All you need is two impedance converters per run, one between the WiFi radio/router and the cable run in your wiring closet, and another between the wall plate and WiFi antenna in another room. RG6 can evidently support 2.4 GHz frequencies out to 210 feet, while LMR-900-DB can support 2.4 GHz out to 1,130 feet. To run WiFi over RG6 cabling, the main issue is attenuation over distance and connector/assembly loss. As for 75Ω RG6 cables, cablecos offering DOCSIS 3.1 plan to reach 1.794 GHz in the near future. Take a look at the 50Ω LMR coaxial cable running between the sector antennas and the base station at virtually any cell site - in the US, those cables support a mix of frequencies that include 1.9 GHz, 2.5 GHz, and with 5G, 5.8 GHz or higher. doesn't preclude its use with higher frequencies. ![]() The fact that RG6 cable is marketed as being "tested to 1 GHz," "tested to 3 GHz," etc. You definitely can use RG6 coaxial cable with WiFi frequencies, provided that you convert the impedance.
