I modified the antenna of my usb bluetooth, the range of the device used to be very small, now the damn thing works almost like my wifi router used to work!
I didn't buy anything for this mod since I already had everything needed, the antenna was taken from my fried dlink router along with its "piggy tail", well that's basically all you need =0)
This mod also requires a bit of soldering skills but nothing fancy
Tools needed:
Soldering iron,solder,super glue and for cosmetics, Patex glue!
These are the pics of my Trendnet bluetooth before and after the antenna modification
Very small range!
Crazy range(before cosmetics), my phone now connects to the pc throughout the whole house... Even if you got 3-4 concrete walls between the 2 devices!
After my cosmetic appliance of Patex to the part of plastic where i cut...
This mod is very simple, you have to desolder the antenna on the bluetooth
The antenna looks like this, its the blue thing with WTC printed on it.
It has 6 connectors, the ones on the right side are not important, they are only there to hold the antenna...
The ones on the left are important.
Carefully desolder the pins, remove the antenna and solder the end of the pig tail in its place, the side of the pig tail
should be soldered to the ground pins and the middle should be soldered to the middle.. very simple...
Once you're done soldering, apply some super glue to the pig tail and at the end of the board (not where you soldered!!!) and stick them together, this will hold the solder when some force is applied to the pigtail, i personally applied super glue then a layer of Patex(i love patex =0P ) this way it's super secure...
Then make a small drill on the cover of the bluetooth where the cable will go out from, close the cover, apply some super glue to close the cover, apply some Patex to where you drilled(once the wire is in it of course...) this will make super sure that the wire won't come out
and no pressure will be applied to the solder point.
Congrats, now you have a super bluetooth!
