Can you switch antennas on an X220?

I have an X220 with a WWAN card.  I don't use it anymore so I will be switching it out for an MSATA.  I will then have two spare large antennas.  I know that sometimes you want to match antenna size to wavelenght and sometimes you just want a big atenna.  If in wifi, you just want it bigger, well, the WWAN antennas are bigger.  Should I swap the wires so my wifi gets the bigger antennas?

No.

 

You'll gain absolutely nothing by doing so, and might actually end up with worse wireless (802.11) reception...

I tested this. The WWAN antenna produces a slightly weaker signal when used with WiFi card.

Re: Can you switch antennas on an X220?

Good to know that I am not the only one with these crazy ideas.  I assume you wouldn't bother removing the wwan atennas for weight/interfearence?  

 

Do you know if the silver metal tape helps the antenna?  I had to buy a new back case and I wasn't really able to move it over.  If it is part of the antenna, how much is ideal?
