Coaxial Cable Construction and Signal Transmission Characteristics
For RF installations requiring coaxial cables, it is usually preferable that you maintain the attenuation loss as low as possible. Cable runs for RF installations should be maintained as short as possible to ensure minimal signal loss.
Coaxial Cable Construction
Typically, attenuation loss is a factor of cable length and frequency of operation. The longer the cable run, the higher the loss and the higher the frequency of operation the higher the attenuation. It is therefore advisable to use the 400 and 600 series cable for runs greater than 100ft.
Coaxial Cable Roll
Below is a table showing typical attenuation loss for some common types of coaxial cables:
200 Series Coaxial Cable Typical Attenuation in dB

Consider the following when choosing a Low-Loss/ Ultra Low-Loss Cable:
Noise handling (The symmetry of signal and returning current carrying conductors cancels, to first order, all effects of external electromagnetic fields. Any residual susceptibility in a coaxial cable results from imperfections in its shield)
