I am not sure I understand. . .
The RG8U cable from a WiFi antenna carries radio signals, and must be connected to an external antenna connection on a router.
Guess it would help to explain that all of my routers have connections
only for CAT5-6.
Is there a router with a connection or plug for RG8U?
Also thought it would be more affordable to run CAT5-6 for any distance
seeing as how the RG8U coming off of the antenna is only 3 ft long.
