I have an AC68u I am using in repeater mode for my shop (30x40 metal building). I have about 50% reduction in speed from router inside shop vs router just outside shop. I was thinking if I could use an SMA cable (I think it's SMA connector or maybe RP-SMA) say 2-3' long on each of the 3 antenna to get the antennas outside shop and leave router inside. Would just drill a hole and run SMA cable through. Would the extension cable work or would there be some signal loss from extra length? Would I need to leave 1 or more antenna inside the shop for signal to devices inside? If so does it matter how many?
