What is Reddit's opinion of Dual Wi-fi Antenna Kit 5Dbi RP-SMA Antennas and 20cm/8" U.fl/IPEX to RP-SMA Cables?

From 3.5 billion Reddit comments

The antennae are parallel to one another, and the router is roughly 20 feet away from the computer. These are the antennae connected to the 7260 wireless card: http://www.amazon.com/gp/product/B00A4I3AGE?psc=1&redirect=true&ref_=oh_aui_search_detailpage

Yep. You're looking for RP-SMA cables. Like this.

I recently bought this mobo for my brother for a HTPC build, anyone know if I can replace the long cable wifi antenna with a regular antenna like this?

Just get some RP-SMA antennas. It'll probably end up being cheaper, not to mention easier. Here's an example: http://www.amazon.com/Wi-fi-Antenna-RP-SMA-Antennas-Cables/dp/B00A4I3AGE
