External Antena for mobo

[cTurtle98]

My router is getting really old (manufactured 2006) so I need a new one

my servers are also really old so I thought I would build a new server

 

I am building a server with dual ethernet and wifi so that I can have one ethernet port be WAN (connected to modem) and one be lan and then also have wireless lan

my only problem is that this computer will be tucked away in a cabinet with fans on the back for ventilation.

the motherboard only comes with antenas that screw directly onto the motherboard.

 

any recomendations on an external antena to use? 

i need about a 4 foot cable on the antena so it can sit on top of the cabinet while the computer is inside

Found this 2,4GHz antenna:

And a bit more expensive but the only 5GHz antenna i found with a base on newegg is this dualband antenna but didn't have any specs for the cable length:

depends on how far you need your signal to go.  Can always build or find a cheap Yagi.

I am building this computer to replace my router so it needs to be omnidirectional, yagi is highly directional

It wasn't specified, but you can get a lot of distance from it.  How far are you trying to transmit.  you can probably get away with a basic high gain antenna.  Something like an ALFA 5GHz 9dBi would be decent.  Just make sure you get the correct connector.
