Coaxial Cable FAQ

A coaxial cable is a type of cable that uses an inner conductor wire and an outer shield. The shield helps to protect the signal from external interference and noise. Coaxial cables are often used in networking, telecommunications, and other electronic applications.

Coaxial cables are designed to carry signals in the frequency range of about 50 MHz to 8 GHz. They have a single conductor (the center wire) that is surrounded by a dielectric layer, which is in turn surrounded by a conductive shield. This shield protects the cable from external interference and keeps the signal confined to the center conductor.

RF cables, on the other hand, are designed to carry RF signals of much higher frequencies, typically up to about 18 GHz. They have two or more parallel conductors (the center wires) that are each surrounded by their own dielectric layer and shielded from each other. This construction allows for better transmission of high-frequency signals.

There are a few different types of coaxial connectors. One type is the F connector, which is used for cable and satellite TV. It has a threaded connector and two bayonet lugs. Another type is the BNC connector, which has a locking mechanism and can be attached and detached with a single hand. It’s often used in video applications. There’s also the TNC connector, which has both a threaded connector and bayonet lug, as well as the N connector, which is similar to the BNC connector but doesn’t have a locking mechanism. Lastly, there’s the SMA connector, which has a threaded connection and is often used in microwave applications.

There are a few common sizes of coaxial cable, the most popular being RG-6 and RG-59. RG-6 is often used for HDTV and satellite TV installations, while RG-59 is more commonly used for CCTV applications. Other sizes include RG-11 andRG-8, which are typically used for commercial applications.

The maximum length of a typical coaxial cable is about 100 meters (about 328 feet). The limit is mainly determined by the attenuation of the signal over distance, but other factors such as interference can also play a role. In very long runs, it’s usually necessary to use amplifiers to boost the signal level.

Generally speaking, RG-11 coaxial cable is used for carrying high frequency signals over long distances. This type of coaxial cable is often used in applications involving Ethernet or fiber optic cables. In terms of specific applications, RG-11 coaxial cable can be used for CCTV camera installations, baseband video signals, and RF distribution. Thanks to its construction and low loss properties, RG-11 coaxial cable is also well-suited for use in networking and telecommunications applications.

When it comes to choosing the right type of coaxial cable for your needs, it is important to consider the frequency of the signal that will be carried by the cable as well as the distance over which the signal will travel.

The two most common types of RF coaxial cable connectors are the BNC connector and the TNC connector.

The BNC connector (Bayonet Neill-Concelman) is a simple and reliable connector that uses a bayonet mount to attach and detach the connector from the cable. The TNC connector (Threaded Neill-Concelman) is also a simple and reliable connector, but it uses threaded fittings to attach and detach the connector from the cable.

A micro coaxial connector is a type of coaxial connector that is used for connecting micro coaxial cables to facilitate high-quality, low-loss connections between electronic devices such as medical implants and camera lenses

The connector consists of a small-diameter (micro) central conductor and insulating dielectric material, which are surrounded by a braided metallic shielding. The shielding minimizes the amount of electromagnetic interference (EMI) that can be transmitted along the cable.

The micro coaxial connector has a number of advantages over other types of connectors. It has a high bandwidth capacity, which enables it to transmit data at high speeds. It also has low insertion loss, so little signal power is lost as the signal travels along the cable because it has excellent EMI rejection capabilities.
