802.11 Super G (108Mb) antenna upgrade...

[tordoffm]

Hi all,

I'm needing to purchase two replacement (bigger and better) antenna's for greater range.
The router I've got supports 802.11 Super G, which has the 108mb transmission rate, as oppose to the 802.11g - the 54mb transmission rate.

both 11g and 11 Super G run at 2.4 Ghz.
Can I use an 11g antenna, and still (theoretically) connect at 108Mb - or does the antenna have a bearing on the negotiated speed?

I only ask, as I have search high and low, and can not find a specific 11 Super G antenna - I can only find 11g antenna's.

Any help/advice appreciated.

It should make no noticable difference. If an aerial is cut to work within a certain band of frequencies, then using B, G or a Super data rate should have no effect, since the channels are pre-determined.

If one was to massively increase the data rate so that a much greater bandwidth was required, i.e. the need to theoretically use additionally say "new" channels 14 to 24, then it is possible that the designed bandwith of the conventional aerial would not allow this. The efficiency of the 2.4GHz aerial falls off quite sharply once it is used outside of the prescribed band limits.

Thanks for the answer - thats a great help.
I'll get hunting for an aerial now then!
