Many companies are still using coax cables to address cabling needs in residential projects. It is because of the diversity of its usability. You can get coax cables in a range of sizes and shapes. Manufacturers take protective measures to extend the life of the cable. However, you want to make sure that it is the right choice for you. In this article, you will learn how to choose the right coax cable.
Choosing the Right Cable
There is a range of options including Ohm coax cable, white coax cable, digital audio coax cable, digital coax cable and so on. Make sure that the cable pairs well with the device. Otherwise, the cable will deliver poor performance. Therefore, you have to consider the following factors:
The following are the two types of impedance in coax cables.
- 50 Ohms
- 75 Ohms
The 75 Ohms is used for video applications and 50 Ohm is used for data and wireless communication. A standard 75 Ohms comes with 22 AWG central conductor. It is a flexible cable. The 50 Ohm cables come with a 26 AWG central conductor. These cables are bulk cables used in situations in which the building of cable assemblies is required in a field. The flexibility of these cables makes them suitable for tight-fit uses.
You also need to pay attention to the operating frequency of the cable. As this frequency increases gradually, the signal moves away to the conductor’s shield. This causes the ‘skin effect’. This frequency dictates the following:
- The strength of the signal.
- The distance the signal will cover without a significant data loss.
When the operating frequency is higher, it will cover a shorter distance.
It decides the signal transfer strength. Make sure that the impedance of the load matches the cable’s characteristic impedance. This helps in achieving a better signal transfer.
When the signal travels over some distance, the cable experiences some signal quantity loss. A cable with a wider central conductor comes with a decreased attenuation factor and lower signal loss. Therefore, consider the cable attenuation while choosing a coax cable. Cable attenuation is acceptable in certain conditions. However, attenuation can be a source of several issues.
External factors also affect the performance of coax cables. Therefore, you should consider the environment as well. The cable performance declines due to heat, water vapors, humidity and other weather conditions.
Coax Cables Wiring in Residential Areas
After you are aware of the factors to be considered for choosing a coax cable, it’s time to set up the cables. These cables are suitable for cable TV and internet hookups. However, many property managers and homeowners face some problems during the installation. Here are some tips for you:
Consider the Surface Area you Need to Cover
First of all, analyze your property and create a plan. Take note of the areas receiving the least and most amount of traffic.
Use a Cable of Extra Feet
Measure the distance you will cover with the coax cable. Now, you have your numbers. Make sure that the cable is a few inches longer than what you need.
Lookout for Obstacles
Installing cables requires drilling through the walls. However, drilling may damage pipes and electric wires. Therefore, it is important to consider potential obstacles. In addition to causing damage to the property, drilling can also cause injuries.
Consider the Available Egress Options
Sometimes, people pass cables through open windows and doors while installing coax cables. However, cables are prone to damage due to the high amount of traffic and opening and closing of windows and doors.
Use Color Code for Identification
You must use color codes if you have to deal with a bunch of cables. Color coding makes it easy to identify and connect cables correctly.
Consider the Legal Status
Make sure that you are aware of the local legal codes related to the use of cables in residential areas. You may get into legal troubles if you don’t follow the legal guidelines.
