In my experience there are a number of things that can affect signal quality.
1. Cable size or gauge - using too small of gauge, especially on runs of more than 50 feet can begin to degrade signal quality.
RG-59 is a poor choice and is acceptable only for short runs in good environments and is susceptible to interference. It is no longer used for cable for these reasons.
Do not use RG-58 as it is for 50 ohm impedance applications instead of 75 ohm impedance of which cable is one application.
A RG-6/U size is preferable and RG-6/UQ is best as it has double the shielding than the regular RG-6/U.

This is a very good discussion on the various cable sizes and signal quality.
2. Adding splitters will split the cable, but remember that you are also splitting the signal as well so each signal line will be reduced by the amount listed on the splitter (i.e. 7db).
3. Union fittings can cause signal degradation because they are an opening for interference and they can corrode causing an increase in impedance.
4. All connections in general should be tightened with a small wrench and covered with some type of insulating material to reduce weathering and corrosion. I use shrink tubing when I need to have a connection and there is a possibility of corrosion.

What is better about digital TV reception in comparison to regular cable reception?
Digital TV receivers offer high definition broadcasting and a clear combination of audio and video. Digital TV receivers attach directly to your TV with a cable and do not require any additional hardware.
Will plugging an optical audio cable directly into the stereo amplifier offer better sound quality than plugging it in from the television or not?
The optical cable would be the best choice.
What is the Difference between HDTV and regular tv?
The difference between digital cable TV and regular cable TV is the quality of the video stream that is being presented on the TV screen. A digital cable will provide a better quality picture, usually with a larger framerate and bitrate and as such these will look better on a larger TV.
How does the picture quality compare on digital satellite as opposed to basic cable?
There may not be that much of a difference, depending on the TV on which you are viewing the satellite or cable. Based on where you live, reception of either the cable or the satellite might be better, but that's a reception issue, not a picture quality problem.
Which is better 1.3 hdmi cable or 1.4 hdmi cable?
There is no difference in the picture quality. You simply need to purchase the cable for the application that you have. If you have a normal Blu-Ray, HDTV and Cable or Satellite HD receiver, a HDMI 1.3 cable is the right type. For 3D televisions, purchase a 1.4 cable.
What is better direct tv dish or Time Warner cable?
Satellite TV is almost always better than cable.
Does cable television offer the best quality?
Cable television is said to offer the most reliable quality, though not necessarily the best. Some people swear by satellite TV for excellent reception!
If you have an HD tv does the ps3 come with everythiong to make the game be in HD?
No. Currently the PS3 only ships with an RGB cable, basically a scart. This only gives standard def quality. You will need to buy a separate component or HDMI cable (HDMI is better) Everything else is built into the console.
Does a bi-directional cable splitter improve signal quality to a tv?
Cable splitters, joiners, adapters and similar products will never improve signal quality.
How do you change to 1080p on a toshiba 46sl412u?
The Toshiba 46sI412u is already a 1080p LED TV. If you are using this TV with a cable box, you need to do fix the picture quality on the cable box. Some cable boxes will automatically detect the picture quality.
How digital cable TV works?
A signal is sent through the cable at a much higher frequency than regular cable. Additional data is sent in this signal to support the original audio and video signals to ensure that they are received in much better quality than analog signals. This additional data and the type of signal sent is what allows the quality to be so much better than older analog signals.
How effective is a cable TV signal booster in terms of picture quality?
TV signal boosters will significantly improve the picture quality of your TV if the poor quality you are currently experiencing is due to signal degradation. If the cable signal is poor from the source, a signal booster will not help.
