Dual or single antenna?

[Possum1995]

Need to buy a new WiFi card and antenna for my laptop but found out that I can fit either a dual or single antenna. The dual is clearly not just two single antennas at £1.98 more expensive. Could anyone please advise me on which one I need and also what the difference is?

I cannot guess as to what HP have installed, the antenna goes up behind the display.

So you would look in the WLAN bay and check.

Page 39  lists this....

(6)Antenna (includes wireless antenna cable and transceiver)

Single   854985-001

Dual     854986-001

If it only a single then you need to either use an external dongle, pull a new antenna thru, or just connect what there is installed and hope.

Ok

Yes but my question is what is the difference beetween them. I already know the part codes and have read the manual but would like to know if dual reciever has a stronger signal or something similar.

So the question relates to the WiFi adapter and not really the antenna's.

A single is usually 2.4 GHz.

Dual is 2.4GHz and 5.0 GHz

2.4 is for range, 5.0 is for speed.
