    Ok, will fill that in later. I have spare white and black wires from another laptop that I was going to use. Both wires are coaxial style so does that mean that I can just make two of those aerials shown in the vid and put them side by side, would that work? I don't have time now, but when I do, I will fill in the system specs, thank you very much for your help, much appreciated!

    P.S. Am trying to rep you but it won't allow me, apparently I need to spread it round or something, some lucky people are getting random rep!

    Maybe I didnt make myself clear. I just need help to check to see if I just make two of those antennas, one for the black, one for the white. Is that right? Hope you can help and as before, thanks very much for your help.

    No. you just make one.
    If you stop the slide show at 0:37 it tells you what ends of the antenna get soldered to the center wire or the shielding on the coax cable.

    You will need a two wire to coax cable transformer, and a way to connect the wires to the transformer, plus all the other parts shown in the slideshow.

    Right, now I am really confused! Thank you so much for replying and all that info! I understand that where to solder the wires but I have two cables coming of the wifi card, I know these go to antennas and I know the white is the main and the black is the aux but I don't know what that means! what do you mean by a way to connect wires to the transformer? And finally, from the wiki pages you posted, I understand that the wires have to be a certain distance apart, is that true? Thank you very much for replying, much appreciated! Sorry this reply was late, i am in the UK so was fast asleep when you posted! I am trying to plus rep you but it is quite hard!

    They can be different, but in your case "White the main" means that it is the lead that is "hot", and should be connected to the copper center lead of the coax. "Black the aux" is the ground, and should be connected to the braided silver shielding of the coax.

    Don't be too concerned about hot, and ground. The voltages are so low, they won't present a problem if you touch them, and they shouldn't cause a problem with the card either because all your dealing with is the signal strength, although there are exceptions.

    A directional antenna transmitter with a sufficient amount of signal power can fry equipment if it is aimed at the equipment's antenna.

    Music Guy123 said:

    If you are going to use coax, the coax connector will thread onto the transformer, and you need a way to make a reliable connection from the two wire lead of the wi-fi card to the two wire lead of the transformer. Male/Female spade connectors should work, and will allow you to change them.
    It will also allow you to swap them around to see if you get better reception.

    Yes in the case of the twin lead. This is already built-in by the manufacturer.
    Twin-lead is constructed of two multistranded copper or copperclad steel wires, held a precise distance apart by a plastic (usually polyethylene) ribbon. The uniform spacing of the wires is the key to the cable's function as a parallel transmission line; any abrupt changes in spacing would reflect radio frequency power back toward the source. The plastic also covers and insulates the wires.

    It won't affect the white, and black wi-fi wires or the coax.

    Your welcome!

    Do not worry about the time or the rep. The time difference is an inherent "nature of the beast" when dealing with posting on a forum.

    And, rep is rep. You can't come back to me until after you've rep-ed at least 15 other members.
    Try to relax, and enjoy your project.

    Please! I would like to see your System Specs!

    Well, what can I say but thank you! It is almost explained, I guess what you mean by frying the card is if I go right up to a router or with in 10m of it and stick the antenna pointing at it? My reason for this is because I like to work outside and I can't get internet, hopefully I could use this. I am still confused about one thing though, the wires have two copper connections to the card, does this mean that each wire has to cables in it (probably in a coaxial style?)? I think you have seen the connectors, they have two copper connectors. Just hope you can clear this up for me! I also did my system specs! Thank you so much again!

    If you mean the antenna you are trying to build no, it is only used as a receiver not a transmitter.

    If you mean something industrial like a television or radio tower then yes.
    You have to have a generator, amplifiers, and RF equipment to transmit the amplified signal.
    Again, yours is only used as a receiver not a transmitter.

    I remember years ago when we were young, and dumb, crazy Eddie a friend of mine climbed a television tower that also had Microwave repeaters/transmitters on it to get a look at the view.
    Within a few days he wasn't acting right, and his parents took him to the doctors.

    They found out his brain waves weren't right, and he was slow from that time on. His body apparently intercepted some of the frequencies. Its why we called him crazy Eddie.

    Do you see my underline in your quote?

    No, each one of the wires, white, and black have only one conductor usually stranded copper.


    Thank you for the specs. It will help me in looking for you.


    I gotta go, will check back around 9, 10pm your time.

    Yes I did mean two! I didn't realise each wire had only one wire inside it, I thought there were two as I only looked at the connectors. This makes a lot more sense now! Thank you so, so much! Is that story of your Eddie actually true? Also, I know this isn't the right place to post this but I have picked up a 52 in 1 mem card reader for £2! Bargain! The only problem was that the connector is one of those 9 port usb internal headers. Is there any way to possibly convert this to a standard male usb plug? This is what the connector looks like: Redirect Notice

    I want to just connect it to a standard usb male plug. Here is a diagram of the uses of that internal header: Redirect Notice

    I don't know whether this would help but it looks helpful: Redirect Notice

    Yes the story is true.

    Not without some difficulty, it would be easier to get a suitable adapter cable. one that has an male end to match what your pix shows, to a standard male usb plug on the other end.
