LMR 240-75 vs RG6: Which Coaxial Cable is Better for Your Project?

When it comes to choosing the right coaxial cable for your project, there are many factors to consider such as signal loss, frequency range, and power handling capabilities. In this article, we’ll compare two popular coaxial cables – LMR 240-75 and RG6 – to help you decide which one is better suited for your needs.

LMR 240-75 Cable

LMR 240-75 is a flexible, low-loss coaxial cable that operates up to 3 GHz. It has a solid copper center conductor and a foam polyethylene dielectric that provides excellent electrical performance. The outer jacket is made of UV-resistant polyethylene that makes it suitable for outdoor use.

Here are some key specifications of LMR 240-75:

• Impedance: 75 ohms
• Attenuation at 100 MHz: 4.4 dB/100 ft
• Attenuation at 1 GHz: 8.5 dB/100 ft
• Attenuation at 2 GHz: 12.1 dB/100 ft
• Attenuation at 3 GHz: 14.5 dB/100 ft
• Maximum power handling: 1.4 kW at 30 MHz

RG6 Cable

RG6 is a coaxial cable that is commonly used for cable television (CATV) and satellite television (SATV) installations. It has a copper-clad steel center conductor and a foam polyethylene dielectric. The outer jacket is made of PVC or other plastic materials.

Here are some key specifications of RG6:

• Impedance: 75 ohms
• Attenuation at 100 MHz: 6.6 dB/100 ft
• Attenuation at 1 GHz: 16.3 dB/100 ft
• Attenuation at 2 GHz: 23.3 dB/100 ft
• Attenuation at 3 GHz: 28.1 dB/100 ft
• Maximum power handling: 0.67 kW at 30 MHz

 

LMR 240-75 vs RG6: Comparison Table

Specification	LMR 240-75	RG6
Impedance	75 ohms	75 ohms
Attenuation at 100 MHz	4.4 dB/100 ft	6.6 dB/100 ft
Attenuation at 1 GHz	8.5 dB/100 ft	16.3 dB/100 ft
Attenuation at 2 GHz	12.1 dB/100 ft	23.3 dB/100 ft
Attenuation at 3 GHz	14.5 dB/100 ft	28.1 dB/100 ft
Max Power Handling	1.4 kW at 30 MHz	0.67 kW at 30 MHz

 

LMR 240-75 vs RG6: Which is Better?

When it comes to attenuation, the LMR 240 75 has a lower signal loss compared to RG6. LMR 240 75 has an attenuation of 6.9 dB/100ft at 1000 MHz while RG6 has an attenuation of 10.1 dB/100ft at the same frequency. This means that LMR 240 75 can transmit signals with less signal loss than RG6, making it a better option for long-distance signal transmissions.

In terms of power handling, LMR 240 75 can handle a maximum power of 3.3 kW at 30 MHz and 1.1 kW at 1 GHz, while RG6 can handle a maximum power of 1.6 kW at 30 MHz and 0.3 kW at 1 GHz. This means that LMR 240 75 can handle more power, making it a better option for high-power applications.

When it comes to cost, RG6 is generally more affordable compared to LMR 240 75. However, the price difference may vary depending on the manufacturer and supplier.

In conclusion, LMR 240 75 can be a better drop-in replacement for RG6, especially for applications that require long-distance signal transmissions and high-power handling. While it may be slightly more expensive than RG6, the benefits it offers in terms of signal loss and power handling make it a worthwhile investment.
