Coax attenuation figures in dB per 100ft
Be aware that this table is designed to give approximate values for HF, VHF, & UHF use.
Some values that were not available in the original specification details for an entry have been extrapolated using adjacent values and should be close enough for amateur use.
Please add other cables at the bottom of the table as it currently needs hand-sorting (or a trip through LibreOffice Calc)
