WWAN slot antenna question.

Will the WWAN antennas in the Dell 1420 work with a WLAN card?

I ask because I was going to put 2 wireless cards in my system. One for A/B/G/N and one for better battery life and range using the Atheros chipset.

I have been doing some looking and all EV-DO cards on Dell's site say they support 50 ohm antennas and I have found like 15 external antennas made for A/B/G/N networks that all say they have 50 ohm impedance. I don't know anything about antennas and such but the pictures I have seen of the Dell 1420 have a Grey and White wire going to the WWAN slot and a Black, Grey and White going to the WLAN slot so I am thinking that the Grey and White wires are just split and go to the same antenna in the panel. It seems less likely that there is 5 antennas total in the LCD panel but maybe I'm wrong about that part.

 

They are at fairly different frequencies. I believe WWAN antennas are at 800 Mhz and Wlan is at 2.4 Ghz. Actually there is a harmonice relationship between 800 and 2400 Mhz. You might try it and see what you think.

 

i opened up my 1520 and saw there are 3 sets of wires. It looks like you could have all 3 slots full and separate wires for each component. I dont know anything about the antennas themselves tho.
