My task: I need to put a directional wi-fi antenna on the roof of my house to catch a wi-fi signal coming from a few miles and run an ethernet cable for 30 meter from the router to my computer downstairs.
Would the length of that cable (30 meters) impact the speed of my internet connection or will it have no effect?
I was told that it would be better to get the antenna on the roof, place the wi-fi router closer to it and then run an ethernet cable downstairs for the 30 meters distance instead of placing the wi-fi router directly downstairs because the RF signal from the antenna to the router would be highly attenuated if the cable is too long...
Any recommendations? I am also wondering about what Wi-Fi antenna I need to purchase.
I have a trivial question: what is the difference between RF coaxial and CAT5 ethernet cable?
I know wi-fi is radio signal that can have 2.4 GHz or 5 GHz frequency. That is the frequency of the electromagnetic wave.
I guess the signal on the RF cable is an electrical signal at the same frequency (2.4 Ghz)....?
