I have a Sprint note 2 (SPH-L900) and noticed these antenna ports (I think that's what they are) They are covered by a thin plastic layer that looks like I could probably pierce it with something, but I haven't tried it because I am not an idiot. One of them is labeled "R1" and the other "G"
I have heard that unless you buy the right external antenna, that use of these ports can hurt your phone, potentially disabling the internal antenna. That being said, I was looking for an antenna case for the note 2 that will increase my signal, or bring those ports outside the phone so I don't need to remove the battery when using the external antenna (And removing the ext. antenna will still have the internal one enabled.) I looked and searched the fourms, and could not find information on an antenna case for the note 2. If any of you know where I can find one, or possibly customly order one that would be appreciated.
Thanks.

has anyone noticed that when you take the batter cover of the evo there two holes on the right side of the handset that you can see two antenna connections. anyone think maybe you can use these antennas: http://cgi.ebay.com/Tyco-Universal-...-PCI-U-FL-/280359933530?pt=LH_DefaultDomain_0 to boost signal or what are they for?
well, i think what you are referring to is the antenna connectors they use in the factory to test gps/4g/wifi. You would have to find the scematic to discover which one is for the wifi. Even then, since most likely the antennas that wrap around the outside of the back casing are connected to those ports, I am not sure if they would be powerful enough to make a difference in the reception.
But, you have me interested so I am looking around.
They look similur

They look the same as the ones on my netbook internal wireless card thats why I think the antennas would fit. But like you said even they might of been for testing and might not even help and btw if you look closley thru two vent on the right side on back of evo youll see the connections are open and nothing seems to be connected!
I believe those are test ports. But you could connect an antenna to it, but you would have to make a matching/phasing array for the external antenna to properly couple. Otherwise your impedence will be out of whack, and you will probably get zero reception, as well as possibly damage the transmitter output. Since we are talking very low power you will also have to contend with line loss going to the external antenna. All in all I wouldn't bother.
Yeah I prob wouldnt was just curious if anyone had any ideas.
Anyone ever use one? If so, what do you think of this?

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?

The TB jack is not a Hirose U.FL. It looks more like a MS-156.
I was wondering if i could buy like a small external antenna to put into my dinc. I have the extended battery so I think it will give enough space for a small external antenna. Is there any out there I been googling it, nothing really comes up to what I want to see, haha.
You will not be directly connected to the antenna amplification section of the phone.So it would essentially pointless,But just for s#@ts and giggles,You could make one!!!!! The only jack I would try it on is the 3.5mm minijack!!! Like I said you will not be connected directly to the phones antenna but you may get a phantom effect and you'll also get noise!! I know where your trying to go with this but there's too many variables to get what your looking for! It would be nice though!
lol alright I will just give up on the matter. I just hate not having freaking service anywhere. Do those things that attach to the cars actually increase range?
I believe there is a port for an external antenna under the battery door. It's on the right side at the bottom, right below the battery, there is a circular cap over it.
I think thats some sort of service port . I looked into this a few months ago. Dont remember exactly but I came to the conclusion that there wasn't anything to be done with it.
External antenna mod:
http://androidforums.com/htc-droid-incredible/132850-external-antenna-mod.html
Does anyone know of an external antenna for the GN? Perhaps a backpack style or battery door or even a case that plugs into the external antenna port?
I live in an area where I often have very weak or no signal. I have tried several radios and have similar performance on most of them. So I figure the better fix would be a better antenna.
The part you're looking for is very elusive. People have tried with similar butbwrong parts and borked their phones. Nice thread about it in gs2 forum.
sahibunlimited picks his nose. in his sleep.
From what I've seen here, plugging an external antenna in is a very bad idea.
Don't plug anything into that port. You'll permanently break the internal antenna. Read the thread in sgs2 forum.
Thanks. I'll take a look over there.
Here is the other thread if anyone else will benefit from it.

I guess as of now I will just suffer since I really dont want to goof up the connector. I did destroy the connector on my Vibrant and had to solder bridge it. I used the wrong connector and it got stuck and actually ripped the connector off of the vibrant, so i solder bridged the 2 points on the board before even powering up the phone for fear of blowing out the radio while not having the antenna connected. It worked the same after "removing" the connector so it wasnt a complete loss.
Oh well maybe Ill look into a wilson amp or something similar.
So I've got a SM-P600 32Gb Wifi tablet, and the WIFI has stopped working on it. Already tried factory restore, etc. but nothing helps, so I'm quite sure it's a hardware issue.
I'm not finding any available motherboards or screen broken tablets of the WiFI version available on ebay to replace the board. However there are quite a few 4G model ones available for a good price. Does anyone know if the form factor of the motherboard is the same across both versions? I'm not planning to use the 4G, I just want to know if the board will fit in my tablet assuming I steal it from a smashed up one.
Thanks in advance.

I've never dissected my Note so I couldn't give you pointers. However, you are aware how risky that is.
Taking parts from the boneyard and putting them into your WiFi version won't give it 4G. The devices are fundamentally different.
I have a safer alternative. Use a USB modem in conjunction with OTG.

I'm talking about swapping the whole motherboard because the one that's in there is toast (wifi/bluetooth chip is toast). I could care less about 4G, as I made abundantly clear in my original post. I'm not worried about any "risk" factor, as the device is a brick w/o WiFi. It has no method to access the internet at all.
My question is only if the 4G motherboard will fit in the WiFi case. I'm betting it does as I see an unused connector on the board which I'm guessing connects up to either an antenna or 4G board in the other version. Worst case I can just buy one of the 4G ones with a broken screen and use my screen to replace that screen.
OK, I think I found my answer. Finally managed to find a picture of the 4G board on ebay, and it's identical layout with the exception of a little L-shaped piece that sticks out of the right side. I can see that in the housing there is a place for that little L shape to lay, and off of that I can see where the antenna wire is supposed to lay.
I'm going to buy one of these boards and go for it. Will report back when I definitely confirm it's compatible.
Check whether the display is compatible with both pcbs. This can be determined by checking spare parts ads.
Then there is the missing opening for the sim slot and probably a missing 4G antenna(which may just consist of pcb traces anyway).
OK, I confirmed that the motherboard is definitely compatible and all fits in there perfectly!
I did have to transfer over the little board where the sim card and microSD card go as there was no channel soldered on where the sim card holder belonged. Also had to use the silver rim from the 4G version one so I'd have the little sim card slot.
Other than that was pretty much just swapping the motherboard out and adding in the antenna wire/board. Now I've got a fully functional 4G version (even though I'm only going to be using WiFi).
