Hi all
anybody knows a shop link for GPS Coaxial cable for MDA Compact IV ??
my gps cable is fauly after LCD Screen replacement ! it recieves no GPS Signal.
Thanks in Advance
Hi
I bought gps / wifi coaxial cable on ebayz! about 7-8 euro!
sorry for my bad english!
Bye
Can you send me the link,where have you ordered? thanks
Hi,
Coaxial cable is utilised to provide a connection between the GPS antenna and receiver. The cable distance can be critical. The antenna must amplify the GPS signal sufficiently to overcome any cable losses associated with the cable run utilised. For finding a shop link for GPS Coaxial cable it is beter for you to search over internet. Also you should try to contact the shop dealer from where you had bought the cable.
Thanks

Hi. Im also looking for new coaxial cables. Anyone know where to find em? I couldnt find any on ebay or by googling.
Edit: Found it from ebay co. uk "OEM AERIAL ANTENNA WIRE RECEPTION FOR HTC TOUCH DIAMOND".
Can anyone measure lenght of GPS and WIFI antenna cables? I mean anyone who have their phones opened or plan open it.
Asking it because i cant find coaxial cables to HTC HD2. But i belive that HD2 and Touch Diamond use same lenght cables. Differnce can be only on GPS cable color if lenghts are same. On HD2 they are white.

Bluetooth/Wifi cable is 9,5cm and GPS is 6cm. I changed my coaxial cables sometime ago and now everything is working fine.
Very big thanks. You helped lot and not only me. I think you helped many HTC HD2 users who need replace these or one cable.

you can find GPS in http://shop.ebay.com/i.html?_kw=GPS&_kw=Coaxial&_kw=cable
Man, last ones on your searc link are GPS cables. Another ones are wrong.

I can confirm that wifi/bluetooth cables are same on Touch Diamond and HD2. I runned over web and tryed find one for HD2. Nowhere. Maked deal to Touch Diamond wifi/bluetooth cable (big thanks to Teemu7 about lenght). Now cable replaced and all work perfect.
I have GPS Coaxial cable and it really works very well.
hmm i might have to give it a try
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.

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.
is it possible to use this phone to bridge my neighbors wifi signal in to my house?i have his permission to use it.in fact i put the router in his house and give him ten bucks a month.i can only pick up his wifi in my daughters room and garage.any apps or anything?
If you mean you want to have WiFi data in AND WiFi tethering out, no its not possible. As far as I understand it, WiFi tethering essentially turns your WiFi receiver into a transmitter, and both can not be active at the same time.
You could just get a range extender and put it in your garage or your daughters room, that would boost the signal in your house
Personally I've never liked those range extenders. While there is no way that I'm aware of to do it with the g2x, it can easily be done with a few pieces of network equipment. Get yourself a wireless ethernet bridge, and put it in your daughter's room. Connect it to the wireless network, and plug a wireless access point into the bridge.
Not a cheap or elegant solution, but it should definitely work.

yeah i was just looking to do a free-be way if it was possible.i know about the range extenders but never thought about your idea..why dont you like wireless bridges/range extenders?
I don't like them either but its a simple solution, I've tried them before and they seem to lose connection randomly.
Now I'm not 100% sure of this, but I think you could do this with a wireless router running custom firmware (DD-WRT).
Wireless router picks up the signal and bounces it back out. Maybe it's worth looking into

maybe if you have a usb wifi adapter set up a ad hoc connection then go back to network and sharing click on adapter settings then sharing and shared it with the usb wifi adapter thats one way to doing it

yeah im going to look in to this.im not sure if i have the right router but i have a couple of old ones laying around here.also gonna check in to that usb adapter idea one of the other guys suggested.thanks all.
So my house doesn't have very good 4G signal.... I have to FORCE 4G and either be outside or top of a window. That being said, I want to find a spot with 4G and leave my phone there.
Is it possible to connect to a router to extend the wifi signal? Or should I get a long usb cable for tether? Any tips on getting a better signal? Thanks!
Sent from my SCH-I535 using xda app-developers app
It is "possible" is it real feasible?? not really.... It would still require a long usb cable a computer and a router... You would need to USB tether the internet to a computer than bridge that connection the the ethernet port on the computer then run that ethernet to the input of a router... Like I said not real practical.. Look into a Signal repeater... They are a little pricey but work really well in most cases...
Something like this, http://compnetworking.about.com/od/wireless/ss/wirelessgear_7.htm , would be your only wireless option. Like dr12volt said tho, it's around 100 bucks for something like that.
Also(taken from above website):
However, due to the nature of this technology, most wireless range extenders work only with a limited set of other equipment. Check the manufacturer's specifications carefully for compatibility information.

Hello,
Can you please tell me what is te purpose of the white coax cable conecting the charging module with main board.
I understand that is a antenna cable, i've broke the c connector by mistake and the phone is functioning ok, 3g, 4g wifi .
Thank you
possibly a second antenna is available
I don't think smartphones today have only one antenna, to use MIMO on different streams smartphones have multiple antennae
so you might have broken one, see and compare connection speeds
if you have 802.11AC router the maximum supported speed is 866Mbps
if rooted, you can use LTE discovery and see if you are able to use carrier aggregation
