Most important beside the pigtail mentioned by kevsh you would need the same - or at least a similar - antenna like TL-ANT2424B on the other side of the link to be able to communicate over long distances. If the link is over a short distance only, you probably can receive weaker signals sent by some other antennas, but to make use of the power and reception sensitivity of TL-ANT2424B it's best to use two of them at each side of the link.
