50 OHM or 75 OHM - Which is the best?

50 OHM or 75 OHM - Which is the best?

Written by Sadia Jahangir

How much is an Ohm?

There are only two factors to consider when comparing 50 Ohm to 75 Ohm: footprint and strength, especially in relation to coax cables with 50 versus 75 Ohm resistance. In a nutshell, the impedance of a cable is the amount of resistance it presents to the flow of electrical energy. Boosting cellular signal is much easier with a 50 Ohm cable than with a 75 Ohm cable.

The radio frequency you are attempting to transmit heavily influences the difference in signal loss between 50 and 75 Ohm cables. Certain 75 Ohm cables perform better than 50 Ohm cables at extremely high frequencies.

However, common 50 Ohm solutions (Wilson400, LMR®600, etc.) can be used to boost cellular signal always provide better loss than RG-6 or other 75 Ohm cables.

Here is a manual for more modest 50 Ohm links and their frequencies, which much of the time have a more serious level of sign misfortune than the normal RG-6. The majority of home cellular boosters come with 75 Ohm cables, such as RG-6 with F-connectors, and 75 Ohm systems.

The majority of commercial cell signal boosters have 50 Ohm cables, like the LMR®400 with N-connectors. In terms of wire and connector width, there is a significant physical difference between the two, as shown in the image above. We’ll talk about the main differences here.


75 Ohm: The acquaintance you already know

Why think about 75 Ohm?

This is due to the fact that 75 Ohm cables are the most common type of coax cable found in offices and homes alike. They are frequently used and frequently come prewired in many homes and businesses, from the back of televisions to cable and satellite television boxes and internet routers.

75 Ohm is quickly becoming the national standard because it is primarily used for audio and video. They are perfectly capable of transmitting signals up to 50 feet of cable for home or small building applications, with a maximum installation area of 5,000 square feet.

Bftsync’s best-selling 75 Ohm cell phone amplifier system is the weBoost Home Multiroom:

  • Complete coverage across all carriers for large households or many rooms with various devices that are 5G ready
  • In ideal circumstances, coverage can reach 5,000 square feet.
  • Gain of up to +65 dB, up to 21 dBm uplink, and down to 12 dBm downlink
  • Configuration of an inside panel antenna and an outside Yagi antenna with elegant fabric front
  • There are numerous attachments available for the greatest coverage and customization (sold separately)

The most well-liked signal booster of Bftsync is the weBoost Home Multiroom, and for good reason. It has a coverage range that typically suits the needs of most people and is priced, aesthetically pleasing, and efficiently at the sweet spot.

A panel antenna, a strong amplifier, and a Yagi antenna are all included in the kit. It can reach distant towers and cover many rooms or an entire house thanks to its high output capabilities and gain of up to 65 dB. Both city dwellers and residents of rural areas, where tower distance is a major issue, should consider it. It provides coverage of up to 5,000 square feet under ideal circumstances. The average size is between 2,000 and 3,000 square feet, though. Less can be expected in places with terrible cellular reception.

The weak signal situations should give this lower grade booster some thought. Consider the weBoost Home Complete for those exceptional circumstances and larger homes.

50 Ohm: The Great Gun

High-quality 50 Ohm cable is the clear winner for commercial installations with cable running over 100 feet and building coverage of 7,500 to 100,000 square feet or more.

Data is the primary application for 50 Ohm cable, and “the internet” makes extensive use of it.Since we want a lot of data from 4G LTE and 5G, this cable is much better for cell phone booster systems. But what is the price to pay?


The connectors on 50-ohm cables are typically larger and thicker. Additionally, because 75 Ohm cables are more common, running 50 Ohm cables may be more challenging if your building is not prewired for them.

When looking for a cellular solution, you should make sure that the cable you choose is either LMR®400 spec cable or higher because there are some 50 Ohm cables that have a higher signal loss than 75-Ohm RG-6 cables.

The 50 Ohm cellular amplifier weBoost for Business Office 100 is our most popular model:

  • Enhances LTE, 5G, and 4G signals on all carriers.
  • Up to 25,000 sq. ft of inclusion
  • Up to +72 dB gain, with up to 24 dBm uplink and 12 dBm downlink
  • Works with all cell gadgets across all transporters
  • Extraordinary for country and metropolitan regions.

The design of the 75 Ohm weBoost Home MultiRoom is very similar to that of the 50 Ohm weBoost for Business Office 100, but it is much more powerful. The Office 100 is able to communicate with cell towers farther away and provide a large coverage area thanks to its 24 dBm uplink, 12 dBm downlink, and uplink gain of up to +72 dBm—the maximum that is permitted by the FCC. It is intended to improve cell coverage within small businesses as a pro-grade unit, but don’t let the name fool you. The Workplace 100 is additionally ideally suited for huge homes that need something more vigorous.

The amplifier is powerful enough to provide superior reception inside commercial buildings and homes up to 25,000 square feet with the right antennas, a strong signal from the outside, and no interference from the inside. However, coverage may be significantly reduced in areas with poor outside signals and other factors like internal building material and layout. Customers with a good outside signal (three to four bars) may receive up to 15,000 square feet, while those in areas with a poor outside signal (one to two bars) may receive up to 7,500 square feet.

Since the majority of large homes and small businesses in the United States are less than 25,000 square feet, the Office 100 is an excellent and reasonably priced option for both types of properties. Additionally, if 75 Ohms is more suitable for your home or office, it is also available.

So what do I want: 50 or 75 Ohm?

Choose 75 Ohm if:

  • The cable run is under 50 ft.
  • Home coverage is under 5,000 sq. ft.
  • House is pre-wired with F-connectors.
  • The best solution for most homes & small buildings.

Choose 50x Ohm if:

  • The cable run is over 100 ft.
  • Building coverage ranges from 7,500 to 100,000 sq. ft.
  • Want the absolute best in terms of power.
  • Best solution for buildings and commercial spaces.

If you know about dB gain, 75 Ohm can lose as much as -1.1 dB per 100 feet of cable compared to 50 Ohm. In essence, 50 Ohm is roughly 1.3 times more powerful than 75 Ohm for maintaining a signal from the same source at 100 feet of cable.
