Comparing Attenuation Performance: LMR-240, RG-58, and RG-223

When it comes to coaxial cable performance, the attenuation characteristics are crucial, as they directly impact the signal integrity and transmission efficiency. Let’s take a closer look at how the LMR-240 from Times Microwave Systems compares to the more traditional RG-58 and RG-223 cables in terms of attenuation:

 

Frequency	LMR-240 Attenuation (dB/100ft)	RG-58 Attenuation (dB/100ft)	RG-223 Attenuation (dB/100ft)
1 GHz	2.1 [1]	4.9 [2]	3.5 [2]
3 GHz	3.5 [1]	8.1 [2]	6.0 [2]
6 GHz	5.3 [1]	12.0 [2]	9.3 [2]
10 GHz	7.6 [1]	17.5 [2]	14.0 [2]

 

As the table clearly illustrates, the LMR-240 cable offers significantly lower attenuation rates across all the tested frequencies when compared to the RG-58 and RG-223 cables.

At 1 GHz, the LMR-240 has an attenuation of just 2.1 dB/100ft [1], while the RG-58 and RG-223 cables exhibit attenuation levels of 4.9 dB/100ft [2] and 3.5 dB/100ft [2], respectively. This difference becomes even more pronounced at higher frequencies, with the LMR-240 maintaining a clear advantage.

For instance, at 10 GHz, the LMR-240 has an attenuation of 7.6 dB/100ft [1], whereas the RG-58 and RG-223 cables experience much higher attenuation levels of 17.5 dB/100ft [2] and 14.0 dB/100ft [2], respectively.

This superior attenuation performance of the LMR-240 cable is a key factor in its widespread adoption across various industries, where signal integrity and transmission efficiency are of utmost importance, such as in telecommunications, satellite communications, and high-frequency RF systems.

By providing this side-by-side comparison, I aim to highlight the distinct advantages of the LMR-240 coax cables from Times Microwave Systems, positioning them as a preferred choice over the more traditional RG-58 and RG-223 cable options.
