Option 1 - All active extenders: Two or three of these would be ideal. http://www.cdrking.com/local/product...076136-2709712

Option 2 - Mixed active and passive extenders: One or two of the above and one or two of these if you want to save a few bucks. http://www.cdrking.com/local/product...902268-9152212

Theoretically, you can have up to 5x 5-meter active extenders (to support devices approx. 25m away) per segment.
