Coaxial cables deliver or transmit signals from one point to another. It should be effective enough to have been considered as one of the basic and essential needs in transferring signals for decades. It is much like booking a cheap night in Amsterdam. You have to make sure that your room is reserved so that your day will be as bright as you imagined it to be when you are on your actual vacation.
When creating and installing this type of cable, you are going to consider a lot of parameters to ensure that you are maximizing its use as a transmitter of the signal. What are these parameters?
The physical parameters
If you are the one who is going to install the coaxial cable from the signal source to its destination, one type of parameter that you should consider is the physical parameter. This parameter is an obvious characteristic which you can easily check upon installation. First is the length of the cable. It is like determining how long your Amsterdam city trip will be. You have to understand that the longer the cable is, the higher the signal loss can be. Like any transmitting device, coaxial cables are not perfect. But it does the job even when it spans tens and hundreds of yards.
Another parameter that you should check is the outer diameter of the inner conductor. Coaxial cables transmit signals using these conductors. The higher the signal, the larger the delivery. But in contrast, as it goes higher, the resistance can also be greater.
Another physical parameter is the dielectric constant of the insulator. When you consider this in your computation, you have to check the material used for the cable. Usually, it is a mixture of different materials. And you have to use the constant for it.
The coaxial cable impedance
The impedance simply means its resistance arising from the internal and external effects on the cable. You have to make sure that the cable can sustain these resistances so that you can have a perfect delivery of the signal to its destination. To minimize the impedance, usually, the installers use a higher size of diameter for the conductor.
