Where is the antenna part?

Hi, My phone is having very bad reception, and I tried the 3 radio roms.
Tmobile, HTC and rogers.
The Tmobile one seems to work better, But, when i go inside a build, I lose everything.
and standing near a window doesn't help either.
Can somone with an 8125 or 8525, tell me if the reception was better with those phones?
I used to have those 2 phones, and I always got reception inside a building.
I want to know if it's the Radio rom or a hardware issue.
Maybe, I need to replace the internal antenna?
any help would be great.
I use tmobile, and I live in manhattan
Thanks

it sounds like the phone itself since you tried different radios, I flashed just about every rom I could find and always had about the same reception. I wouldn't know where to find new parts though. I've seen dead dashs on ebay for parts.

thanks,
I got the phone used, and i want to know which part in the phone is the antenna,
it could be damaged.

It runs across the top of the phone, the top two screws on the back cover (the ones with the rubber plugs over them) actually hold it in place. It has a small prong on it that you can bend slightly if it isn't making good contact with the circuit board.

[Q] Death grip

Hi everyone
I have this problem:
http://www.youtube.com/watch?v=2Gu9oKlWq1Y
Anyone know how to solve this problem ?

Just as a disclaimer, every phone will lose signal if you grip it a certain way. Remember the iphone debacle?
But the quick fix is to just put a case on it. Your body will no longer interfere with the antenna and your phone will have the added bonus of surviving a fall.

Downside is cases tarnish the natural beauty of the phone that the cell phone manufacturers intended. I just take the risk. I would rather have a nice looking phone IMHO.

I already have this one http://www.otterbox.com/HTC-G2-/-HT...C4-G2XXX_color=20&start=1&cgid=desire-z-cases

gripping ANY phone tightly/awkwardly over the antenna will cause loss of signal. Some are worse than others, but it happens to any modern phone with an internal antenna. Cases help, but you're still going to be able to replicate it if you try hard enough. The phones are designed so that the antenna will more than likely not be blocked if you're holding it in any normal conventional way during regular use.
One usual culprit for the G2/DZ is the WiFi signal getting weaker when using the hardware keyboard, because your hands are covering the top and bottom of the device.

so isn't any idea to solve or help a little with this problem ?

Like I just said, there's nothing you can do other than just don't hold the phone in such a ridiculous way. You can't move the antenna inside the phone, it is where it is.
In normal use I highly doubt you'll ever see drastic signal drop because of the way you hold your phone. Nobody normally holds a phone in the way shown in the video.

So tell me how to play in gameloft games where all of them is in landscape mode

like I said, using the phone normally (yes even playing games in landscape) your signal shouldn't drop so low that you will be completely disconnected from the network. Don't get scared just because the bars drop.

But i already play at Order and Chaos and this game are also in landscape mode and unhappily i get lost connection every few minutes ;/ and the game has reconnecting.

There's nothing I can tell you. The antenna is where it is. If for some reason you're in a low signal area to start and you cover the antenna you're going to see loss of signal.

Tell me if i give back this mobile on warranty then they are able to solve issue ?

You're not listening. Every phone has this issue if you hold it in the right place. Its a cell phone with an antenna. Its just going to happen, there's nothing you or the manufacturer can do to "fix" it after the phone has been made.

I acutally thought this was a radio problem. I switched radios and noticed a slight improvement.

A radio update can help your signal a bit overall, but it will never remove the effect of strategically covering the physical antenna. What it would help with is a default low signal, that gets worsened to the point of disconnection from the network by covering the antenna (aka your normal signal could be higher, so that when it gets lessened it still stays connected).

[Q] Boost signal..?

I don't have internet at my apartment and I don't have plans of getting it anytime soon. I get a free Cricket Crosswave with my job so I haven't really planned on getting real internet service.. I have crap for data when it comes to Sprint. It's a shame that I have to use Wifi on my Sprint phone and hook it to my Cricket wifi just to have data.
Anyway, I know that if I call Sprint and complain they will send me their booster thing for free, but I have heard of people buying similar devices that don't require an internet connection to boost signal. Does anyone know of a solution?

answer
I think I can help you
I have tried to signal booster all it is really is a repeater you put a antenna up REALLY high or at least as high as the cable they give you let you and as long as you are in range of the base you should get better signal this works in theory. I am not so sure it works in real life good way to find out before you buy see if with in a mile or so of your house you can get the signal you are looking for if not then I am not really sure I would waste my time with it I mean you could as long as you can return it. These things are really truly made to just pick up a good outside signal and bring it inside places that well are shielded there not directional antennas or anything that would be able to be aimed (which would work better imo) how ever putting it up high in the air will tend to improve your ability to pick up signal in you are in a low area they are powered which means the SHOULD be able to boost low signal but again SHOULD is the key. Bottom line it didn't work for me and I have what is suppose to be good coverage in my area but.........I don't BTW here is what i tried take it or leave it up to you hope this helped I am not really good at this hope explaining things deal.

i'll probably have to give this a try some time soon.. thanks!

Can also try mounting on an old SAT dish, it can provide a huge gain of signal if you have one lying around, just point it in different directions till you get max bars. Show your signal in dBm if you can for more accuracy. The dish points in the direction of 45 degrees off the plane of the dish.

Remove the black tape that is on top of the actual antenna and you'll be left with a gold copper ribbon which is your real antenna. This help a lot because the black tape is blocking the radio wave that your antenna is trying to receive.

[Q] Signal drop (phone network, not wifi)

Hi,
I have had my HOX for 3 weeks now and since yesterday (so, not a new thing), I keep losing the signal in my appartment, in some places outside. Oddly enough, signal is OK (tho just 3-4 bars) in my office.
1. Could this be related to the WIFI antenna issue even tho it's not WIFI issue? In other words, is there a chance that by fixing the WIFI antenna issue, I can get solve this?
2. If not, what are my other options? The garanty is already voided so I cannot send it to HTC for repair (voided by an "unofficial repair center" after the screen got smashed by dropping it from like 1m... - it's very possible that the fall or their repair broke something else, but the repair was already 2 weeks ago)
Thanks for your help!

First thing I'd ask is are you rooted? Have you been playing with radios recently?
If not, the next thing I'd look at is trying to find someone else with a micro-sim, and asking to borrow it. If they still get a good signal on their network on your phone, it might be your sim card. I had a faulty one once which just started dropping network like you describe. It can happen.
If their sim card also shows poor reception, you might have an aerial issue caused by the unofficial repair centre opening the phone up. (Although from the feedback on the WiFi issue thread HTC have worrying repair standards too).
If you can't find another micro-sim, just try finding someone on the same network. This phone (when working) has excellent network reception (better than my previous Desire S) so if a side-by-side comparison shows a big difference in signal strength, again I'd think about getting the sim replaced.

If your replacement sim still has the same problem, then I'd consider opening the phone up as per the video guide in the WiFi Issue thread in the general section. Seems to be quite easy if you are careful. It is unlikely that the same aerial for the WiFi is also the 3G one, but I've looked at the tear down pictures, and can't read chinese! If i find out which one it is, I'll update this post. If not, just check all the connections.

Hi,
I have also been having this network drop issue but only near my office. The reason I think is that my office is between two towers and every now and then it tries to balance the traffic on the networks and hence keeps disconnecting devices from one to connect to the other one... However, I have cut out my normal sim into a micro sim and that was done by the guys at the shop from where I bought the device and they had said that if there are any issues, then please order a proper micro sim and use it....
I think that might also be the problem.....

All,
After checking that my SIM card wasn't in cause (used a friend's HTC One X to test my SIM card and test with his), I broke open the case and saw the problem.
The problem is the damn design of those antenna contact! I saw probably around 10 of those small metal piece that are supposed to be a bit "up" and somehow touch the contact area on the back cover.
I found that 2 of them (in two different pairs, they all seem to be in pair to create a closed circuit I suppose) were a little bit lower than their counterpart, so with a flat screwdriver, put them upright, closed the case and voila, I am enjoying network with full bars since yesterday.
If the issue comes back (and it probabl will, if they got bent the first time it probably means that the metal already was bent beyond its elastic deformation area), I'll probably end up buying a soldering iron a add some patch of silver to increase the height of the contact zones. That's .... just lame I am sure they had a good reason to do that, but seriously!?

Glad you got to the bottom of it. Yeah I think the design choice is forced from having the main body of the phone slide in at an angle into the outer case. If the two parts just clamped together like a more traditional phone build, then they perhaps could have used a different approach.
I'm putting off opening mine up (I have the dreaded WiFi drop issue) as my current case puts just enough pressure on the screen to act like a permanent squeeze, halting my problem.
Would be interested to know if the problem reoccurs like you said it might. Keep us posted.

Signal on top of a Mountain

Special use case. I am trying to get a signal when summitting 14ers (really high mountains). The current method is to send a guy up with a Verizon phone and a few other WiFi hotspots and cross our fingers that he catches signal for a few minutes.
I've scoured the web and can't seem to find any information on this. The Wilson Portable seems like it has the right idea, but is clearly designed for a car use situation. Should I be looking into using a Wilson Sleek with a larger external antenna and improvised battery backpack? Or perhaps there is a software trick to increase the power to the 2g radio? I'm really all ears.
I would love to figure out a way to simply slide my Nexus 5 in a case of sorts with a ~3ft collapsible antenna on the top. Would this work? Does it need to be in physical contact with the actual antenna, or could it just be in contact with the backplate?
I really hope someone has an idea on this subject. I find it so hard to search for!
Thanks again,
Matt

Ingress? lol
Yeah.. I wouldn't have much of an answer since with any booster, there needs to be a signal to boost.
I've thought of using your idea with a booster and a portable battery, but have field tested it yet.

I've got a Nexus 5, not sure if we have an external antenna jack or not. A lot of phones hide it under the battery.
You'd want a Yagi-style antenna. There are lots of instructions for making them with stuff like fishing pole tubes and tig welding tubes to make them ultra-light and foldable/dis-assembable for hiking purposes.
http://www.ubersignal.com/blog/yagi-antennas/
Yagi's boost transmit and receive both. They're highly directional, so you have to point them at the right spot.

Get a sat phone. Or climb 14'ers that have cell towers on them.
I climb a lot in the Sierra Nevada and almost always have service anywhere over 13000 ft. They're a narrow range close to population though. If you doing that in the Rockies I wouldn't trust cell service.
