Replacement for the Wifi Antenna that comes with mobo?

[jaypro]

My dog chewed up the wire for my antenna and I need a new one.  I don't know enough about this stuff and was wondering if I could get some answers.

 

Info (hopefully relevant):

 

motherboard: asrock z87e-itx (link: http://www.asrock.com/mb/Intel/Z87E-ITX/ )

antenna: ASRock WiFi 2.4/5GHz Antenna

 

 

Questions:

 

When looking at replacement antennas on amazon/newegg/etc, why do they all have 1 wire, but the antenna mobo came with had 2.

2.4ghz vs 5ghz? I need both (2 antennas?)

Why do the prices vary so much? How important is the antennas and what should I be spending my money on for equal/greater performance than the stock antenna?

antenna's are pretty important but i woudnt overspend on them, link a few that you are looking at so we can see if they're good

though i would rather have wires leading to a standalone antenna, i can't find one with 2 cables.

Can you post a picture of the connectors on your motherboard?

Just get a pigtail cable and attatch whatever antenna you want (obviously not a huge one as you dont want to burn out your wifi card).
