# Cable Diameters

Although standard cable measurements exist, the size may vary compared to what is shown here. It depends on the manufacturer. The unit used is the millimeter.

### Cable Diameter Size: RF Coaxial Cables

For SYV-50-1 the outer diameter of the shield is 1.455. The outer diameter of the jacket is 1.9. For the RG-178/U, the outer shield diameter is 1.375 mm; the outer jacket diameter is 2.01 mm. The SFF-75-1 outer shield diameter is 1.375; the outer jacket is 1.80. For the SYV-50-2-1, the outer shield diameter is 2.15; the outer jacket diameter is 2.9.

The RG-174/U shield diameter is 2.245; the jacket outer diameter is 2.54 mm. The RG-316/U shield diameter measures 2.065 and the jacket diameter is 2.59 mm. The SYV-75-2 outer shield is 2.15 mm and the jacket 2.9 mm.

### Cable Diameter Size: Flexible Cable

The SFT-50-2-1’s outer shield is 2.2 mm in diameter. Its outer diameter is 0.51. For the SFT-75-2, it is also 2.2 mm. The outer diameter is 0.27 mm. The RG-405/U cable’s shield diameter is 2.2.

The outer diameter is 0.51 mm.

The SFT-50-3-1’s diameter is 3.6, with an outer diameter of 0.93. For the SFT-75-3, the outer shield diameter is 3.6. Its outer diameter has been measured at 0.55 mm. It is also the outer shield diameter of the RG-402/U. However, its outer diameter is only 0.92 mm.

For the SFT-50-5.2, the outer shield diameter is 6.0. 1.60 mm is the measurement of its outer diameter. For the SFT-75–5.3, it is 6.0. The outer diameter has been measured at 0.95.

### Cable Diameter Size: Common Corrugated Copper Pipe Cable

**Note:** the diameters here are the crater conductors.

The outer diameter of the RFF 1/4"-50(NK) is 1.9 mm. For the FSJ1-50A it is also 1.9. For the LDF1-50 it is 2.6; for the SYFY-50-7-51, it is 3.1 and for the RFF 3/8"-50(NK), the outer diameter is 2.6 mm.

The outer diameter of the FSJ2-50 is 2.8 mm. For the HLT4-50T cable it is 4.8 and for the RFF 1/2" it is 3.55 mm. The FSJ4-50 measures 3.6; the LDF4-50A is 4.6; the HJ4.5-50, 6.9 and the VXL5-50 cable has an outer diameter of 9.42. The HJ5-50 cable has another diameter of 9.1.

### Cable Diameter Size: Special RF Coaxial Cable

The diameters here are for the crater conductors.

The 1/2"SFX500PE has a diameter of 3.5 while the 1/2"FXL540PE has a diameter of 5. The LMR400 has a crater conductor diameter of 2.74.The RG6-5 has a diameter of 0.9; the RG-11 has a diameter of 2.17 and the LL-335, 2.5 mm. The diameter for the TEFLX-RG401 is 1.6.

For the SUJ-50-7-5 it is 2.6; the Astrolab 32055 has a diameter of 1.5. The LI235 has a diameter of 1.45; the MICOV COAX has a diameter of 1.45. For the RG 223/V, it is 0.89. For the LMR-600, it is 4.47 and the 5D-FB, 1.8.

The cable diameter size will vary for other types. Depending on the setup, the insulator thickness and other factors, the specifications and dimensions of cables may change.
