[SOLVED] Are 2.4 GHz and 5ghz antenna interchangeable

[multiversemeep]

Hello, i have a USB 2.4 GHz wifi adapter, and i was wondering, is it possible to switch out the 2.4 GHz antenna for a 5ghz one? Thanks for any help.

An antenna is an antenna, there is no difference regarding the frequency band. Dual band units don't use a different antenna for once band than they do for the other, it's all the same, so you can't change the antenna and have a magically different frequency. The unit is either capable of a specific band and frequency, or it's not.

Why would you want to mismatch the antenna to the radio transmitter on your WiFi adapter? If the 5 GHz antenna's impedance is mismatched to the 2.4 GHz radio's expected impedance it can cause high SWR (Standing Wave Reflected) that can damage the WiFi adapter's radio transmitter circuit.
