[Verizon Droid Charge] Goldenlance:
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.
[Verizon Droid Charge] xdadevnube:
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?
[Verizon Droid Charge] kvswim:
The G is ground.

[Verizon Droid Charge] Wasteland_Vixen:
so?

Anyone find a definite answer on this?
[Verizon Droid Charge] xdadevnube:
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.
[Verizon Droid Charge] bomix:
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.
[Verizon Droid Charge] xdadevnube:
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.
[Verizon Droid Charge] chevybythesea:
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.
[Verizon Droid Charge] xdadevnube:
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.
[Verizon Droid Charge] bomix:
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.
[Verizon Droid Charge] chevybythesea:
PM me - we'll get it figured out for you, no problem.
[Verizon Droid Charge] bomix:
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.
[Nexus S General] kevlars9:
So I just got back from best buy and I noticed that their nexus s 4g display model had a more silverish, dark grey battery cover. Has anyone else seen this? I know mine is black but I thought it looked pretty cool.
[Nexus S General] obsanity:
Interesting. But why would Google change the design and not have this all over the news.
[Nexus S General] kevlars9:
I have no idea. Ill take a picture next time. Maybe tomorrow? But it def. was different.

More silverish and seemed to have a little more texture.

[Nexus S General] fraspas:
Was it a real working model or one of those fake shells?
[Nexus S General] kevlars9:
It was not a live unit.
[Nexus S General] LoveisPeace2012:
J noticed that too its how the dummy units look
[Nexus S General] kevlars9:
Not all of them do. Reason I asked was just to see if anyone has one. Looked pretty sweet and was wandering if that was the only change.
[Nexus S General] ZeroCool84:
Maybe the change in color/texture was from people touching it a lot and people's oils and dirt rubbed off the top layer?
[Nexus S General] kevlars9:
Def. not. Ill try to take a picture tomorrow. It is a completely different back cover.

Pretty much the reason I am bringing this up is, because I'm curious to know if maybe this is a newer device/ model. Maybe fixing signal issues? Who knows. It could just be nothing but def. Interesting

Great ROM compkid!

Few issues:

the JobManager.apk you added in page...somewhere in this thread isn't working for me - just says Task Manager was not installed without any indication of why >.<

Swype doesn't work, but of course you're working on that.

Battery life is pretty bad - this may be tied into the task manager issue, since when I check the battery use page, even with GPS off, GPS Status (uninstalled today since it was draining too much) is using a ton of battery, and Android System seems to be inordinately high...FYI: running 1.1 w/ EF10
[Epic 4G Android Development] only1penny:
i'm running 1.0 and battery life is fine. i'm at 17hrs 9m 35s right now with moderate use. i leave gps on all the time & usually wifi all the time.

Another suggestion why doesnt anyone here use Zeam instead of TWlauncher? I have been using it for a while and it seems simpler and Faster. Bonsai started to use it.

Very few, that's why it's the best modem for me. The posters above me said EC05 and EE03.

This ROM is fantastic! Even better than the first time I tried it. I do still have the problem of it seemingly cycling charge (if that makes any sense) while it's plugged in. The phone seems to act as though it's being plugged and unplugged; I've tried different chargers/cords/outlets. I searched this thread but came up with nothing.

Is this a known issue? Is there a fix? If not, this is still by far the best gingerbread ROM I've tried.
