What type of coaxial drop cable should be used for underground service drop installations?

For underground service drop installations, the ideal choice is the non-messengered flooded coaxial drop cable. This type of cable is specifically designed to be resistant to moisture, which is crucial for underground applications where water exposure is a significant risk. The flooded feature indicates that the cable is filled with a water-blocking gel or foam to prevent water ingress, ensuring the integrity of the signal and the longevity of the installation.

Moreover, non-messengered cables do not include an internal support wire (the messenger) that could be susceptible to corrosion when buried underground. Therefore, they can be direct buried more safely without the additional risk posed by a support wire.

In contrast, messengered coaxial cables are typically used in aerial installations where they need additional support from a messenger wire, which is not necessary or practical for underground installations. Standard coaxial cables lack the flooding for moisture protection and would be unsuitable for prolonged exposure to damp conditions. Fiber optic drop cables, while excellent for data transmission, do not meet the specific requirements for coaxial installations, particularly in scenarios typically covered by coaxial drop cables.
