Always use co-ax connectors if you possibly can. Co-ax is manufactured to have certain electrical charactersitics and the connectors are designed to retain those characteristics thought the length of the connection. Ideally, BNC connectors should be the first choice but there are several others that can be used. Most co-ax connectors need specialist tools to make off, but there are some screw on BNC connectors available that can be used without the specialist crimping tools normally used. If the cables are connected with the wrong connectors or by being twisted together, then the signal will be adversely affected. How bad the effect is dependent on the length of the cables and how bad a job of splicing has been done. It might be as little as a faint ghost image that isn't noiceable or it could be enough to completely corrupt a signal.
To extend a coax cable without special tools you will need a second coax cable. You can plug the second coax cable into the end of the first one (the end that is plugged into the wall).
Cable modems use RG-6 coax cables.
It depends on how many wires are in the cable. The more conductors in the cable set the longer it will take to splice them.
coax.
This would depend upon your TV and the receiver and if it has a coax port available on the back. You can use an RG6 coax cable between the receiver and TV. Most newer HD receivers do not have a coax port on the back
The best size is RG 6 coax. However for short runs RG 59 will work.
For Dish Network, we use RG6 coax cable to allow a higher frequency range for the satellite signal from the dish to your receiver. Any coax cable not rated at RG6 could affect the signal.
It's the coax cable used for Thick Ethernet.
Typical coax cable uses a different standard than RCA. You will need to use a converter box.
Someone who installs coax for a service.
UTP & COAX cable's are used
No. The cable provider has to authorize the other modem on the network before it can be used, and they will not do that, since they want you to pay for another cable installation.
