Is there a spot to connect a external antenna like on tytn at the back?
No there is not.

Are you sure?
Its usually hidden somewhere in the battery compartment under a sticker or label or rubber plug. It might even be under the battery its self.
What is very strange i found it in one phone under a lable saying Void if removed...
Very odd considering the plug while not public common use. Is a perfectly viable antenna connection and often used in rigs, car phones and business.
But most phones have them.
Yes, this doesn't.
thnx for the info guys. hmmm this might change my descion to get it. unless it has better reception then i get with my Tytn i wont be able to get reception without it.
This is an issue for me too, as I just found this:
http://www.easydevices.co.uk/products.asp?partno=TCANTENNATPRO&model=
Says it's an external GPS antenna for the HTC Touch Pro...
Or would this work?
http://www.mobilefun.co.uk/product/10939.htm?referer=FR_PROD-PR-P-10939
The first thing is discontinued, obviously because they found out (probably by some angry buyers) that TP DOES NOT have a GPS plug.
The second is a full BT GPS device. Works with any BT enabled computer or PDA (inc. the TP).
GPS Antenna
I was also disappointed that there was no BT antenna available.
I was seaching some GPS antenna maker hoping to find some that could use existing MiniUSB port on TP but it seems the port is unable to support communication with GPS software.
So sad, this would have been a good enhancement to TP if there was MiniUSB GPS antenna maker.
Guys do you know what you are talking about?
I suppose not.
BT or USB are not "generic I do it all" technologies. They work based on specific protocols.
A GPS antenna is usually passive equipment - and even for active ones we mean that something amplifies the received signal.
THAT signal (and in fact the whole antenna), is "stupid". It is the part of the chipset to receive the ELECTRICAL data and make them into usable data.
I am not sure if I am getting through, my English are not the best, but the point is that you are looking in the wrong place for the wrong thing.
Now if you want a real USB or BT GPS that you will use instead of the internal ones, that's a whole different story. This works and actually does it by using the "COM" (serial) support that both USB and BT include.
To make the story more complete though, USB solutions will not work for devices that don't support "USB-host" (i.e. being the host part not the client part of the connection). Most WM don't have this (and yes Diamond and TP also don't). So you are left with BT.
To be honest if you are ready to pay for that premium (and you seem to be, by the links you give), what is your problem if what you connected is a full GPS that "replaces" the internal one or not?
I hope everything is more clear.
I presently use a TyTN II, and have an external aerial as the mount for the device is under a metal dash, so shields the signal...
I therefore need an external receiver for GPS.
Se here: http://freespace.virgin.net/shaw.clan/modifications.html and click on the TomTom hiolder link, although this is with the older QTEC 9100.
Make sense?
For driving with my Garmin in the car i used a Re-Radiating in my Xterra with excellent results.
This is basically the setup I have, although the internal antenna wasn't integrated into the power plug.

Mine is a bit more similar to this so you can control where you mount the internal antenna.

I have yet to test it on the Fuze but will probably do it when I have time this weekend. The change in signal strength is drastic (on the garmin).
Woow insanely expensive!

Please let us know if it works.
The Charge has 4 ports on the back (behind the cover), which look like external antenna ports.
Has anyone tried to plug in antenna's to these ports?
(BE CAREFUL! ) I heard one person say pluggin in an external antenna might sever the tie to the internal antenna.... Any solid info on this?
I gett -98db on my charge, when it decides to connect to 4g, its awesome.... but its only about half the time.
I have till the 6th to return it. (I tried the TB, it gets slightly better internet, could my Charge be a dud? I get about -93)
At work all I care about is getting good internet.
They are antenna connectors. Apparently, they are a proprietary Samsung type that you can purchase an adapter cable to go a common connector at bestselldist.com My post count isn't high enough to post a link yet...
The bottom of page 6 of Anandtech.com's Droid Charge review shows a diagram of the antennas on the charge (but not the ports.)
They mention that the 4G and 3G are handled by separate antennas. 3G and 4G each have diversity. What I don't understand is why there is L1R2 on one port but R1 and L2 get separate ports. I presume the smaller connector on the right labeled "G" is for wifi.
If anybody could enlighten us, that would be great. I noticed some antenna/amp booster products for the Droid Charge, but I would prefer to some real antennas with large coax running to a pigtail to hook right up to the Charge.
by the way: I highly doubt that connecting an antenna will cause a problem. You generally don't want to connect antennas when the radio is on. That could damage the phone, but I'm not an expert. I was always told to never connect or disconnect an antenna when the device is on...

Did you ever find a solution to what you were looking for? I'm interested in doing something like this as well.
External Droid Charge Antenna
I know that those ports on the back of the driod charge have a connector that fits them somewhere, and it seems that I'm not the only one looking. Very curious, isn't it?
The G is ground.
Sent from my Galaxy Tab running MIUI
Please use the Q&A Forum for questions Thanks
Moving to Q&A
so?
Anyone find a definite answer on this?
I would like to revive this thread, as I am in a poor signal area and would like to figure out how to boost my signal properly by plugging in some external antennas.
I am looking to enhance 3G performance (no LTE here.)
Wifi and Bluetooth are a little strip in the back next to the battery. 4G and 3G have separate antennas: http://www.anandtech.com/show/4465/samsung-droid-charge-review-droid-goes-lte/6
Check out this post where a guy connects an external antenna to the Charge:
https://plus.google.com/115676199813038165917/posts/jCmtnbQvgun
If anybody knows what each connector is for, I would love to know. My understanding is that 3G and 4G antennas each are separate and have their own receive diversity. It seems that the Charge uses a single antenna L1R2 to transmit, but I could be wrong.
Also, if G is ground, in where scenario would you use it when connector external antennas? I'm kindof a nube, and plan on doing more research.
screwed up 4G
Ok.. so I was reading some internet sites on how to boost signal.. should have come to this thread first. I have officially screwed up my Charge. I can get 3G but 4G is never connecting.. not sure how to test.
At one time I lost all signal strength, messing with R1 port.
Then i finally got that up.. I lost data messing with L2 port.. compeletly GONE!
Finally got that up.. don't know what L1 R2 is.. but yeah stay away from touching these ports. can't figure out how to get 4G.. One time I was on a hill and i saw 4G pop up! and then it quickly went away..
only have 3G speeds now..
Back to the Lab again.
Did you connect the ports with the device on? If so, it is possible that the it shorted the radios. This may or may not cause permanent damage.
I honestly don't know whether plugging into these ports with the phone on would cause a problem.
I believe that L1R2 is trasmit for the 4g and 3g radios. I believe that R1 and L2 are the receive for 3g and 4g, but I don't know which is which.
I could wrong about this, however. G is likely ground.
In any case, unless you know what your doing, you should be very careful. As soon as I figure out what each of the ports are, I will likely use them.
Look at the link I posted above where a guy hooks his Charge up to an external antenna.
It is very possible to hook up external antennas. There is no doubt about that. It has to been properly to avoid damage. It is possible that the whatever you connected to the port of the Charge has an internal short in it, which would cause damage the Charge radios.
Other considerations are impedance, SWR, tuning frequency, etc. The the right knowledge, it would be a simple matter to connect a very effective antenna for signal boosting on the Charge.

Not quite correct. I work for a company that specializes in antenna's for cell phones. The Charge, like most Android phones, doesn't have a workable port for an externally connected antenna - sure, you can hook up to the aforementioned port, but that permanently disconnects the phone's antenna (in our experience, from doing this lots of times). Impedance needs to be between 50 and 75ohms, SWR is not a factor, and the frequency is in the 1900 band (for most areas, for 3G).
You can use a wireless repeater (read amplifier), and that works really well - I go from a -98 to a -71, in my house.

Do you have any more information pertaining to what each port on the Charge is?
My Wilson repeater is nearly worthless (massive amounts of lockups, reverting to 1X, flashing red lights that aren't described in the manual, and many more issues even after experimenting with a multitude of installation types) and I just unplugged it after massive amounts of frustration.
In any case, I'd love to get specific information about the ports and how to properly use them, its kindof a shame to let them go to waste.

Yeah.. i believe i shorted the radio.. it never goes to 4G.. and it will sometimes i get the big X on the signal.. saying i lost all connection.. I really messed something up.. people gotta learn the hard way sometimes. well.. i'm working on getting a replacement. But i agree with everyone on the internet.. this is def.. a taboo thing to do.. don't mess with it.. like ESN hacking.. Sorry i can't be of help.. just wanted to post my experience.

Did you get the Wilson repeater for 4G.. it runs in the 700mhz band.
The HTC Thunderbolt has an external antenna on the battery cover.. take it off, and you get bad signal.. It's connected via 2 copper ends on the back of the phone. That would be interesting to copy/mimic on the Charge if it's available.
anyone else have this problem?
I have the latest HTC Driver.
When I first got my phone it was perfectly normal until I rooted my phone. I would have to try plugging and unplugging the Stock HTC USB multiple times for my computer to recognize my phone. It is getting pretty annoying. I was wondering if anyone else has this problem as well. (doesnt matter which ROM I use, problem continues.)

You sure it's not the cable ?
Or, perhaps the usb port connector on the phone, or the one you're trying to plug into could have loose/damaged contacts?
Obviously, somethings changed or different. Try to replicate as many of the conditions that you had when it did work, as you can.

i have three HTC phone charger. 2 of them are in perfect condition, brand new, and they both still give me the same problem. maybe, something is wrong with my phone inside?

I'm talking about the cable itself, and maybe that's what you are talking about when you say "htc phone charger."
As far as "something wrong with your phone inside," you perhaps are missing or not understanding what I'm referring to.
Look at your phone up close at the part where you plug it in. Real close. You should see 4 little metal strips... Contacts. I was trying to suggest for you to check if there was a physical issue, loose, bent connector on the cable or on that part of the phone.
Or, on the connector of the port on the computer you were trying to connect it to.
The fact that you have to do it several times for it to recognize, but that it at least DOES eventually recognize it, made me suspect it's something intermittent, like a bad/loose connector, or a cable that has one of the wires inside it broken.
I don't know what other than something having to do with the usb connector on the phone, possibly where it's soldered to the PCB, that would cause it to intermittently give you problems.
I bought one of these E888 android stick thingys however the wireless performance is almost non existent, it works, if I have my phone hotspot over it lol, but it won't connect to the router in the other room...

I've installed Finless custom Rom, moved the antenna and even clipped off the ground wire to prevent it shorting... however none of this seems to be working... does anyone have any other things I can try? Seems such a waste of what would otherwise be quite a good dongle
PS I've already gotten my money back on it so I'm open for experimentation

Definitely seems like something wrong with the antenna wiring. Shouldn't there be two wires?

google for "RK3188 wifi solder"
Alternatively you can get a wired USB->LAN 10/100 adapter for $6

Ha not sure, I don't think all versions have two wires im sure ive seen some shots where there is only one? :S
Maybe the lan thingy could work, didn't think of that, would make those powerline adapters useful for something finally lol...
As per the title I am getting a much diminished signal after changing the charging port to a new one.
The worst is when I grip it in my hand which would naturally be at the bottom - where the charging port is.
I only get LTE when I'm outdoors and indoors it's either H+ but usually H, E, or even NO SIGNAL.
I can't figure out what could be the problem. There are 2 antenna inside the unit that connect to the charging port but these are bluetooth and wifi. It doesn't appear to be an antenna for the network signal. Or is the frame part of the network antenna? I see some electronics in the frame when I dismantled and I don't know what that is for or how it connects to the mobo. I'm thinking if the frame works as an antenna maybe it's not connecting to the mobo properly.
Just to clarify I was having no signal problems before I dismantled the unit and in fact it was working exactly the same as my previous phone.
I actually don't know if the charging port part has anything to do with the signal antenna.
Any comments appreciated.
Hello,
I'm experiencing the same problems with my SM-G920F. After replacing the charging port the bottom mic isn't working anymore. I'm forced to call on speakerphone to get the sound to the other end of the line. The repair centre who fixed the phone said it could be because of a little off-point alignment when soldering the usb pin on the pcb. They also said that they experienced the same problems on different repairs for the S6.
Any thoughts?

Please start you own thread on your issue. It has nothing to do with this thread. Mod please remove this post.
I think I know what happened. When I took off the back cover plate it was glued to what looked like a Printed Circuit Board antenna and it was yanked by myself. Anyone know where I can get these type of things to buy and repair ?
