Hi, I want to buy an external antenna to boost my 3g signal in my room.
I saw several antenna but where do I connect it ? in the headphone port or in the back of the phone near the sd card ?
Thanks !
Don't do it! There's a external antenna plug near the sim card if you plug in an externall antenna you will not get anymore signal some people have tried it and that's what happenned

Well, you can find connector at the back of your cellphone near sim slot, a small pin. And my frind is using external antena without any problems, so give it a try

So, i was wondering, coukd it be possible to plug an external wifi antenna to gain great wifi support?
@ HTC Wildfire w/ XDA App.
Anyone?
@ HTC Wildfire w/ XDA App.
The phone would have to have an external wifi antenna port, and I have never seen a phone with one.
or you could open the phone, track where the wifi module is and sold a cable to make an external plug for the antenna.
why not just use connectors from HTC's female to a regular usb female and connect the WiFi adapter to it?
the hardest part is not connecting the two,
It's making so that HTC recognizes it as a wireless adapter and be able to use it.
But another problem would probably be that the Wireless adapter would take up too much power from the phone, which will: a. drain the battery very fast or b. not get enough power and therefor not work at all.
This is just my guess, I really want this to be possible in the near future..
Is there a small slide out antenna on the market that i could connect on the connector @ the back of the samsung galaxy s near the sim.
I want to boost up my signal strenght becouse me 3g doesnt work that good in the area.
Any idea's its no problem to customize my backcover
From my point of view its a GSM testing cable connector for the hardware support.
Unfortunately nothing to extend range or to improve signal and not used like some older mobile phones for an external antenna when pluged to a car mount.

You are certainly wrong. I had some problem with my antenna before and by inserting a thin copper wire in that plug, i could got signal. It is definitely an external antenna plug. You can see the connection between that plug and internal antenna plug on the mainboard.

So just stick a piece of copper wire in it?
Do not try it!
It's DEFINITELY an external antenna conector. I've used it to get signal in the middle of nowhere.
That said, DON'T DO IT!
It's VERY easy to break the conection to the internal antenna. Your phone will have no signal afterwards, only with an external antenna. Some had no signal at all, even with an external.
It happened to me, as detailed in this thread.

Hi Guys,
This is a reference thread for anybody who has patchy reception and is considering using an external antenna to boost reception.
I have found that the patch cable required is the same as most other samsung phones.
The particular cable I used is this one: http://www.cellink.com.au/productde...=1&pcr=WES0830&tsb=Samsung&tsm=Omnia+2+(i8000)
I imagine that the same type of product would exist overseas as well - but if you are in a tight squeeze Cellink distribute worldwide.
Note that plugging in this cable disables the internal antenna (so if you don't have an antenna plugged to the other side of the patch cable then you will lose reception immediately).
Finally note that YOU WILL HAVE TO REMOVE THE BATTERY COVER TO USE THE PATCH CABLE. I'm hoping to get a second cover and drill a hole in it so that I can simply plug the cable in through the whole. I can confirm that there is enough clearance to drill a hole and plug the cable in that way.
Let me know if you have any questions.
I quite like the idea, but I have a few concerns:
Does the antenna work for both internet (all networks), wifi, gps, and normal cell connectivity?
Would one theoretically be able to connect an RP-SMA antenna, I have some nice wifi antennas lying around
I have read some concerns about the manual switch responsible for turning the internal antenna on / off is not that reliable and can cause issues stopping your internal antennas from working

Would one theoretically be able to connect an RP-SMA antenna, I have some nice wifi antennas lying around I'm not an expert here but from my limited knowledge: (1) you would need some kind of patch cable because the standard patch cable outputs to a male SMA connector (and not an RP-SMA) and, (2) there appear to be different antennas for different purposes (wifi, mobile network, etc.) my understanding is that a wifi antenna is not optimal for boosting mobile signal - that said it may or may not provide a boost over the internal antenna.
I have read some concerns about the manual switch responsible for turning the internal antenna on / off is not that reliable and can cause issues stopping your internal antennas from working I think this is an issue with older samsung phones. I have experienced no such issue with my external antenna (over around 10 uses). I'm not sure but I don't think it actually uses a manual switch - the reason why I say this is because when you unplug the antenna it takes a few seconds to switch back to the internal antenna.

I was thinking about using something like that. My problem is that 3G signal is very weak in two places where I spend most of the time - home and work. And for some reason phone is preffering 3G even if signal is so weak that internet is not working. So I had to turn off 3G. But it seems stupid to have HSDPA capable phone using EDGE only.

I can confirm that this setup will be awesome for that.
I haven't drilled the hole yet (in the case that is) - but once I do that it will make the setup much more functional.
On the back of the Epic 4g there are 4 external antenna ports labeled R2/G W1 W2 and R1.
Is it possible to hook up and external 4g (WiMax) antenna to one of these ports?
If so, what port would I connect to, and what type of adapter and antenna will work?
Thanks
A quick search of the forums for "antenna" will answer your question.
However, basically those ports are meant for FCC testing and from the other threads anyone who has tried to use them has caused the internal antenna on the phone to become perm. disabled or other corruptions.
I've seen the tear down and I'm hoping someone has already tried connecting an external antenna to this phone and can share their result. I'm hoping to be able to attatch one mounted on my car and wire up a removable pigtail for use while driving through weak signal areas.
The connector visible under the battery should be the main antenna connector
