Which Is Right for You: 50 Ohm vs. 75 Ohm

Knowing what coax cable you need helps you find the ideal cellular booster that suits your needs. For some individuals, 75 Ohm works, but others need 50 Ohm. By better understanding what these are and what Ohm is, you can make finding your ideal booster kit a breeze. Discover the differences between 50 Ohm and 75 Ohm to know which is right for you!


What Are Ohms?

Noting the Ohm of a cable and what you need is important because it measures the electrical resistance. However, you don’t need to get into the nitty-gritty of calculating Ohm to find the ideal booster cable. What’s most important is knowing the difference between 50 Ohm and 75 Ohm.


50 Ohm

Interestingly, the smaller the Ohm number, the better the booster performs, so systems with 50 Ohm are stronger than those with 75 Ohm. While 50 Ohm is stronger, it isn’t necessary for most homes or small buildings and covers anywhere from 7,500 to 100,000 sq ft. Likewise, these cables run around 100 ft. long.


Understanding the various cellular signal booster cables can help you decide whether 50 Ohm or 75 Ohm is suitable for you. Cables with 50 Ohm are more powerful than those with 75 Ohm so that they can enhance the signal in a large space. Also, these cables have N connectors to keep the antenna and booster hooked up.


Who Buys 50 Ohm?

Typically, owners of large commercial buildings buy booster kits with 50 Ohm, but anyone can purchase them. Some owners of smaller homes may live in rural locations and need a stronger system to keep connected. Whether you buy 50 Ohm depends on your needs, home size, and location.

75 Ohm

In a building under 5,000 square feet, systems with 75 Ohm work perfectly fine. Most experts agree that this is ideal for most home and small business owners. However, it’s worth noting that there is a -1.1 dB loss with 75 Ohm; for this reason, it’s not ideal for everyone. Most of the time, homeowners buy an RG-6 or RG-11 cable for their booster, which both offer 75 Ohm.


Noting the differences between 50 Ohm and 75 Ohm allows you to better analyze which fits your needs. Often, homeowners buy systems with 75 Ohm but may need something stronger if they live in a rural area.
