Can coaxial cables interfere with each other?
Coaxial cabling consists of a single copper conductor inside of a braided metal shield surrounded by a plastic outer layer that provides insulation to the cabling. The inner metal shield helps block interference, including electrical and signal, but coaxial cable is still susceptible to interference.
Can you connect two aerials to coaxial cables?
If the digital signal is weak there is no substitute for a masthead amplifier. Just stuffing two cables into one aerial will reduce the signal strength by at least 50% on each and probably more due to the impedance mismatch. It will also affect some channels more than others.
How to avoid or fix a ground loop?
Quite often I get questions about how to avoid or fix a ground loop situation when using Ethernet cable. It is great that people are reading Shielded vs Unshielded Cable. That is the starting point. Knowing you could run into this issue is half the battle. Fixing or avoiding it is the other half.
What do I need to ground my coax cable?
Get a grounding block along with a connector. The connector will be attached to your cable line. Use a grounding wire of the right thickness and size to connect to the grounding block and then run this to the ground. It will ensure that the signal doesn’t weaken.
Can a USB cable cause a ground loop?
Connecting two ac powered devices with a USB cable can cause a ground loop that disrupts communications through the bus. USB communication occurs over a single bidirectional differential pair (the D+ and D− signals in Figure 3). A host device controls the bus and communicates with a peripheral.
Why are ground loops bad for data transmission?
Transmitting data over long distances is fraught with potential problems. A ground loop can be a source of interference that can induce a noise voltage between the grounds on either end of the transmission. If this voltage is large enough, it can cause data errors at the receiver.
