[G1 Q&A, Help & Troubleshooting] jsp254:
I have ****ty tmockery service here. Of our 5 family phones, only my wife and I (G1's) have relatively decent service. I modded ours as listed below. My children's phones, samsung gravity's, have horendous service! They have to walk around to find a spot. All of this is at home... we live in a low spot. There is no chance of us ever getting 3G in this area.

Our G1's used to have the same issues as theirs. I modded our G1 antennaes with psuedo- tesla coils and doubled our coverage! I'm using the xda app right now and can't take or post photos of it, but it works. I'm also running the lasest radio. 23.02 I think..

We live in a brick home. Before, I would have to walk to the far left vorner of our backyard or the frontyard near the road to get enough service to make a call without losing service. I'm sitting in the bathroom right now and have 4 bars! Used to be that I would get one or none right here!

I'll give you basic instructions and will post pics later. I take NO responsibility if this burn, breaks or melts your device. Only do this on phones that have no warranty or the warranty has been voided! IE. I have a bronze and replaced the silver keys with black ones! This will void any warranty you have!!!

Remove back, batt, and sim. Take a wire, your choice of size, and remove the insulation. Sepparate all the strands. Choose one strand. Remember, the thicker the strand, the harder time you'll have keeping your back on the phone. There's very little clearance in there. On the back of your phone, the radio antenna is on the right side. Same side as your volume button. On the lower end of it, remove some of the paint/sealant. 4mm x 4mm maybe... enough to solder on. Set your wire end on this spot. Lay the wire down the phone's back. You will need this to be inside the flat area and not on the curved slope. When you get to the same spot on the bottom, make a sharp turn left. Go close to the sim card area and make it turn up. Near the battery are turn it right. Once you get near the wire again, turn it down. Stay about 2mm away from the wires original path. Continue these turns until you run out of room. In the end, you'll have a wire that spirals to its center in a box fashion. Lay the wire back on the phone and press out any imperfections. Next, solder the begining end of the wire to the spot on the phones antenna. Use caution when soldering! Practice on something before trying this! The phones antenna is held in place by small tips of the plastic going though it and melted down. If you get the original antenna too hot, you will mess up these little tips. Solder the wire with as little solder as possible. Make sure the wire is as flat as it can be with the antenna and is making good contact! Now, make sure the wire is as flat as possible on the plastic. Put a couple of dots of superglue on the length of wire down to the corner. Let these set, holding the wire in place. Don't let your finger become attached to the glue. Use only enough for it to make contact and stick! With superglue, less is best! After this length dries, start glueing each corner of the coil, not letting any part of the wire touch itself. Maintain the sepparation down to the center. After it's dried, you will need to file down the solder to make sure your back will fit. If you can't get the cover to fit, you may need to scratch some grooves into your back cover. When you set the back on the phone, it may make slight indention in the plastic where the wire is pressing against it. If not, maybe use a little chalk to outline the wire and then put the back on. The point being to transfer a line to the back where the grooves need to be made. The plastic of the back is not verry thick! Use caution or you could go through the back! You should see significant gains in signal strength. Mine has been modded for close to a year now. No problems so far.

Pics later today.
