  • 2 WiFi over 1 antenna?

    I intend on installing 2 wireless adapters in my car (running 802.11b/g).

    One will be a modded WRT54GL and the other a normal PCI WiFi card.

    Will I need two seperate antennas for these, or can I split the antenna cable and use it for both adapters? If I can use one only, do I need an amplifier?

    Thanks in advance.

    You can use an isolator/combiner, but it is not worth the cost considering that most cards don't need an antenna, and that WIFI antennas are pretty cheap.

    As for the look, well, you can do it with an isolator/combiner, but the cost is just not worth it.

      I'm dying to know....
      What's the point of multiple WiFi adapters?
      Have you looked in the FAQ yet?
      How about the Wiki?



      Under normal circumstances, a signature would go here.

        The point of two is one is a Kismet Drone and the other is a normal WiFi card so I can run Kismet and Netstumbler at the same time.

          Sorry for the double post, but the forum won't let me edit my other post.

          Anyway, I've decided to put 2 WiFi antennas on top of my car, but I want them to look neat. How close together can I put them? Will putting them with the bases almost touching mess up the signal?

              There is no problem putting them close together, HOWEVER, if one is transmitting it might "wash out" the other antenna if it is receiving. In general, you want at least a wavelength between antennas. Since this is 2 ghz, a wavelength is on the order of about 1.5-2.00 inches.

                I always hoped that as they're microwaves I could warm up a bacon sarnie with them...

                    Sweet. That's the kinda gap I'd have anyways.

                    My DIY housing is gonna be one of a kind. The GPS will not be an antenna, but rather the actual unit. The bottom of the housing will be open for magnetic mounting to car roof (base plate). There will be rubber seals around the edges of the bottom. Please point out any things to change.
