Any simple 5ghz (802.11n) antennas out there?

post #1 of 5
Thread Starter 
I am about to order this motherboard with wifi and happen to think that the provided antenna is hideously ugly (or at least not suited for my build). So what I want is something like this aftermarket antenna.

The only problem is that this model (and most others) are for 2.4ghz (802.11b/g) and I cannot seem to find something like that for 802.11n.

Most modules look like they use 2 identical antennas, but I am uncertain if it is all superficial because of the different frequency.

Any and all help greatly appreciated!

Judging by the picture for the motherboard I would say it is SMA, and that it should work. The extra antenna specifies that it is for SMA, not TNC.

Need somebody to confirm this,
but that antenna is tuned for half wave "Frequency Range: 2.4~2.5GHz V.S.W.R.: 1.75 Antenna Gain: 8 dBi"
so it would be tuned for quarter wave at 5GHz, so should be no problem.

I also don't even know if the motherboard uses the 5ghz band. In fact, the label on the antenna that comes with the board says 2.4ghz. I did check about the SMA vs TNC connectors and the board does use SMA (visual inspection) as Trueg suggested.

I think quakermaas is also correct. The antenna should also be sensitive at double the frequency. (based on what I know about waves being very limited, but the musical interval between 2.4ghz and 5ghz is slightly more than an octave. So would resonant (sensitive) frequencies be close enough?)

That looks like RP-SMA.

An antenna is tuned for a specific frequency, the use of an incorrect antenna will cause a loss in performance.

The motherboard only supports 2.4GHz 802.11n with 20MHz channels. So you can choose from channels 1,6,11 (20MHz) with a maximum down rate of 150Mbps. The connection is SMA.

So the antenna will work. Make sure to buy two since the board has two connections for MiMo.
