Is there anyway that I can improve the reception that I get at home. I am not talking about those signal booster stickers, but something like a signal repeater.
Does anyone know if such a device exists
Ashby
never heard of it
you could try googling for
gsm transciever or gsm repeater or something
I don't know how it work, but my O2 XDA II mini have something behind like antena connector. It should be better if using this external antena instead of internal antena.
Best regards,
Arto
Do a search on google... they do have repeaters for buildings, but they can be expensive. You essentially, mount an antenna on the roof our your building, and a repeater amplifies to another antenna somewhere in your house. I was looking into amplifying the GSM signal into my basement...
Signal Booster???
I haven't tried this, but is this for what you were looking?

This is what I was looking into:
http://www.cellantenna.com/repeater/building_repeater.htm
:?: I need a cable to connect to the phone antenna ports on the device - the port is smaller than the ones to be found on some mobiles (such as my old trusty Nokia 6310i) and I need to find out what type of connector is needed.
Does anyone know where a cable can be obtained or what type of connector is needed ?
I need a connector also
It took me weeks to find the special connector for my XDAII. Now I'm in the same boat for the Universal (JASJAR). I've been searching the net for a while to no avail, but hopefully I find one soon and let us know. :?
Sorry just too lazy to go through the manual so decided to ask the enlightened friends on this forum. I want to know if the antenna socket provided at the back of the Universal is for GSM signals. The GSM signal in my home room is too weak so I thought that attaching an external antenna would be beneficial to the strength of the GSM signal. But obviously even if it is so attaching an antenna would be possible only once we have found a suitable connector.
Kind Regards
I mounted an antenna outside my house
For the last 2 years (with my XDAII) I've used an antenna I ran through my outside brickwall and mounted outside my house. It helped the phone go from NO reception to a pretty good signal. I still have the cable running to my office/desk and all I need now is the connector. It has to be out there somewhere. I ended up buying my previous connector from http://digikey.com, but it ended up costing $30 ... but it was worth it. I'll do more digging today and see if I can find out more.
Oh and by the way, I was using GSM on my XDAII and the manual for the Universal says the connector (closest to the center or USB) is for GSM/GPRS.
Anyone find out what adapter fits the jasjar? My adapter for the pda2k does not fit.
I'm still looking
I've sent emails to PDAGold, HTC in Taiwan and i-Mate to not avail. I'm going to keep on looking. Obviously someone has to know.
Some progress - I've found out the connector type
The connector on the phone is a Amphenol MHC-H196.
I've posted a pdf with all the specifications of the connector on the circuit board ... http://wiki.xda-developers.com/uploads/MHCH196.pdf
Now it's just a matter of finding the correct adapter.
Well I gave up trying to find one and made my own
After spending many hours looking and getting an official "not available" from digikey.com (who I got my XDAII adapter from) and imate techsupport ... I decided to make my own. I haven't been able to test it with my Jasjar yet, though, since it's still being repaired at Topp Solutions in Miami.
I ended up using 26 gage solid wire (which is .4mm diameter) and a .062 inch (1.6mm) diameter female pin connector. This is smaller than the diameter of the connector on the phone, which is actually 1.82mm. Although, I expect it to expand slightly (permanently) when it's slid over the connector on the phone. Obviously, it's very crude for now. I just want to see if it works then I might make a prettier one. I included some pictures for fun. By the way this cost me about $9 in material (which I can use for other projects) vs. $35 for the last adapter I bought for my XDAII through Digikey.

Did you see the interesting comments made by WilsonsElectronics. HTC really stuffed up with this one.
Is there any news on this matter.
At the moment I have sent an information pack to www.pasternack.com and I am currently waiting for a response. These people do customised products. See under technical support. I will keep you friends informed.

I am after an adapter to get a signal booster... www.digitalantenna.com
I talked to them about three products. there email follows
Description Part Number List Price
60dB gain repeater system 4KSBR-50U $699.95
40dB gain repeater system 4KMR-30U $559.95
Direct Connect Amplifier DA4000 $299.95
DA4000:
The DA4000 amplifier must be purchased with an antenna and cell adapter cable and is a direct-connect system. The antenna is placed on the roof and connects to the inside amplifier which with the correct adapter would then connect to the cellular device. We have many adapters for different phones and air cards. If we do not have the adapter for your type of phone or air card the other option is a wireless repeater. However the direct-connect amplifier can provide higher performance because you are directly connected to it. Please use the link at the bottom of this email to download our 2006 on-line catalog. On page 28/29 is our Cell Adapter Cables which lists the adapters per make/model of cellular phone or PC card.
Description Part Number List Price
Direct Connect Amp. DA4000 $299.95
9dB cell antenna 288-PW $129.95
Cable 340-50NM $79.95
Adapter Cable pg 28/29 $19.95
4KSBR-50U:
The 4KSBR-50U system comes with an external antenna, 50' cable, amplifier/repeater, power supply and an internal antenna. So the external antenna can be installed on the roof with the cable going to the amplifier/repeater inside the house. The internal antenna is also plugged into the amplifier/repeater and is installed inside the house. There must be 40' separation and a wall/roof/bulkhead structure between inside and outside antennas.
With a good cellular signal outside the house the 4KSBR-50U system can reach as far as 40 feet from the internal antenna. Generally the SBR can penetrate 1 or 2 inside walls only and each wall will reduce the 40 feet coverage. Also keep in mind the weaker the outside signal the closer you will need to be to the inside antenna. The 4KSBR-50U system must have a signal that is at or greater than -90db to be able to amplify/repeat it.
4KMR-30U:
The 4KMR-30U, 40dB gain dual band cellular repeater system, comes with an external antenna, 30' cable, amplifier/repeater, power supply and an internal antenna. So the external antenna can be installed on the roof with the cable going to the amplifier/repeater inside the house. The internal antenna is also plugged into the amplifier/repeater and is installed inside the house. There must be 20' separation and a wall/roof/bulkhead structure between inside and outside antennas.
With a good cellular signal outside the house the 4KMR-30U system can reach as far as approximately 18 feet from the internal antenna but will not penetrate walls. Also keep in mind the weaker the outside signal the closer you will need to be to the inside antenna. The 4KMR-30U system must have a signal that is at or greater than -90db to be able to amplify/repeat it.

I haven't checked this very far yet but the picture seems to match...

Its the Nokia 359914 Multi Manufacture Cell Phone adpater, You stick a velco thing on your phone next to the internal adapter, and slide the nokia adapter into it. This is NOT a direct plug in into the External GSM jack of the HTC Universal device ( ie Jas Jar ). But looks like our only safe option. Not sure how the velcro thing goes on the device, the Jas Jar has a plastic back ( over the battery )???
Works on these networks, the site says : 900MHz/1800MHz/1900MHz/2100MHz networks
..."This is an extremely effective new kind of adapter, it works on a similar rinciple to the clip-on adapter, with the exception that it is tuned to work on more frequencies. We have tested it on all UK frequencies including 3G, and we know it works on the American 1900MHz band as well! This adapter was originally designed to work on Nokias but we have successfully used it on other makes of phones, making this a (hopefully!) truly universal adapter. It will work on 'candy-bar' style phones which have an internal antenna.
This adapter is two-piece, one piece is a velcro pad which has sticky-back plastic on it, and sticks onto the back of the phone over the internal antenna. The second piece is the adapter itself, which has velcro over the inductive plate, so it can be easily removed, and has a lead so it can be connected to an external antenna. '...
Where did you get the Information that it's a velcro adaptor?
reading the Page it says:
Plug-In Adaptor for O2 XDA Exec
More details about plug-in adaptor in general:
This kind adapter is called a plug-in adapter, for the simple reason that what it does is plug straight into the port on the back of the phone, and provides a cable connection to the antenna.
The plug-in adapter is preferred to the clip-on adpter, as it works on any mobile network.

I wrote them an email i'll keep you informed.
If you can get a plug in one then fine, but further down the page is where I get my info from. I highlighted in bold, just in case you cant see good.(Ha).
I'll bet the Jas Jar gets allocated the valcro one. As my experience is that its very difficult to find a plug one for the Jas Jar /O2 Exec.
Although I learly can read your bold text and being able to find this on on the page i really have no clue where you find the connection between the velco apdator and the O2 XDA Exec since it's marked with plug-in adaptor. Well we will see.
My apologies, yes "Plug-in Adapters", for "XDA, XDA II, XDA IIs, XDA Exec "..
BUT be carefull, the GSM external jack is very weak as per Wilson Electronic comments. Post me any confirmations of the plug in adapter working.
'Universal' adapters that apparently plug in
Their News page has a paragraph that describes a new adapter for various flavours of the Universal (although calling it Wizard to add to the confusion!) and warns against plugging in incompatible adapters. The adapters page lists the HTC devices under 'Plug-In' not 'Clip-on'. So that's why I posted.
I sent an Email after posting here, but it sounds like they are a small outfit so be patient!
Be careful with making adapters for transmitting antennae. For receiving antennae you can get away with almost anything, but for a transmitter a bad match on a connector will create reflections and emissions; it might even damage the transmitter (don't know if that's a problem here). If you don't see a clear increase on the reception bars with a well placed antenna, the adapter may be sending all the power straight back, doubling the voltage at the transmitter. Make sure everything is matched to 50R.

Reply from 'Boatersphone'
Can you do an adaptor from the obscure Amphenol MHCH196 socket on the HTC Universal Windows PDA phone? (XDA Exec, MDA Pro etc.). Presumably the other end is an FME f connector for the 'standard' phone antennas. Or alternatively the other end is a portable (non-mounted) antenna on 1800/2100MHz.
Many thanks

Hello,
Yes we have an adapter to connect the HTC Universal to one of our antennae and you are correct about the FME F connection. We don't supply an adapter direct to an antennae, only in a two-part system via an FME connection, to allow for changing of either part.
If you require a portable antenna we have a 3G/Multiband antenna with a magnetic base (on 850/900/1800/1900/2100MHz frequencies) or we have a T-bar window antenna, which is 3G/Triband, although this doesn't produce as good results as the magnetic antenna.

Hey guys, just got my DInc2 Monday and found that the signal strength was no better than the Eris I had before it. The problem with the eris was that there was nowhere to connect an external antenna. After messing around with my new DInc2, and reading this forum, I found that by using the antenna that I bought for my eris: http://www.amazon.com/Wilson-Electronics-Trucker-Mirror-Antenna/dp/B001DTZ25A/ref=sr_1_1?ie=UTF8&qid=1323615483&sr=8-1
and the passive antenna adapter
http://3gstore.com/product/1691_passive_antenna_adapter.html
that I never could get to work to boost my eris' signal, I was able to DRAMATICALLY increase my signal and data speeds!!!
I have the antenna pointed in the general area of my closest tower.
I cut the end off the adapter, and stripped the wire. I then slid the wire into the antenna contact on the PHONE SIDE...not the cover. I went from 2 bars of signal and an average of -95dbi without the antenna, to a STEADY 3 bars and an average of -86dbi with the antenna. The back cover has to be off for this to work, so it's only a fix if you are at home, or somewhere stable where you can just connect it and set the phone on a table somewhere.
If anybody knows where I can pick up some kind of small alligator clip or ANYTHING that would allow me to more permanently attach the antenna while I'm at home, I'd love to hear it. I think if I had a better connection between the phone and the antenna, the signal would be that much better.
Here are the speedtests I took this morning. The first three are without the antenna, and the 2nd three are with the antenna
Antenna fix
You could get a spare back and drill into the area where the connections are and solder the wire to the contacts on the back.
Try it with the stock antenna intact. If the signal is not better, interupt the trace of copper for the stock antenna.
Enjoy...
Poking around in the back of my phone, I pulled off a tiny rubber cover located just above the SD card slot. Just underneath is what appears to be an antenna port. I have a Wilson antenna that I used with an old flip phone from back in the day, but the adapter I had did not fit. I ordered this one off of E-bay: Wilson 359909 Antenna Adapter LG, Motorola, Samsung,HTC (160641678739) - even though it did not explicitly state it would work on the Dinc2. In the meantime I spliced off the end of the adapter I already had and put the exposed wire in the antenna port. I noted an immediate increase of signal strength of -5dbm. Unfortunately, the ebay adapter arrived and it also does not fit. I think if we could find the right size adapter, we could drilll a hole in the back of the cover and it should seat nicely. Anyone have any thoughts?
I see that port. I didn't get any signal at all when I put my wire into it though. Anybody know what this port is for if not for an antenna? I find it hard to believe that nobody has noticed this before.
I find it hard to believe that nobody has noticed this before.
I agree. Maybe wishful thinking got the best of me!
I just hope there's something to this!
I shoulda thought more before posting. There is no doubt in my mind that I got a signal increase with the external antenna as compared to the last signal reading prior to taking off the cover (and having no signal at all).
Question is - could I have inadvertently touched something else in addition to that port?
At work till tomorrow afternoon and will retest then.
It IS an antenna port
I have attached pictures of the "setup", and a screen shot displaying my dbm's with the cover off and the antenna attached. Cover on signal status was -96 dBm and with the antenna attached it was -87 dBm.
Hopefully this will get someone a lot smarter than me interested in figuring out what kind of adapter would work on this port.
Thanks in advance for any and all feedback!

Umm i get 2meg download speed with no app and the back on. Remember the phones internal antennal is actually the back door of the phone. Did you do those first speed tests with the back on? Try flashing a new radio. The newest one ending in .1111 is great!
Sent from my Incredible 2 using XDA App
Thanks for the advice! I flashed the .1111 radio a couple days ago and have noticed that the dead spots on my 1.5 hour drive to work have gotten shorter and my average dl speeds have increased from an average of .5 Mbps to about 1.2 Mbps
My hope is that with the right adapter, I could plug in an external antenna (pictured in my previous post) and cause those dead spots to disappear all together.
By taking the back cover off and plugging the bare wire of the adapter into the port directly above the SIM card slot, I get better reception than I had with the back cover on. Problem is, it's a very precarious connection. I think if I could find an adapter that actually fit in that port, I could drill a hole in the back of the cover and plug and unplug as needed.
I have a very strong network signal outside my house or near my window. But inside my house the signal strength is very poor. Is there any external antenna to recieve strong signals.?? ( other than cell phone repeaters)

Don't know much about it but I think you need external devices to detect the slow range
some Siemens phones had on the back an antenna jack, with those yes you could enhance the signal with only an external antenna
Increase Signal?
5 Quick Ways to Boost Your Cell Phone:
1. A simple piece of wire
Very simple and cheap method using insulated wire.
2. Major boost using empty cans
This one got me from zero bars to three bars, in an area I never get a signal in. I keep this one in the trunk when the weather sucks. The additional wires I got on eBay for a few bucks each. Takes less than five minutes, looks stupid but works well.
3. The paper clip booster
This one didn't work as well as I had hoped, but it did give me an extra bar (which is great when you have zero bars). Good if you're in the office and need to use your cell, maybe for making one of those "personal" calls.
4. The Tesla coil effect
Hands down the easiest one I found. All you need is tape and those little twisty-ties you get with cheap garbage/sandwich bags. Worked better than the paper clip for me.
5. An old radio antenna
this year the mobile signal is weeker than ever. When I wanna upload an picture or share sth with friends. it is not available. uhhh
Did you try to root your phone and check any cutom ROM? In my case custom ROM gave me much better signal on my SGS3
Good luck!

Thank you,
Thank you
is it possible that the surrounding houses are aluminum sided."
if so the signal is getting bounced rather than absorbed. this creates whats called "signal bounce confusion"
I have try this trick with the cable.the phone choose the best signal between internal and external antenna.and of course it will get better signal from external antenna. it works but you must use a soft wire...the second time I did it I try to use a wire from ethernet cable...I broke the clips inside and the internal antenna is broken..now I use the external antenna with a soft wire from usb cable. So becarefully when try thinks like that.
It's great for your method, thank you.
I have a Sprint note 2 (SPH-L900) and noticed these antenna ports (I think that's what they are) They are covered by a thin plastic layer that looks like I could probably pierce it with something, but I haven't tried it because I am not an idiot. One of them is labeled "R1" and the other "G"
I have heard that unless you buy the right external antenna, that use of these ports can hurt your phone, potentially disabling the internal antenna. That being said, I was looking for an antenna case for the note 2 that will increase my signal, or bring those ports outside the phone so I don't need to remove the battery when using the external antenna (And removing the ext. antenna will still have the internal one enabled.) I looked and searched the fourms, and could not find information on an antenna case for the note 2. If any of you know where I can find one, or possibly customly order one that would be appreciated.
Thanks.
