Official Antenna Tutorial:

When I finish the complete guide this is what I will be using for the antenna portion. Since I just finished this portion of the project and had a camera on me I decided to take the time to write it now.

The antenna is a critical component of this project because it is tough to sometimes get a satellite lock with the back case on. For those of you who have been following this project the other location for the antenna works but not as well. I would recommend this spot if you are installing this into your system.

Step 0: Please remember where things came from, screws, wires, etc. It will make your life much easier. Not all of my pictures will be able to explain where things are supposed to go back to.

Step 1: Take motherboard and battery completely out of tablet.

After this is done, your table should look like the following. (for some reason my tablet looked a bit different when opened up, but you get the gist)

Step 2: Remove metal bracket

This part is easy, just make sure the cords are out of the way. Just remove approx. 8 screws from the frame and it just lifts right off. Here is a pic of what it should then look like.

Step 3: This is where things get interesting.

At the top of the bottom section there is a screw hole which has to be removed. You can use any method of removal that you want but here is what I did. First take a screwdriver and pry the metal "screw thread" out of the plastic housing around it. Next use a pair of needle nose pliers to pull up as much plastic that was holding the "screw thread" in as possible. To finish it off use a razor blade to cut flush, the rest of where the "screw thread" was located. It's kinda hard to put this in words but pictures should do this justice.

(This is the completed image)

Step 4: Modify metal bracket.

This part is actually pretty easy and may not even be required. I only did it to gain as much space for the antenna to do its job as possible. I would recommend doing this. As you can see in the "before and after" pictures below a tab on the bracket needs to be ground off. This tab was not screwed into my tablet in any such way, so it's not like it mattered. To remove the tab get creative :p . I used a grinding wheel, but I'm sure that you could use a hacksaw or any other method. Take a look at the below pics and you'll understand better :D

Step 5: Put the GPS antenna in.

Put the GPS antenna in the location that you just cleared out. You will have to remove a corner of the foam that is holding the camera down (not really a big deal). Put the chip in and if you choose you can secure an edge using any method of your choosing (just so it doesn't move) I used a tiny piece of sticky tack. Look at a few of the images below to figure out antenna orientation. It is pretty easy to see.

Step 6: Put it back together.

Reverse everything that you just did taking it apart. If you did it properly, you should have an antenna mounted as pictured below. It gets better reception and is probably the best location in the tablet for this antenna.

I hope that this helps out those who are having trouble finding a "good" location for their antennas. Post any questions that you have about this. I would be glad to help you out.
