Hi all - I have a Realtek RTL8187 network adapter, which has a short RP-SMA cable on the input, and a short USB cable on the output. I need to extend one or both of these cables to a total of 15' or so. Is one more desirable than the other for extending? Or is it better to split the distance & extend both cables? What's the maximum distance I can go in any case? Thank you!
