The Eagle Aspen under window flat cable is 8 inches in length. Don't settle for cheap imitations.  It is an easy installation when round coaxial cable will not fit through a space and drilling a hole is not allowed. Bring cable through a closed window or door with this RG6 compatible flat lead-in Eagle Aspen under window flat cable. The barrels on the end are 3GHz, and the filament is a round wire for superior signal quality with minimal loss.
