What can I do with old coaxial cable?
Any metal recycling center will be happy to accept your copper-cored wires, and the more the better. BestBuy, Staples and other stores that electronics will help out with electronics recycling, too. In fact, they’ll accept most of your small electronics, in addition to wires and cables.
How does power over coax work?
Power over Coaxial (PoC) basically means that power for the camera is supplied by the DVR via coaxial video cable (RG59 or similar), this removes the requirement for separate cables and power supplies which would otherwise be needed to power your cameras.
Can coaxial cable be used for electricity?
Unlike the flat wiring and cables that carry electricity to lamps and appliances, coaxial cable (often called coax) is round and fat. It is not difficult to work with, but it does require a little more care and some special tools to run the cable throughout your house and make the necessary connections.
What is the difference between 50 ohm and 75 ohm coax cable?
For those who understand dB gain, 75 Ohm can lose as much as -1.1 dB compared to 50 Ohm per 100 feet of cable. In essence at 100 ft of cable, 50 Ohm is roughly 1.3x more powerful than the 75 Ohm in terms of maintaining signal coming from the same source.
Is it OK to use old coaxial cable?
If you’re cutting the cord those old cables will save you some money and they’ll probably work just fine. An older cable could have signs of corrosion, it could have been bent in the past, or it the connectors could be loose. If it’s been outside there could be water damage, even if you don’t see it.
Is power over Coax good?
Another benefit of Power over Coax is that it can greatly increase the length of cable over which you can run the camera. Whilst we don’t recommend running cables to high resolution TVI cameras over more than around 80m in length without special equipment, PoC extends this distance to up to 200m!
Why do I need a coaxial cable adapter?
Using a coaxial cable adapter is an easy and cost-effective way to change the connector-type of an already terminated cable or incompatible device connector. Pick an adapter that’s most suited to your domestic, satellite, or terrestrial signal installation needs. That’s the only way to solve your coax-cable-connector incompatibility problems.
Can a coax cable be used to power a satellite dish?
Yes, this should work fine. Even in its original application, the coax was probably carrying a DC bias to power the LNB on the satellite dish. Assuming it’s RG-6 cable, it should be good for at least 3 amps.
Can a coax cable be used as a HDMI cable?
You can use a single HDMI cable in place of about 11 coax cables; this is because you can use that HDMI cable to connect TV boxes, TVs, DVD players, and a host of other audio/visual receivers in your home.
Can a coax cable be used as a negative?
Using outer shield of coax cable as negative end of supply makes a lot of practical sense since it is frequently exposed at connectors and junction boxes, and it is advisable to maintain it as common ground.
