satellite or cable provider that will give you a signal box and remote to pick up digital signals and your favorite tv stations. Everything is turning digital.

Is Clear-Cast TV micro antenna for free TV access a legitimate thing?


The advent of HD TV has allowed for a new round of hucksterism to occur in the TV antenna industry. The televison channel spectrum is the same as it always was but the signal modulation scheme employed now is "digital", which is for the better. Signal propagation is the same as it was and it is not necessary to buy a "digital" TV antenna unless you fidn it necessary to receive TV channels that have sprung up from new directions. VHF and UHF TV signals travel in straight lines and are the strongest when your receving antenna is "aimed" at the transmitter for that channel. Since transmitters are lcoarted all over the poalce, you can eoither use a mechanical antrenna rotator to position the antenna to aim the transmitter of choi ce or use multiple antennas aimed in various directions.

Genrally speaking, the "cheaper" antennas have fewer elements and are thereby less critical to aim. They have a broader beamwidth, so-to-speak, provideing less "gain" in a specific direction in favor or a larger average gain over a broader "angular displacement.

Digital TV signals are not prone to "ghosting" so an array of cheap antennas aimed in several directions will suffice to capture the digital TV signals in your local area. Amplifed antennas are poor substitutes for "real" (passive) antennas placed in attics or as high as possible outside. TV signals are blocked or absorbed by buildings, trees, and such and the signal intensity can vary with the weather and even when leaves are on the trees and when they are not. All your digital TV requires is enough signal in order to work. A small amplified antenna sitting atop your TV may work fine though the signasl is barely above the minimum threshold. When the weather grow wetter, that singal may be beleow threshold and you won't get that particular channel until there is less moisture in the air!
The same is ture, of course, for an antenna placed high up on the roof, but the odds are far better that it will work so much better than the tiny amplified antenna on the top of the television simply becaeu the TV suingal inside the house, at lower elevation, will be inherently weaker to begin with.

Hope this helps you decide.

No singal antenna on delphi sa10175


Could be the antenna, the dock, or the radio itself. If you have another kit or boombox, I would try swapping antennas out and so forth to narrow down which part is causing the issue. www.tss-radio.com has replacement parts.

Check input type, if using antenna, there may be 2, ATSC and RF (not used anymore) if using box, make sure you are on correct input (hdmi, DVI, RGB, AUX, etc)

Pioneer inno will not recive xm singal


Are you still having this problem? Sounds like you just aren't getting a good signal. Antenna is not properly mounted, not getting good singal.
Or, the antenna and/or cable is damaged.

How do I boost a digital TV signal?


No don't buy an LCD TV! I mean, unless you want to, they are nice :-) But you'll still have the same antenna issue. I looked up your antenna, if it's actually working just fading in and out, try an in line amplifier first (radioshack 1501170), and if that doesn't fix your issue, time to upgrade your antenna. It does get a little pricier, but do keep in mind the whole set up is good for 10-20 years. Before going back to RadioShack, go to this website:
www.antennaweb.org

If you live closer than 15 miles, rabbit ears
If you live closer than 20 miles, omnidirectional
If you live closer than 50 miles, midrange outdoor (oldschool arial w/ rotator)
Further than 80 miles, you'll need a long range with rotator, perhaps even an amplifier to go with it. Print off what your results were on antenna web and bring it to a RadioShack or a local antenna store and they should be able to point you to the right antenna for your particular location.

is the antenna a UHF/ VHF type? most of the broadcasters are broadcasting in UHF for the digital, also an antenna pre amp will help tune in those distant stations. you must point the antenna in the area of the signal. if you are able to pick up 35% of the singal or better, you will have a picture.
