How can I connect two coax cables easily?
Since there are hundreds of different types of coax, it will depend on the type of coax and what you’re using it for.For general purpose around the house coax, then depending on the RG type (Radio Guide), you can purchase connectors for it (e.g. F-connectors for RG-6, RG-11, and RG-59), then a female to female connector to connect them. You can pick these up at most hardware stores. You’ll need some tools to make the connection but the stores carry those as well.If it’s for amateur radio, then you’ll need to get some good, high quality connectors and probably do some soldering. Check with your local amateur radio club for help.If it’s for something else, then you should talk to someone qualified, especially if high power RF is going through it. There are safety considerations.
Is it possible to convert an HDMI into a coaxial cable?
It is certainly possible to convert HDMI to another type of signal. However, Coax is not a signal. coax is a type of cable that will carry several different types of signal, all of varying qualities. The highest quality signal over "coax" is HD-SDI or SD-SDI. This is a broadcast level digital signal, and can be either HD or SD Only the most expensive monitors or display devices have an HD-SDI input. The input is BNC 99.9% of the time. Another type of more "coax" signal is composite video. This signal is the yellow connector and is usually an RCA type connector. Composite video is always standard definition. Lastly, there is RF. This signal used to be the lowest quality, and was the standard in TV transmission until the digital changeover in 2009. This is the Screw type F connector. Before that time, it was always standard definition. Since the transition, it can be HD, but must be Digital RF. In order for an older TV to read Digital RF, it must have a QAM tuner either internally, or externally. Now comes the HDMI part. It can be very frustrating to try to convert HDMI to anything because of HDCP compliancy. HDCP is (very simply defined) Hollywood's way of controlling how their content is displayed. Every device in an HDMI chain must meet HDCP compliancy. If even one device is not, the content will not display. There are several other HDCP issues, which can be found on Extron.com. Most devices that convert HDMI to something else will not allow movie content in HD to pass. If you happen to have "ripped" movies, the easiest (though far from cheap) way to convert is with some sort of HD modulator (ZeeVee makes one as well as Contemporary Research). By using this type of device, you are essentially creating your own closed circuit TV system. Though this may sound cool, it is pretty expensive, and probably not the answer you are looking for.
Difference between RCA & audio coaxial cables?
"s there any difference between a regular RCA connection audio cable (like the stereo red/white ones) and the ones you use for digital coaxial audio connections?" Yes. Video cables and coaxial-digital cables must be made with 75 ohm coax. Audio RCA cables can be made with any of the popular coax like 50, 75, 110, 300. As long as the L/R are the same, the lower speed audio signals dont care about the impedance. The SPDIF was designed around using a video cable with 75 ohms impedance for the coaxial-digital connection. SUBWOOFER CABLES: A normal RCA cable works great for subwoofers. But sometimes you get hum with an ordinary cable. This is because the subwoofer has an amplifier and the AV Receiver has an amplifier. A normal RCA cable ties the signal ground from these 2 together. The two amps 'fight' over who is the source of 0.000 volts and this is called a 'ground loop'. A "subwoofer cable" with little arrows is really a broken RCA cable. The shield is not connected at one end. This keeps the two amplifiers from seeing each others ground and solves the ground loop problem. "if I buy the specialized cables will I notice a sound enhancement?" Generally no. But does the 5.1 sound drop out every few minutes? People have used an audio RCA cable for the coaxial-digital connection and it appears to work. But they noticed the sound skips/drops out every so often. Using a proper 75 ohm video cable solved the problem.
Is coax cable, the basic wire in every home, a digital or analog wire?
Coaxial cable can carry electrons at high speed and those electrons can be used by either digital or analog systems, depending on how they were sent and how they are decoded. It is only a transmission medium; how we transmit through it is up to us. It's features work well for both analog and digital signals, although like most transmission media, 50% (average) duty cycle signals usually transmit with fewer errors. While most transmission media can't be classified analog or digital, fiber optics come the closest. Originally designed to transmit light pulses (not constant beams), it is optimized for digital transmission -- but, with the correct transmitter and receiver circuits, it can be used to transmit non-digitized analog signals.
Is there a BNC female coaxial adapter that can convert to an HDMI cable TV?
BNC is not a signal type, it is a connector type. For Video, cable terminated with a BNC can be either SDI (lots of varieties) Composite video, part of component, or part of some other multiband signal cable bundle. For Audio, BNC connectors are used for timecode, and on some older digital audio formats. It can be of the 50 Ohm variety and can be used for antennas.To answer your question, yes, there are SDI to HDMI converters and there are Composite video to HDMI converters. Check out AJA.com, Blackmagicdesign.com, and Decimator.com. All of these brands (and many more) have some type of converter that may fit your needs.
Is there a such thing as a coaxial to USB femal adaptor?
A coaxial cable can be used to carry many different types of data. The data is coded in an analogue signal format specific to the type of data, before being carried over the coaxial cable.It’s certainly possible to convert between coaxial and USB without knowing anything about the data the coaxial cable is carrying. This adaptor does exactly this:The adapter converts the analogue signal on the coaxial cable to a digital representation of this signal carried over USB. There are a number of problems with this approach however, not least:Most signals carried over coaxial cable are designed to be received by a hardware decoder of some form to extract the original data. This hardware decoder efficiently decodes the specific analogue signalling used for this type of data. Without this decoder you’re left with having to process the “raw” signal in software to recover the data. This is inefficient and there’s no demand, and so such software decoders are not generally available.Some signals carried over coaxial cable vary too rapidly to be captured accurately by a device such as the one above, mainly due to the limited data transfer speed of USB. In these cases there is no option but to have a specific hardware decoder to decode the signal and extract the data before sending over USB.So the general purpose device above is designed only to allow the raw analogue signal on the coaxial cable to be captured and observed on a screen for diagnostic purposes, and only works for a limited range of signals. To actually decode the signal and make use of the data on your PC you need instead to use a converter/adapter which is specific to the type of data being transferred on the coaxial cable.Coaxial cable is used for a huge range of different data, but the types that a typical home user is likely to come across are:TV or radio signals carried over coaxial cable from an aerial. Here’s an example USB adaptor for digital TV:Cable (as in CATV). There’s no choice but to use a cable box or modem for decoding cable signals and recovering TV or broadband, although you could then use a USB adapter to connect either of these to a PC.Video signals from, e.g., a cable box or video player. These require a video capture adaptor such as one of these:Audio signals, either analogue or digital. These require an audio capture adapter such as one of these:
How can you extend the lenght of a coaxial cable?
Coaxial cables can be extended by any number of different methods, but there are some things that must be considered such as the type of coaxial cable ( i.e. RG 59; Rg; 6: RG 9; Rg; 11; or specialized multi-tube cables; ect; then the type of signal(s) that will be traveling over the particular coaxial cable( i.e. digital; analog; TDM: FDM: or multiple; finally the length of the extended cable beyond the the current length; and lastly the total over-all length of the cable, but most importantly is the originating signal levels, and the signal level at the point of the where the extension is to take place. Every cable has a signature or varying losses under different signal conditions. Every cable can be mechanically coupled as described by the others or physically spliced if done properly, but losses and impedance will determine whether your extension is actually going to work. You might need to add an amplifier or repeater ( analog or digital). In line Filters might be required or RF shunt capacitors. The simplest answer is what are you trying to extend, and for how long. Is it indoors and what’s the incoming signal strength? Please give specifics otherwise you’ll receive erroneous answers. I.E. If you use a barrel connector and run a piece of RG 59 fifteen telephone poles down the road you’ll probably be very disappointed, and you’ll endanger a lot of lives.
What is the easiest way to extend a coaxial cable?
It’s very difficult to properly splice two coaxial cables together, esp. without having an impedance discontinuity at that point, so both the easiest and best way to extend a cable (outside of simply using the correct length of continuous cable in the first place) is to terminate the cable in an appropriate impedance-matched connector, and add another length of cable via a mating connector on that cable. For instance, you might terminate a 50 ohm cable via a BNC male, and add a second length (also terminated in a BNC male) using a BNC-to-BNC “barrel” connector:(In this case, such a connection is more common that trying to terminate the next length of cable with a BNC female, as it’s a good deal more difficult to find a BNC female intended for cable-end use.)
How to extend TV coaxial cable?
If you’re serving the TV signal to a single TV set or outlet without splitting the signal, then all you really need is an F-female-to-F-female connector.If you need to split the signal and extend it (either because your home uses daisy-chained cabling, or because you need to serve the signal to multiple remote TV sets or outlets a long distance away), then you’d want a directional coupler. A directional coupler is different from a splitter, in that it can be tapped and split locally while preserving a higher power ratio for transmission to the remote location(s) for further splitting. Models can vary by decibel loss, the number of tap ports, and whether a port is available for monitoring signal reflectivity, but the minimal design is “In,” “Out,” “Tap.”In general, you want to make sure that the frequency range covers only the frequencies you need. For DBS satellite TV, that might be 5–2300 MHz. For ATSC and QAM cable TV, that might be 5–1002 MHz.
