Every minute counts in a business, and damaged, degraded coaxial cables can slow down daily operations. Wireless connections are great for on-the-go communication, but coaxial cables offer reliable frequency transmission, which is essential in many business and industrial settings.
An integral part of any data network, coaxial cables are responsible for transmitting signals used in cable television, high-speed internet, and much more. If you’re considering a coaxial cable upgrade or installation, contact us today to tell us more about your project requirements.

Coaxial cables are used to transmit frequency signals between different components, devices, or systems. Unlike other electrical cables, these pass radio frequency signals instead of an electrical current. They are made of copper, metal shielding, and other components to block signal interference improve communication.
Many coaxial cables have a copper wire and woven copper mesh separated by concentric insulation layers. These cables are ideal for offices and spaces that require quick and efficient high-speed Internet, phone, or cable services. Electricians and contractors differentiate the cables by looking at various qualities, such as:
The signals that coaxial cables are responsible for transmitting can be mission critical for many businesses. If you don’t hire a licensed electrical contractor to install your coaxial cabling, you might experience problems with your phones, TVs, Internet, and any devices relying on these services.
Some property owners believe that since coaxial cables don’t have the same risks as dealing with other electrical wiring, a licensed electrician might not be necessary for the installation. Don’t risk losing your time and money by cutting corners when running coaxial cables. Contact us today to schedule a site visit.
Cable and Internet providers often lack the qualifications or clearance to do any internal wiring on a building. While cable installers may try to hide cables behind furniture, in most cases, cable providers simply won’t open walls to run wires because it makes the job more complex.
An electrical contractor has the skillset necessary to open up walls to discretely run cables, and in most cases can provide basic repairs to close the wall back up. In addition, if any additional outlets or jacks are needed to complete the installation,
There are a lot of hidden complexities in coaxial cable installation. Selecting the right cables, running the cables properly, installing new connectors, and anything else that may be required during installation all need experience and expertise to be done right.
If done incorrectly, you could find yourself dealing with regular signal disturbances, distorted pictures on your televisions, and even shock hazards or fires if anything was improperly done when installing the connectors or outlets.
While all coaxial cables have the same job, some are more efficient with specific signals than others. Some also carry different functions, such as landline or cable TV use, which may require a different mesh or material size. Because of this, more than one type of coaxial cable exists for the best effectiveness based on their use. An experienced electrician will know which to use that will best fit your cabling needs.
Hard-line cables use a center conductor wire or braid made of different metals, like copper, steel, silver, or aluminum. The protective layers make them ideal for high-strength signals like military radio transmissions.
Triaxial cables, also called triax, are similar to hard-line cables but have an additional layer of metal mesh and insulation. This layer helps increase bandwidth capabilities and decrease outside signal interference.
Rigid-line cables contain two wires in the center instead of one, with PTFE disc insulators throughout the middle. Their dual-center allows rigid-line cables to support multi-channel transmissions for TV and FM frequencies.
Radiating cables are similar to hard-line cables except there are slots cut into the mesh covering the inner insulation to allow certain frequencies to leak through. Thes cables are ideal for places like tunnels or mines.
The cables and their connectors have different qualities to accommodate specific signal needs. A professional technician will know what cord best benefits the job as they complete a coaxial cable installation. An experienced eye and mind know to consider the following:
Each cable works best with a specific kind or range of use. Some only function with particular machinery or specialized applications, while others exist for general use. Some cables also work best for short-range transmissions at a low frequency, while others channel long-range at high frequencies.
Just as some cables function best with different applications, they often have optimizations for a specific environment. For example, some cables have hardened polyethylene coatings to protect them from sunlight. Electricians also consider environment-related safety, such as using weatherproof pipes to run the cables in underground spaces.
Impedance is the amount of resistance an electrical circuit has to signal at specific frequencies, expressed in ohms. A careful electrical setup should ensure that the components in a coaxial cable system resist and accept the desired frequencies. This process helps provide clear communication between the signals and the equipment, preventing signal disturbances like audio cutting or “ghost” images.
Very high and ultra-high frequencies, VHF and UHF, can affect coaxial cables and cause them to lose signals. Some manufacturers add foil or braided shielding to protect them from frequency interference. It is up to the electrician to use the most protective and reasonable cable for the job.
The voltage of a cable is the amount of electrical pressure the wire or conductor within the cable can handle. Each one has a maximum voltage amount it can channel safely, which manufacturers often list as a slightly reduced number. Electricians install cables that can handle the necessary energy to avoid any signal disruptions.
