Not interest in saving my brain, but in extending my 3G and 4G range.
I'm a little interested as well. For $50, it had better give great reception.
I heard my friend talk about this today. I hope it works.

I have used them from Wilson Electronics with great results...Don't know about these
Hold the (cell)phone - that one doesn't cover the LTE frequencies. Here's a nice indoor one that covers 700 MHz.

I would like to see how they are attached to the Thunderbolt. (It says direct connect). There is no illustration of the antenna connection to the phone.

I would think that it plus into that jack on the bottom back of the TBolt.
Looks to have a rubber plug in it now.
I thought that was covering a screw
Has anyone tried either of these or any other similar device? I recently moved and now my signal has gone to hell (I'm lucky if I get one bar), so I'm seriously considering one of these.
Any reviews/feedback?

thats what ive heard.
i also would like to see how this thing connects..
Are we still unaware as to how this connects to the phone? All we've got is our USB port and our headphone jack... unless there's a secret antennae jack that I'm unaware of?

I know on the droid and several other phones, there are little Antenna diversity jacks so that you can plug in extended or high-gain antennas (usually underneath the battery covers). I have seen the metal connectors (but not in a standardized form) on the inside of the case that connect to the antenna leads inside the back cover. You could potentially solder some leads from those to a proper antenna connecter that you mount on the back of the phone or inside one of those rubber fitted screw-holes. Then you could plug in and unplug your external antenna. As far as standardized connectors for external antennas, I don't think the T-Bolt has one.
emailed that site. heres what they said:
The is a small plastic cover, about 1/4" in diameter, on the back
of the phone. You may remove, very carefully, with a needle, and
the antenna port will be exposed.
Notice, however, that we recommend using the ExtAntPro™ adapter
with the Thunderbolt, because of the very small antenna port. The
regular adapter, which comes with the antennas, falls off very
easily, although it does still work.

they seem to think that cover isnt hiding just a screw, even tho htc says its just a screw. i feel that htc rep might be wrong tho. i might just have to tear my cover off to figure it out once and for all.
edit: ok that htc person is stupid. ITS AN ANTENNA PORT FOR SURE. watch this vid:
http://youtu.be/zdPiT82gWKw?hd=1&t=2m48s pause at about 2:52. youll see its clearly an antenna port with contacts in the circuit board running from it.

Hello, I second that. I had these antennas for a couple years. I never found the antenna connection on the last couple phones I had, so I never even cared to pull the rubber plug, but it is indeed the antenna plug, these antennas work great, special during long drives, or for when I visit relatives who live in the woods, with a very weak signal. Thanks!
nope not covering a screw i double checked
I would never hook up an external antenna to a phone again. I did it once with my old Samsung Epix, and while it improved the signal when I disconnected the antenna I lost all service, so my phone was basically useless after connecting it.
What about a signal repeater, my office uses them and they work great! our corp office is outside of town so weak signal. Get to work and go inside you get full bars - kinda weird when you notice it. They are place on windows on every floor look just like the external antenna but only have a power cord coming off it.

We have one of these at my work as well. Great signal outside, but not so much in the basement of the building. As soon as we moved into that building, getting one of these installed was a top priority of mine. It made a HUGE difference, although mostly for non-VZW!
external antenna
Search U.FL on wikipedia
That appears to be the connector under the rubber plug on a thunderbolt.
I cant find any that just go straight except ipx connectors at rfconnector.com
Does connecting an external antenna affect the internal one at all?

What's the three "pins", dots or whatever you want to call it on the right side of the phone, what does it do? Is it like a dock station or something?
They are supposed to be used in conjunction with a car dock or desk dock to leave the end of the phone open (Think about our phones in a dock, sideways, in your car being plugged into the charging port) the problem is, is that Samsung doesn't see enough customer want and therefor is not currently planning on making said accessories.

Could have something to do with the extortionate prices they wanted for them.
£49.99 for a dock? I expect at least a spare charger to come with it. However, this was not to be the case.

If it makes you feel better, the US version for Verizon is $49.99 but doesn't use said connectors, it's just a piece of cheap plastic with holes for cables.

That sucks. Wanted to buy both.
I was just wondering if I could ask a potentially naive but somewhat related question.
How do the three pins work? I'm assuming you'd need to use two for charging (+ve and -ve)? How do get everything else through just one pin? Have I got the wrong end of the stick?
Thanks, Rowan.
They would sell so many more accessories if they didn't try and pork people do bad.

This has already been done for the EVO 4g using Palm Touchstone capable scraps but I want to take it to another level. Since i'm not much of a programmer I can add to the community in this way.
Please let me know how many of you are interested in this. I'm going to put up full walk throughs as I move along but I will also sell some off (in the marketplace) for those that don't want to go through the hassle. I'm going to start ordering parts and building mock-ups and doing some design work during slow downs at work. I'll have a donation link up eventually if any one wants to help cover the initial costs.
-----------------------------------------------------------------------------
CURRENT DEVELOPMENT STAGE: 1- INDUCTIVE CASE RESEARCH, see #1
PLEASE KEEP AN EYE ON THIS POST (general updates) AND POST#3 (useful links and eventually tutorial)
:good:KEEP DISCUSSION AROUND THE FOLLOWING DESIGN INTENTIONS/ ABOVE DEVELOPMENT STAGE:good:
Design Intents are as follows:
1) A case for housing the inductive coil/wiring
This just requires compatible cases with necessary clearance for the inductive coil and wiring to the male micro usb. Cases with oversized bumpers would be best since they will keep drops from damaging the micro usb plug that will be sticking out of the bottom of the phone. This may not be ideal so if anyone is decent and making plastic molds maybe we could come up with an attachment to a case.
2)NO Hard wiring inside/to the phone
This involves using low profile male mirco USB type B connectors, like this, and mounting and wiring to the case. This will keep your plug always covered and keep you from trying to charge your phone with both inductive and regular usb to the wall/pc. The main design issue here is protecting the male connector to the phone. Suggest usb connectors, wiring, how to boost the amperage, does the palm pre coil protect from over voltage, etc.
3)A car kit.
I will start with my car, A nissan sentra SR, for the car kit. Others are encouraged to come up/share your solutions as well! This should be a hard wired solution using the palm pre/pixi round touchstone dock. Kind of like a dash mount. I think the magnet should hold the phone ok being that my car isn't one of the most powerful things on the planet but for you hot rodders out there keep that possible issue in mind.
----------------------------------------------------------------------------
----------------------------------------------------------------------------
Current Progress: CASEAlright I have the cases in hand! I got three of them in the mail and will be tearing these apart this weekend. The pucks (touchstone bases) should be here sometime next week.
I'm also looking at the following cases
Ballistic
Ballistic 2
Clear S Case
The ballistic I am hoping will give clearance for the micro usb. They will be a bit heavier though... we'll see.
I going to order 2 cases for starters, what should they be?

Regarding the thread, this would be hardware development which i believe belongs in the general section. As for the idea, it seems like as long as its not too bulky most users wouldn't mind if it extended battery life substantially like 24 hours or more. Could make you rich with over 9.million sgsIII owners. But Im pretty sure there are already many types of chargers on the market so unless i missed something perhaps you should submit this to a patent office so no one steals the idea or design. Just my two cents dinner no one else has posted. But ya not software development so I would move three thread before you get flamed too bad.

Just a thought.
What would be the charging time using touchstone/conductive charging; or in other words, what would be the output voltage/current provided to the phone. It takes a while on regular chargers to charge the phone compared to HTC phones.
haha I actually did this too my I500. Literally car kit and everything. Even had it play music through Bluetooth. except I hated cases on that phone so I hardwired it. looked so much sexier. But the case is easier. Built like that too just didn't have the car cradle

I have ordered some parts which should be here late next week. I am still trying to find a source for some type B micro USB plugs. Guess I'll shoud stop throwing away those electronic component magazines. I did a quick search and found some but they were $6.50 each with $10 shipping. If any of you have a source for these let me know. Hell you can send me spare cables and I'll deconstruct them if I have to, but that's not very fun.

Lets do it!
I actually got the touchstone and pre back and ripped out the inductive charging circuit just for this (I actually got it for my evo, but I upgraded before I had the chance to follow the evo guide). I'm excited for this!
Anyway - some heads up - the E4GT is MUCH heavier and bigger than the pre. Don't expect it to stay firmly attached. It will stay okay, but you need a really thin back face of the case. You may also try replacing the thin magnets with thicker rare earths. I actually got it under the stock cover okay, and that worked decently, but no good way to attach it. That's where I quit (after thinking about soldering to the board, but not having a good place on the USB connector without taking the phone all of the way apart. I also didn't fins another point on the board to solder to (like the charging circuit), although I'm sure it's there somewhere.
Also, you need to mount the inductive charging circuit a little low because the phone is so long that it will hit the table and not mount properly if you put it in the middle. Furthermore, be ware that if you add a connector to the USB port, this will exacerbate this problem, perhaps to the point of requiring landscape or stronger magnets.
The USB connector you want are available at a number of places. Ebay has some cheap micro usb adapters (including right angle) that you might play with. If you just want the connector itself, it will likely be more expensive, but I suggest checking mouser or digikey.
Good luck! This will be AWESOME!

I would love if there is an option to somehow add an antenna externally, but not through the use of a microSD card if possible. Does anyone have any suggestions? Thanks!
Doubt it. NFC isn't just a matter of adding an antenna afaik.

I assumed the rest of the required hardware is built into the phone and just the antenna in the battery, but then again the antenna probably needs to receive power so I can see how that would be an issue. Thanks for your input.

Actually on the SGS3 the NFC antenna is in the battery, not the phone.
Sent from my Transformer using Tapatalk 2
Actually I knew that since it was stated in the first post. I consider that still inside the phone.
I thought the user I answered to imagined something like this here as an nfc antenna.
While technically yes, you could make an antenna out of say aluminium foil if you could figure how to cut it so you end up with a tuned antenna, then connect it to the correct pin on the battery connector, I think any sane person would just stick an NFC battery in.
I think they put the antenna in the battery because it's up close to the back of the case. That would also keep it well away from the other antennas that I doubt would like the power pulses that NFC puts out while it's polling.
Oh and Damastus, that picture it hilarious.
I've done the wireless charging mod using Palm Pixi guts. That thin coil of wire is enough to break NFC communication, depending on where it's put. NFC has a VERY short range, so I'm sure it's in the battery to put it as close to potential NFC chips you want to read, and to minimize anything else getting between the antenna & chip (like cases, batteries, etc.)

On the Nexus S, the antenna is built into the phone's backplate.
In theory, you could buy a Nexus S back, remove that antenna, and put it on the inside of your phone.
Run fine wires from the phone's NFC antenna connections to the antenna, and it might just work.
I'd expect reception to be lousy, since you'll detune the antenna by trying to connect it. This also assumes that the NFC circuitry is in the phone, and the battery has only the antenna.

I think you're right, however I'm pretty sure that's what the extra two pins under the battery are for. These pins are only on the Verizon version of the GS3 though, so it wouldn't work for my T-Mobile GS3. Thanks for the suggestion though.
buy a cheapy chinese battery that has NFC and "have at it"
As far as I have known, there is a type of NFC antenna available in the market that can be stuck to the back cover of your Galaxy S3. In this way, you can take full advantages of NFC functions of the Samsung mobile with an alternative mobile battery. However, it seems that most providers like Sunshine Good Electronics Company only do wholesales business on platforms like Globe Resources. You can search it on e-bay, maybe you will be surprised to find on retail seller.
Hi,
I received this phone a few days ago and I am still disappointed that is does not have wireless charging although the back is glass and not metal. I wonder if anyone has tried a hardware mod with something like this. I also saw that there are some external solutions utilising the charging port but I would very much prefer to have that uncovered and I imagine that the linked circuit is way smaller.
I would try it out if no one else did it before if there's a chance of success, so the main question is if there's enough room inside the case and if these three connectors are compatible in general, soldering is no problem if necessary.

Hi, were you successful in any way?
I didn't continue to investigate because I think there might not be enough room behind the battery for the coils. Also getting the connection to the battery/phone right could be really tricky because everything is so small.
