As far as wiring up electronic components is concerned, there should be nothing to hold you back when choosing between 75-ohm and 50-ohm coaxial cables. This is because each are specifically suited to carry out particular electrical functions. Once you discover the ideal applications of all sized coaxial cables, you will be able to determine whether 75-ohm or 50-ohm coaxial cables are suitable for you.
Understanding 75 Ohm
Applications for a 75 ohm coaxial cable includes video and audio, accounting for its widespread use and adoption in the real world. A maximum installation size for homes and small structures is about 5,000 sq ft. They work pretty well for various home applications, which may reach 50 feet cables. A figure, which is recognized for varieties of coaxial signal connections with a high frequency is impedance of 75-ohm. Impedance is basically the measurement of electrical resistance, serving as the alternative current. This alternative current often flows into cables when alternative voltage is present at one end of those cables.
Understanding 50 Ohm
The smaller the ohm, the better a cellular signal booster performs – interesting, right? This simply means a system with a 50-ohm is much stronger than systems with 75-ohm. Although 50-ohm is stronger, it won’t be necessary for many small buildings or homes.
Choosing between 50 Ohm and 75 Ohm
So, what’s right type for you – 75-ohm or 50-ohm coaxial cable? Here is what we advise.
Opt for 75-ohm coaxial cables if:
- You want the right solution for small buildings and homes.
- Your home is pre-wired using F-connectors.
- Home coverage is below 5,000 square feet.
- Your cable runs are below 50 ft.
Go for 50-ohm coaxial cables if:
- You want the best solution for commercial spaces and buildings.
- You only need the best cables in terms of power.
- The building coverage is between 7,500 square feet and 100,000 square feet.
- Cables runs are over 100 feet.
What This Means in the Real World
If you always keep tabs with what’s happening with cellular signal boosters, it will be easier for you to understand how they work in different settings. For instance, professionals use coaxial cables with 50 ohms in commercial settings. In home settings, you will see experts using cables with 75 ohms. Do you know why? If you use a wrong cable, you will risk losing a lot. Not to mention, the devices you will attach the cables to have a high chances of not working. That’s why, if you want a permanent solution, make sure you go for the right cable.
In conclusion, professionals prefer using 75-ohm coaxial cables for homes as well as buildings with small spaces. This is because they have cable runs of below 50 feet and use F- connectors. However, in commercial buildings, experts use coaxial cables with 50 ohms. Unlike 75-ohms, these types have cables runs of over 100 feet and use N-connectors. This makes cables with 75-ohms ideal for professional settings characterized with large buildings.
