[Q] Hardware issue - Antenna - Poor reception - Galaxy S II Q&A, Help & Troubleshooting

Hello guys,
I'm having a reception issue with my beloved S2. In my opinion it is a hardware issue, because when I connect some wire to the external antenna jack at the back of the phone (that connector at the left of the sim card, just above the battery), the receptions improves.
Does anybody know where S2 antenna is at? Can it be replaced?
Note: I'm using the original USB-flex. I know it messes up with the reception when it is replaced.
Thank you in advance

External antenna for TD2

There are some places (like my parent's house in a farm) where phone signal is quite good outside, but terrible or no signal in the basement. My HTC Tytn II has an external antenna connector on back, but TD2 doesn't have it.
Do you guys know if there is a way to plug an external antenna in a TD2? For my conditions, it seems the best solution would be something like the zBoost signal "extenders", but they are quite expensive. Have you guys used something like that?
Thanks.
That connector you're talking about it's for GPS and not for regular antenna.
I guess there's no away you're going to plug any antenna extender in the Topaz.

Anyone know of an External GSM/GPRS Antenna port on TP2?

Does anyone know if the T-mobile version of the Touch Pro 2 has an external antenna port?
I travel through Texas and Use T-mobile (The coverage is imperfect but can be improved with an external aerial antenna)
In the past I used the Tmob Wing which had a rubber pop off cover on the back that allowed access to the antenna port.
I really miss using my external antenna. I've searched Google and XDA with no luck. Called Tmob PDA support no help there.
Any help on locating this elusive port would be appreciated.
Thanks,
m

err that threads about gps antenna ports, hes on about gsm
For more clarification not GPS but GPRS/GSM
I have this antenna from Wilson Electronics.
http://www.wilsonelectronics.com////ViewProductB.php?ID=21
This for 806-866 MHz / 896-939 MHz / 1850-1990 MHz.
These antennas drastically improve all cell use and improve battery life in the process because the phone does not have to work as hard to acquire or boost a weak signal.
I also believe this makes mobile phone use safer with regard to radiation.
Anyone remember the old days of Cellular? Everyone had a cell antenna on their car. This antenna is similar to those.
I hope someone can help me find out if the TP2 has an antenna port like my T-mobile Wing had.
Thanks,
M
Fil - minoch may be looking at GSM/GPRS external antenna connectors on the TP2, but the themes are connected. There are no - zero - external antenna connectors on the TP2, whether you're looking for GPS, or cellular antenna connectors. It's the single failing on the TP2 that I can identify, regrettably.
Depending on your country, re-radiator antennas for GPS and/or cellular signals are available to mount in your car, but you must look carefully to see if such devices are legal to use in your country.
minoch - I would add that the antenna linked above by you is all well and good, but without an antenna connector (socket) needed on the back of the phone, it's about as useful as a roof rack on a helicopter.
Thus, a re-radiating device of some kind is required.
This article should help you understand the tech behind the solution to the problem: http://www.tech-faq.com/cell-phone-signal-booster.shtml
Thanks for the information Roger.
I suspected this was the case but hoped I was wrong. I guess I'll have to find some sort of induction connection (Those antenna decals that have a wire to hook to an external antenna) It won't be anywhere near as good as a direct connection but hopefully it can help a little.
A shame such a nice expensive phone as the Touch Pro 2 would not have any antenna ports. I guess HTC had to cut cost too..........Damn this Economy.
Thanks,
Minoch
Must admit, it surprised the smelly stuff outta me when I realised there wasn't an antenna connector on the phone. really silly ommission, given all the hooplah regarding hands-free usage while driving your car, and all that similar malarky.
Oh well, guess they throught that the internal antenna was good enough, or, as you suggest, they had to trim down the expense by dropping an external antenna connector and associated printed curcuitry, housings and case adjustments for a grand total of maybe 3.50 GBP per unit before packaging (with adjustments for economies of scale, etc)?

[Q] Antenna Location/External Antenna Port?

Hello everyone,
Thanks to the recent events around the world of communications being hampered, I've gotten interested in direct mobile to mobile communications, without the need for cell towers.
My question is: 1) Is there an external antenna port anywhere on the EVO 3D? I didn't see it. 2) Where is the internal antenna?
Thanks for your insight.
EDIT: Seems I've found the internal antenna's location. Per this thread.
so the antenna is on the bottom right?
Just bought the EVO 3d GSM. Building a booster for it. Using a Wilson 3 watt booster and Wilson Cradle as there is no antenna connector.
I would assume that you would place this phone in the cradle Upsidedown to get the maximum signal being the antenna is on the bottom of the phone.
Am I correct? Please Advise.
Thanks.

[Q] Weak or no signal on GTI9100

Recently my provider signal got so weak that now if I am indoors the signal is gone until i go outside. Tried to upgrade via Kies to ICS but the problem persists.
When I stick a small piece of wire in the external antenna connection, my signal goes to full and is perfect!? Is this a hardware or a software problem?
It seems that the internal antenna is not responding because as soon as I remove the wire the signal is gone or is minimal.
For now I keep the wire connected behind the cover and the phone is usable.
As I can see this is a common problem and many complaints are posted on this topic all over the place.
Can anybody help? Thanks in advance.

Internal antenna
Thanks for the link,
Unfortunately I made a mistake by trying to connect an external antenna, not being aware of the consequences. Reading the posts it looks like I will have to bridge the external antenna socket and connect it directly.
Time to bring out the soldering gun and get to work.
I will try a few other options in the meanwhile.
Sh.. happens, anyway thanks for the help, regards...
