Remote Wireless Infrastructure

At RfWeL we offer both standard stock and custom built low loss and ultra low loss cables for your signal transmission needs. For RF installations requiring coaxial cables, it is usually preferrable 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.

100 ft 400-series Low Loss Cable with N-Male to N-Male Connectors

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.

Below is a table showing typical attenuation loss for some common types of coaxial cables:

Consider the following when choosing a Low-Loss/ Ultra Low-Loss Cable:

  • Characteristic impedance (Should match with impedance of other network components).
  • Frequency of application as it determines the attenuation of your signal, the higher the frequency the higher the attenuation.
  • Operational power handling capabilities
  • Voltage Standing Wave Ratio (VSWR)
  • Environmental conditions (Determines the level of cable flexibility, shielding & cladding material etc.)
  • 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)
  • Phase Delay (Time delay for each frequency component)
