Will RG59 cable work for cable HD signal will 6 way splitter for normal cable work for HD cable?
Is cable coaxial the same as satellite coaxial?
Most times they are the same but a satellite signal needs to be carried by RG6 cable it is a heavier gauge wire then say RG59. Regular or analog cable signal is sometimes carried by RG59 but digital cable should use RG6. +++ The primary specification is not conductor size but the impedance and capacitance of the cable.

What is the maximum length of RG59 for signal to travel?
RG59 is a video standard co-axial cable and is normally sold as an economy cable. Losses on this type of cable tend to be higher than more expensive cable. A standard definition signal can be run in excess of 300 feet before losses are noticed but the signal quality relies not only on the cable but also the signal driver (the source) and the receiver (the display). If the source or receiver are not properly designed, there may be a tendency to show a ghost image appearing to the right of the original image. For analog high definition signals (extremely rare today) the maximum distance will be much lower, perhaps in the region of 40 to 50 feet. If the application will be supporting HD signals, RG59 is probably not the best choice. Invest a little more and look for cables that have lower losses - PSF1/3, for example, is more expensive but also more effective.

Can you use an audio cable for video?
For short signal runs, audio cable can be used for video without any issues. As the length of cable increases, it become more important to use cable that is designed for video signals. For most video signals, this will be a 75 ohm co-ax cable such as RG59. There will only be a noticeable difference in quality once the cable length exceeds 10 to 20 feet.
What is the difference between RG59 and RG6 cable?
RG6 and RG59 cables are both forms of co-axial cable that have a characteristic impedance of 75 ohms making them both useful for video and television applications. The RG designation is now an obsolete one because it failed to define a full standard for each cable. The standard covered the center conductor size, the outer conductor diameter and the overall diameter. It didn't cover performance related specifications. Despite the fact that the standard has been withdrawn, the designations still remain stubbornly in use and show no signs of becoming less popular. RG6 cables are larger diameter than RG59 and frequently is offered as exterior cable. Some versions of it have steel wire for strength in suspended applications while others have a copper inner core. There are versions that have multiple braids and foil screens, achieving up to 95% screening while other versions have lower screening capabilities, down to 50% in some cases. RG59 tends to be sold as an economy cable. Screening tends to be lighter than most RG6 cable although like RG6, RG59 is supplied in a wide range of qualities. RG59 has a higher signal loss for a given distance, largely due to the smaller diameter although once again, this characteristic varies from one model to another. In application, RG6 is often used for cable TV while RG59 tends to be used for shorter runs of baseband video. When selecting either, avoid the cheapest prices as they will normally be the lowest performance. Do look for multiple screening braid or foil screened for longer runs.

Is satellite TV cable the same as cable TV cable?
satellite cables and TV cables are the same to a point. the difference in the too are is the TV cable a RG59 or a RG6 RG59 will not work with satellite because if the smaller center conductor with satellite it pushes power were it will end up destroying the center conductor RG6 witch is in newer homes is ideal for both satellite and cable RG11 is used with TV cable from usual the box / tap outside to houses usually running over 300 ft depending on the DB coming from the starting location

Can you use a standered AV cable with yellow red and white to carry a component video signal through YPbPr?
Yes you can, but the cable isn't really right for video signals. Even the composite video signal that is normally carried by one of the three cables suffers over a long length. The best thing to do is to plug it in and try it. If vertical edges on the image appear slightly smeared, it may well be down to the cable and a new cable is called for. Have no worries - you won't damage anything by using the cable. The right cable to use, if you have a choice is 75 ohm coax. RG59 and URM70 cables will do the job although there are many others with higher spec (and price) that you can choose from. If you have to buy a pre-terminated cable, then choose the fattest cable you can find. It's not a scientific way of choosing the cable, but the diameter is normally an indicator of the quality of cable.
Asked in HDTV
Can you use RG 59 on digital TV?
If the interface requires a co-ax cable, then RG59 is perfectly acceptable for video signals. It is not the best choice for arial or satellite feeds. RG59 suffers from high losses and therefore, will not be the right choice for a long run carrying HD signals. If the cable length is more than a few feet, it is probably wise to invest in something with a lower loss if HD is used now or will be in the future.

How to avoid Y Pb Pr signal ghosting over long approx 60m distance?
High frequency signals such as component video are susceptible to signal reflections over long distances. The reflected signal will appear as a ghost signal to the right of the original image. Reflections can be eliminated by getting three things right: The signal source must be a 75 ohm source. All professional equipment and most domestic equipment should provide this signal. The cable must be 75 ohm co-ax cable. Low cost versions include URM70 and RG59 although better quality cables are available at a higher cost. For 60 metres, RG59 is likely to provide perfectly acceptable results. More expensive cable include the PSF range (a BBC standard used for analog and digital signals). PSF 1/3 will handle the length with ease. If the connectors needed are RCA, make sure the connectors are large enough to accept the cable. PSF is a large diameter cable. The last item is the input at the destination. It must have a 75 ohm impedance. If the source, the cable and the destination are all of the right type, the reflections will not be present. In domestic installations, a common problem is the use of screened audio cable rather than 75 ohm co-ax. If the cable is not a proper video cable, that is the first thing to replace. It is likely to make all the problems disappear but it is important to make sure the cables are terminated properly. Less common is that the video source or the destination ports are not properly built to handle 75 ohm cable. Some domestic equipment isn't because it causes no problems for short connections. If that is the case, the solution is to obtain a line driver and a line receiver. There are many available but a reliable choice at a sensible price might be one of the Kramer range of drivers. The driver can be connected to the output with a short lead and the receiver connected to the input, also with a short length of lead. Do not install drivers or receivers until you know that the cable is right.

Asked in HDTV
What is the maximum length of component video cable?
Standard definition component can run over relatively long distances. The maximum length is dependant on the cable, the source driver and the receiver. Using 75R co-ax cable, 100ft or more should present no problems at all. If the length is significantly more than 100 feet, it will be wise to choose a low loss cable (for low loss, read "more expensive"). With low loss cable, anything up to 500 feet is possible. Some cable suggestions are RG59 for lengths up to 100 feet. For longer lengths, consider a BBC specification known as PSF 1/3.

How to hook up 2 tvs from one soURCE?
Television sources vary but are commonly broadcast receivers such as satellite and cable receivers or digital terrestrial tuners. There are several options to connect additional televisions to a single source. First, consider the video and audio signals: If the source is a standard definition one with analog outputs, a simple video distribution amplifier will split the signal into to separate lines. The distribution amplifier needs to be chosen to match the signal type (composite, S-video, component or RGB). For the remote television, add good quality co-axial cables of the right length. Good cables allow a cable length of several hundred feet but be aware that many of the lowest cost video cables aren't as good as they could be. Look for cable that is marked with a cable type such as RG6, RG59, URM70 as examples. There are many other high quality video rated cable and the key is to find a cable that has a 75 Ohm characteristic impedance. Audio will need another pair of cables but unlike video, the cables are not critical and in fact, the audio source can usually be split and routed to both televisions without a distribution amplifier. Moving to HD signals, the connector will be HDMI from the source. To split it, you will need an HDMI distribution amplifier or splitter. They can be found on Ebay or Amazon among other places but beware - Both have hundreds of "HDMI splitter" units that in fact are switches to select one of two sources. Make sure you only get a splitter that is confirmed as a single input to two outputs. Also, there are a number of HDMI male to twin HDMI female adaptor leads. They DO NOT work and can only be used for one connection at a time. HDMI signals carry video and audio so no other audio is needed. HDMI cables are limited in length and for long runs, they get to be breathtakingly expensive. An alternative for long signal runs is to to use an HDMI over CAT6 or CAT6 converter. These use a pair of network cables instead of an HDMI cable and they offer a lower cost alternative to the longer HDMI cables. Finally, you will probably want to to control the source from both viewing locations. You will need an infra-red extender that receives the signal from a hand control and routes it back to the source and then to a small infra-red emitter which controls the source. This is a very general guide. Sources such as cable or satellite receivers or disc players may have slightly different outputs and you will need to be guided by the connectors on both your sources and televisions. The installation methods and cable choices will depend on the layout of your home to an extent and you may want to consult with a supplier before ordering equipment. While it is a relatively simple task to install a second television, doing some research on your specific equipment is well worth the effort. Always remember that all good equipment suppliers or home theater specialists will be happy to offer advice free of charge.
How do you join a cut rg59 cable?
If it's indoors you would go to the local electronics store (i.e. radio-shack) And pick up two RG-59 cable ends and a barrel connector (sometimes called a coupling) Just put an end on each piece of cable, they will come with instructions, and then screw them together with the barrel. You can also use wire nuts but it may cut down on the quality of the signal. Just strip off some of the outer sheath, and then a bit of the inner sheath. Twist the center copper wires together, and then twist the outer shield (silver mesh) together making sure that the copper wires don't touch the silver. If they do touch it won't do any harm, but it won't work.
How do you connect f coupling to rg59 to hook up cable for tv?
You will need a tool to crimp it properly. I have tried to crimp F connectors without this tool, and it is not worth it. You can get one at your local hardware store for around $20 and it will have detailed instructions on how to use it properly. Also the packaging the F connectors come in usually have instructions on the back.

What does coax mean?
To persuade or encourage. Coax a horse to drink. Try to get a horse to drink. Best used by saying "coaxed into" or, well yeah, you get the point. Like this: "Can I coax you into drinking from this cup?" "The coach coaxed me into joining the team" Are you speaking of coax, or COAX, as in coaxial cable? If so, a coaxial cable is a cable with a single central conductor surrounded by an insulator, finally surrounded by a cylindrical shield of fine wire. A coax carries high frequency signals (eg radio, video) and the woven outer wire shield is usually grounded to reduce interference. Most commonly, two types of coax are used in LANs: 50 ohm RG58, for digital signalling, and 75 ohm RG59, for analog and high-speed digital signalling.
Asked in Home Theater, DVD Players
When connecting a DVD to a projector is it better to extend the cable between the DVD and the projector or the cables from the DVD to the front left right and subwoofer loudspeakers?
The question asks, in a slightly round about way, whether long cables will cause losses in signal quality. It is safe to say that in a home theater, losses will not be an issue for almost any situation. As the size of the installation grows then cable losses become more significant. Generally, place the DVD player where it can be accessed easily without worrying about cable lengths. Below are some examples of cable lengths that are perfectly acceptable assuming that reasonable quality cable is chosen: Composite video, S-video, SD component, RGB (below HD resolution), using URM 70, RG59 cable or better can be run up to 100 feet or more without any noticeable losses HDMI or DVI using a single cable without joins can run up to 50 feet or up to 80 feet with high quality cable. Note that these distances are subject to good quality outputs from the source and inputs at the destination. Line level audio. Using good quality cable, distances can exceed 200 feet although mains induced hum may be a problem if the cable is routed close to mains power cables. Use a professional foil screened cable for longer runs and avoid very low cost cables - low cost means less copper screening and therefore more risk of noise. Speaker cable - up to 50 feet with ease but the longer the cable run, the larger the cable should be to avoid power loss in the cable. In most home theaters, there is more than enough amplifier power and some losses in speaker cables can be accepted. Note: The above does not cater for the purists who will choose to use very short lengths of very expensive cables to minimise losses. Those people will argue that the guidelines above allow unacceptable losses. The guidelines are ONLY guidelines. In some situations, the lengths can be extended greatly without noticeable losses and in others, it might be wise to reduce the lengths mentioned. Also understand that every engineer will have different views on safe cable lengths. If the lengths mentioned above are to be exceeded, it is worth getting advice from an engineer before proceeding.

What is needed to feed off-air tv broadcasts to multiple TVs?
There are two ways to route television signals to several televisions. The first is to use an RF distribution amplifier. These take a feed from an antenna and route it to several outputs. RF co-ax cable is needed to run from the amplifier to each of the televisions. Every television can receive any of the channels available through the antenna. The other method is to use a receiver such as a digital set top box, a cable or satellite receiver and take the output into a video and audio distribution amplifier. This works well for standard definition video but HDMI distribution amplifiers tend to be expensive and not all televisions will work with all amplifiers. This is due largely to the content protection systems employed in HDMI signals. HDMI of course is the only method of running HD signals in a domestic set up. Note that each television will only display the program that the receiver is sending out so there is not facility for multiple programs from the single source. Cabling for standard definition will be a video co-ax and a pair of audio cables. The co-ax should be a 75 ohm type such as RG59, URM70 or similar. RG59 tends to be the least expensive and for runs below 50 feet or so, is perfectly adequate. HDMI cabling must be bought a a complete cable assembly and prices rocket as the lengths increase. It's worth thinking carefully about what you want to distribute and how you go about it before investing in cable or hardware.

Suggest some minor project of electronic in BE?
There are literally thousands of projects you could do. It depends on your level of schooling (i.e freshman or senior). Assuming BE is Bachelor's of Engineering, and also assuming you are a freshman or sophomore the following are good project ideas (audio related): 1. headphone amplifier - CMOY type, small, great for using good headphones with portable music players. uses a good audio OP Amp (like Analog Devices OP275). 2. unbalanced to balanced audio transmitter and balanced to unbalanced audio receiver - great for transmitting audio signals over great distances while eliminated any noise picked up on the wires. The circuit inverts the audio signal 180 degrees and transmits the in-phase and out-of-phase signals on a pair of wires, the receiver inverts the out-of-phase signal providing 3dB of gain and eliminating any picked up noise by 70dB or more. 3. video switched 120V outlet - input is the output video signal from a tv, when a video signal is present, the circuit energizes a relay to give power to an amplifier or powered speaker system. with this the audio system will turn on/off with the tv. 4. an alternatve to #3 is a circuit that senses an audio signal instead - common auto turn-on circuit in modern sub amplifiers. 5. solar panel battery charger - intelligent battery charging circuit 6. HDTV antenna booster amplifier 7. UHF/VHF channel modulator - accepts any video signal over RG59/RG6 coaxial cable and modulates it to a cable channel in either the UHF or VHF band, while allowing standard cable operation. example - security camera at the front door can be viewed from any TV in the house on channel 54. If the product can allow for bi-directional signals and HDTV though Cable you'd have a product that you could market. There are two types of projects for an EE - analog projects and digital projects. There is a huge difference between the two. I have a BSEE with an emphasis in analog/digital communications and power systems. I did hundreds of projects in school, usually two at a time every week. Some projects lasted months, and each week we worked on a new part of the project (broken up into different parts that could be independently tested). Finally, the type of project you can do is dependent on the equipment you have on hand - i.e. oscilloscope, network analyzer, soldering iron, etc. Your project will be a success if the design is solid. A good design requries a deep understanding of the why's and how's.

Can you use R 59 wire for a satellite dish?
You can use it, but it can (and often does) cause the receiver and/or the LNB on the sat dish to malfunction. RG59 wire is not thick enough to carry 18 volts from the sat receiver box to the dish and will eventually cause one or possible both of them to fry from lack of proper voltage. Again, you can use it, but buying proper coaxial (RG6) will be much cheaper in the long run.
