Sharp bends will damage a cable. Think of wrapping a cable around a coffee can; coaxial cable should never be bent sharper than that. Use a degree adapter when a sharp bend is unavoidable, like behind a TV stand. Just make sure the connector is rated to handle Hi-Def if that's the signal you're working with. Does the coaxial cable matter? Coaxial cables can be used to carry signals for internet connections, but internet signals run at higher frequencies than traditional analogue video. It has a larger conductor, which provides a much better signal quality, and the dielectric insulation is thicker.
Is rg11 better than rg6? RG11, because of its bigger size and better handling of attenuation, is superior when it comes to preserving signal quality than RG6. It's also able to work at much higher frequencies than RG6 due to it having less signal loss. RG6 is the more familiar standard, particularly when it comes to satellite cables. Can multiple TVs use one antenna? Once you have your Antenna all hooked up, the next thing you need to do is connect a coaxial splitter. This is an inexpensive device designed for splitting an antenna signal to multiple TVs.
This lets you use one antenna for multiple TVs, so you can watch your local channels on every television in your house. How do you attach coaxial cable to wall plate? Twist the connector for the end of the coaxial cable to the back of the connector on the coaxial wall plate. Place the wall plate against the wall and over the low-voltage mounting plate. Use the screws that came with the coaxial wall plate to attach it to the mounting plate.
Does rg6 work on satellites? RG6 cable is thicker, has a thicker dielectric and a thicker center conductor. These small signal losses are usually less than half a decibel, but they add up. Especially when you start including union fittings, wall outlets, a cable from the wall outlet to the set top box, the set top box itself, then a cable from the cable box to the TV.
So as a rule of thumb, most installers expect each splitter to add between 3. When coaxial cable is used to provide a home with both broadband internet and television service, the installer will usually route one of the outputs from the first splitter to the cable internet modem, and then use the other output to split further for multiple TVs. You can see why in Figure 2. This arrangement provides the strongest signal to the internet modem, which is where most users need the greatest bandwidth.
Now that we understand a little bit about decibels from looking at the effect of splitting the signal in half, we can talk a little bit more about attenuation of the cable. Sticking with the same pattern, does a loss of Actually, they still do. When we look at that range of frequencies in Table 2, we can estimate that the signal loss for those channels is between about 1. Compare that to the signal frequencies from satellite TV providers, which can be as high as MHz.
And those are compressed signals. So if all you need are the soap operas from that old NBC affiliate on channel 4, then put your antenna out on the barn, down the road a piece, or even share it with your neighbors.

You do not want to introduce an amplifier after the resistance from the cable length has caused to drop the signal too low, as the amplifier would be trying to boost something that is not there. If you need to amplify the signals to very high levels like is the case for communal TV systems, you will need a professional launch amplifier to do this which can carry a high signal strength through it.
Simple satellite line amplifiers can be installed which has a sloped signal gain to remove sloping and are powered by the satellite receiver can be installed to overcome signal losses on long cable lengths. If you have a very long distance that you need to send a TV signal, consider using fibre optic cabling instead which distributes the signal using light rather than copper conductors.
This means that there is virtually no signal loss at all between optical transmitter and receiver. The excess can simple be coiled at either end. You simply take the frequencies that you wish to carry down the cable.
The same process should also be performed for the lowest frequency and mid-range frequency to identify any potential sloping or signal imbalances in the TV system. To do this:. As you can see from this article, that this is a difficult question to answer as there are multiple factors that effect how far you can send a TV signal down a coax cable. This includes quality of the cable, size of the centre conductor, the frequency that you wish to send down the cable, whether amplification will be introduced or not.

That being said, I will help where I can and I hope you liked the article. Cable Losses Increase With Frequency The higher the frequency the signal on the coax antenna cable, the greater the signal losses will be.
Signal Sloping The difference of signal losses over coax cable length can be very problematic in large TV systems and long cable runs as you have to consider signal losses at different frequencies on the same cable. Overcoming Signal Sloping Overcoming signal sloping is very important as you may have a good signal on the services that use the lower frequencies and a very poor signal on the higher frequencies.
Install Amplifier Before Signal Is Weak You want to install your amplifier in a location where the signal is still of an acceptable strength, before cable losses have taken effect. Satellite Line Amplifiers Simple satellite line amplifiers can be installed which has a sloped signal gain to remove sloping and are powered by the satellite receiver can be installed to overcome signal losses on long cable lengths. Consider Fibre Optic Cabling For Very Long Runs If you have a very long distance that you need to send a TV signal, consider using fibre optic cabling instead which distributes the signal using light rather than copper conductors.
To do this: 1- Find the highest frequency that you wish to carry through a coax cable. September 29, September 18, September 6,
