The Coaxial Cable length calculator determines the maximum usable length by considering the signal frequency, the type of cable (RG-6 or LMR-240) and the type of loss (for example, ≤3dB). The cable’s attenuation value at a given frequency is used in the formula which determines how far the signal can be sent without degradation. For improved user experience, online aids have been created which help in selecting the exact RF and video system length requirements.
