This heavily shielded communication wire provides rugged mechanical protection, shielding your system's critical communication links from UV damage, extreme weather, and yard pests. By utilizing the DIYPRO™ cable, you effectively bypass the requirement for running separate electrical conduit between the indoor and outdoor units, which simplifies the physical installation, reduces project material costs, and provides a cleaner, professional-looking finished product.
