Coaxial cables were first invented 142 years ago and have been employed to transmit high-frequency electrical signals over long distances at low signal loss. These cables have many purposes, including telephone trunk lines, cable TV signals, and cell phone boosters. There are many lengths and sizes of coaxial cables, each one designed for a specific purpose.

A coaxial cables is composed of an inner core and an outer core. They share a common geometric axis. This prevents electromagnetic interference and allows for reliable data transmission over longer distances.

How is a coaxial cable constructed?

Coaxial Cables are made of a single copper wire or copper-coated steel core that carries the high-frequency signal. Additionally, these cables are protected by a dielectric insulator, usually made of plastic. This is meant to keep the distance between the center conductors and the next layer constant. This shield is made from woven copper, aluminum, or other metal and cancels electromagnetic interference. The final layer is a rubber wrapper, which insulates the whole configuration.

Coaxial cables can be applied for both indoor and outdoor applications. However, the outdoor coaxial cables needs extra insulation to protect it from external factors that would damage it quickly. Coaxial cables used in the exterior of a house may run from your home to a satellite dish or the box at the corner; consequently, they must be protected so they can transmit seamless data, no matter where they are placed.

How do coaxial cables work?

A coaxial cables transmits a signal that runs across both the copper wire and the shield. These two metal conductors create a magnetic field. The insulators prevent signals from being in direct contact with or canceling each other. The insulators protect the signal against magnetic fields from outside, allowing it to be carried over long distances without any interference or signal loss.

Difference between the RG58 and RG174 coaxial cables

What are the uses of the RG174 cable?

This type of coaxial cables is commonly employed for many applications nowadays.  The cable’s 2.5mm outer dimension allows for the attachment of most micro-coaxial connectors, making it ideal for cellular communications,  WLAN, and GPS.

Like in most coaxial cables, the structure of RG174 consists of the following layers: Central conductor: 7 strands of stranded copper-clad steel with a diameter of 0.19 inches. Dielectric: Low-Density Polyethylene, which adds flexibility and water resistance to the cable.

What is RG58 Cable used for?

RG-58 coaxial cables are mainly used for wiring purposes since this cable is an excellent choice for high-frequency signal transmission. It can also be employed in antennas and broadcasting equipment.

What is the difference between RG58 & RG174?

Both RG58 and RG174 cables are ideal for vehicle boosters, so knowing how to differentiate them might be confusing for many. However, the difference is in the RG58’s longer cable length of up to 20 feet and the RG174’s 6 feet. Consequently, the RG174 is better for large vehicles such as boats or RVs. Another difference is found in the RG58’s superior low-loss quality.

Both are equipped with SMA connectors. These connectors are small copper connectors that are used in modems and other similar devices. These connectors are relatively cheap, which makes them more affordable.
