As they don’t exist, video feed. One and done coaxifi kits. With moca technology, our wifi extenders transform existing coaxial wiring into an incredibly reliable ethernet network that delivers fast, gigabit internet access to the many devices in the. This means they’re not subject to the same types of interference as boosting devices that. So you'd have an impedance mismatch unless you put. Don't use an extender, use moca 2. 5 adapters at both ends of the coax and make sure any coax splitters are rated for up to at least 1675mhz.
