Modify S200 GPS antenna to improve GPS signal strength

---

as you konw, S200 GPS is not easy to fix, let me tell you a simple method to fix this problem.
1. Turn off your S200, open rear cover, remove the battery, locate the gps antenna position.
refer to f1.jpg

2. Peel the black gps antenna carefully and turn over from left to right. use the multimeter to measure resistance between two electrodes and you'll find it's short-circuit status (~0 Ohms).
Look carefully at the root location of the antenna, there is a black transparent line, at the end of this line,you can find the short-circuit point, cut off this copper chips until the short-circuit point completely disconnected, then measure resistance between two electrodes to determine it is no longer short-circuit (Infinity ∞ Ohms).

refer to f2.jpg d1.jpg and modification diagram.jpg or this (surcart's pic).

recovery the antenna, turn on your S200 and test gps. Enjoy it !

refer to c1 and c2 pics (compare with HTC P3600, left is P3600, right is S200)
c1.jpg is before modify, c2.jpg is after .

btw, tracking speed is faster than before.

d1.jpg is a large pic
d2.jpg is the details after modified


maybe you can do it without peeling antenna off, try to cut the short-circuit position directly if you are not sure you can completely peel off. refer to d2.jpg or s200_p1.jpg(provided by wysxs, thx) or Victor79's pic .

Has someone tried it already?

of course, i‘ve finished this modification and tested, gps now is very fast to track

what do you mean with "confirm it's short-circuit status"?

but if this methode works, this would be great

Well, this would be excellent if it works as gps signal can be a pain in the ass to get on this phone. Can you explain in more detail and maybe a before and after-picture comparison on the removed "copper chips"? One that is more of a close up than the 2nd picture in your guide.
I'd like to know exactly what I'm doing before trying this out.
Thnx.

So can you make a video of this?

Yes a video would be fantastic

sorry for my english,
pls see these two pics (compare with HTC P3600, left is P3600, right is S200)

That's great but can you open your modified s200 and take a picture like the f2.jpg that shows how it should look after you have removed the copper chips ?
We would like a more detailed guide of how to do this.

pls see d1.jpg in the first post for details.
