Coax Cable/Ladder Line Specifications

Type Specifications Image
RG213 A low loss cable with a non-contaminating jacket
Impedance: 50 ohms Power Handling: 1800 watts 30 MHz and less
Attenuation: 1.2 dB per 100 ft at 30 MHz and less
RG214 A low loss cable with double braid and non-contaminating jacket
Impedance: 50 ohms Power Handling: 1800 watts 30 MHz and less
Attenuation: 1.2 dB per 100 ft at 30 MHz and less
LMR400 This coax cable provides excellent performance for high power HF needs or VHF/UHF applications. Because of its solid center conductor, it is rather stiff -- but there is a more flexible version, it's called LMR-400 Ultra-flex.
Impedance: 50 ohms Power Handling: 2100 watts 30 MHz and less
Attenuation: 0.7 dB per 100 ft at 30 MHz and less
9913 This coax cable provides excellent performance for high power HF needs or VHF/UHF applications. Because of its solid center conductor, it is rather stiff
Impedance: 50 ohms Power Handling: 2200 watts 30 MHz and less
Attenuation: 0.8 dB per 100 ft at 30 MHz and less
RG8X A very flexible cable suitable for HF transmit applications where an amplifier is not used.
Impedance: 50 ohms
Attenuation: 2.0 dB per 100 ft at 30 MHz and less
RG58U This economically priced coax cable is suitable for HF applications where high power and long runs are not required. 
Impedance: 50 ohms
Attenuation: 2.5 dB per 100 ft at 30 MHz and less
Ladder Line There are three common versions of this 450 ohm 'windowed' line: 18 AWG, solid copper-clad steel (30%) conductors, poly-clad; 16 AWG, 19 strand copper-clad steel conductors, poly-clad and 18 AWG, 16 strand copper-clad steel conductors, poly-clad.
Impedance: 450 ohms Power Handling: 1500 watts at 30 MHz and less for the 18 AWG and the 16 AWG variety
Attenuation: NA
