Description
RG11 TV aerial coaxial cable with messenger is a type of coaxial cable that is commonly used for transmitting television signals. The “RG” in the name stands for “radio guide,” and the number “11” refers to the cable’s diameter and impedance. The messenger in the cable is a steel wire that runs along the length of the cable and provides additional support and strength. This makes the TV aerial cable suitable for outdoor use, as it can be securely attached to a mast or other mounting structure.
