RG214 vs RG213 | Product Knockout

RG214 vs RG213 Product KnockoutOur Product Knockout series is a match-up between two similar products. In boxing terms, think same weight class, same caliber, and same level of experience and amount of exposure. The purpose of these posts are for you to see a side-by-side view of two similar products, and to be able to understand which one will be crowned champ for your specific purposes. Take your seats and prepare for battle, because the gloves are coming out.

RG214 and RG213 are coaxial cables used for high-frequency signal transmissions. Both cables are designed for use in telecommunications, radio communications, broadcast, and computer applications. RG214 coax and RG213 coax are very similar to one another, however there are a few defining characteristics that set them apart. Can you guess what they are? Let’s first start by taking a look at each cable’s construction.

RG214 vs RG213 Specs for Construction
RG214 RG213
Conductor Type Stranded Stranded
Conductor Material Silver Coated Copper Bare Copper
Dielectric Diameter 0.285” 0.285”
Shield Double Silver Coated Copper Braid Single Bare Copper Braid
Jacket PVC PVC
Overall Diameter 0.425” 0.405”
Weight 138 lbs/mft 110 lbs/mft

RG214 features a silver coated copper conductor, while RG213 features a bare copper conductor. Although both conductors are stranded, the material is what sets them apart. The silver coated copper material in RG214 coax is more conductive than the bare copper material in RG213 coax. So, this means that RG214 has a smaller signal degradation than RG213. In terms of shielding, RG214 coax offers a double coated braid, whereas RG213 coax has a single bare copper braid. Both the shielding and the conductor material are the reasons for the significant price differences between the two coaxial cables. RG213 costs much less than RG214 because its bare copper conductor and single bare copper shield are much cheaper than the silver coating in RG214.

RG214 vs RG213 Electrical Specs
RG214 RG213
Min. Temperature Rating -40°C -40°C
Max. Temperature Rating 80°C 75°C
Max. Voltage 5,000 5,000
Impedance (ohms) 50 50
Capacitance (pF/ft) 32.2 32.2
Max. Freq. (GHz) 11 11

Looking at the electrical specs, RG214 and RG213 remain pretty consistent across the board. Both cables are able to withstand a high voltage rating of 5000V each, and are the same in terms of impedance, capacitance, and max frequency. The only slight difference between RG214 coax and RG213 coax is the maximum temperature rating. RG214 is rated slightly higher at 80°C, while RG213 is rated for 75°C.

RG214 Loss (Attenuation dB/100ft) RG213 Loss (Attenuation dB/100ft)
50 MHz 1.7 1.2
400 MHz 5.5 4.8

To fully understand coaxial loss, referring back to what was previously mentioned in the cable construction section can help us to make sense of the difference in attenuation. Because RG214 has a stranded silver coated copper conductor, it is easier for an electrical charge to pass through this material than it is for the charge to pass through bare copper. Overall, it seems that most of the differences between the two cables can be attributed to RG214 having a silver coated copper conductor and RG213 having a bare copper conductor.

Winner by unanimous vote? Instead, it seems as if the match has ended in a technical decision. In this case it looks like our crowned champ depends on your specific application use.

If you are unsure about what coaxial cable you’ll need in order to meet the needs of your application, consult with a qualified engineer or with one of Allied’s knowledgeable sales reps. To learn more about RG214 and RG213, visit the coaxial cable main product page.0

    the RF losses of 214 are not higher than 213 – there must be a mistake in the table
