Hi,
Have a Kaiser on the way and want to have an external GPS antenna and an external phone antenna ready to go when it gets here.
But I can't find anywhere what types of antenna sockets the Kaiser has for these two antennas?
Does anyone know???
Thanks.
Great forum, by the way!
As far as i can see it only has a socket for a GPS antenna so i assume this would probably act as both although not sure
you can get the official antenna from expansys

I can confirm spooki37 says, from what I can tell, there is only one port. It is located the rubber GPS stamp that is on the back of the device. eBay has them shipping to the US for about $15 - $20 non-oem from China.
When I remove the battery cover, it sure looks like there are two jacks. I too thought the other must be for external Cellular antenna.
So does anyone know what the 2nd port is used for?
Whatever you do dont use the second port because it will damage your phone. I plugged an external antenna into my original phone and when I removed it the phone had no signal at all. The only way to get any signal was to use an external antenna after that.
That second port is an antenna port but htc doesnt support any antenna for it and is supposed to be used for debugging purposes only.
I use an external antenna all the time with mine... (TyTN II / Kaiser) works ok.. not great, but gets me one more bar, and seems to hold the signal better in a low signal area.
I use this adapter:

with one of their antennas.
I don't have any problems with signal after I disconnect it, but i'm pretty careful with connect/disconnect, and I cradle it while connected. I bet a little torque would probably damage the connection which would probably damage the internal antenna connection as well.
So you remove the battery cover and plug that antenna into the smaller of the two ports? Ive damaged 2 phones trying external antennas and so have others. This one is a htc titan http://pdaphonehome.com/forums/ppc-6800-xv6800/96140-phone-signal-horrible.html and theres more reports like this one.

I usually just pull my battery cover off, carefully seat the antenna into the port on the left, and then cradle the the thing.
I've done this with this phone, a moto blackjack, and at least two other moto phones in the past, and never had an issue. Again, though... I've pretty much ALWAYS immobilized the phone while it's got the antenna jack plugged in. I actually try to do the same when USB is in too... the boards inside these tiny devices are too thin and the amount of torque you can apply accidentally is quite high... best to be safe... but I get intermittent signal where I use it most frequently, so I accept the risk.
Thanks!

That's exactly the answer I needed - thanks heaps!
So obviously it takes the some patch lead as the Tytn. In that case I'll just get a Tytn patch lead off ebay and hope for the best.
The owner's manual I found for the Tytn says you can use the antenna plug, so they obviously thought it was safe then, but maybe hid it on this model because of a few reported breakages. I'm going to use mine only occasionally and in a cradle, so I hope I'll be OK if I'm very careful. Maybe I'll never end up using it given the risk...
Another option would be one of those universal antenna leads. They clip on the back of the phone and work by an induction coil. Their performance is very variable - mine works OK (+1 bar) on a friend's phone, but seems to make no difference on my phone.
I want to add this as well: plugging in an external antenna can damage your phone. I have plugged a wilson antenna into my 8925 and now my reception is extremely poor... I am not sure of the cause, or how to fix it.. just hope to help people avoid this.
We have the 8925 here at our office and have found that the port on the right side is for GPS only. The left port is for cellular reception.
We have not damaged the phone that we have here and have had the 8925 for about 6 months.
There are a few issues with using external antennas:
First of all, the connector must be properly sized for the phone.
With some device/connector combinations it is normal for the connector to appear to not be fully seated. If you try to force the connector on further you can do permanent damage to the phone.
In the phone there is a tiny mechanical switch that gets tripped when you plug the external antenna in. This physically disconnects the internal antenna and connects the phone's radio to the antenna port. Sometimes this switch gets stuck in the port position, so you get poor performance when you disconnect the external antenna. This is especially common with CDMA Motorola V3 models.

any body uses a wifi external antenna????
How hard is it to fix this "switch"? I have a kaiser that will only work with an external antenna after using one. Port isnt damaged as far as I can tell and ive never had problems with external antennas with other phones.

I've never actually had this happen to any of my phones, so I don't know how hard it is to fix. If the external antenna was forced onto the connector you may have to send the phone in for service to have the port replaced. The only other thing I can think of is to put a small amount of contact cleaner on the port itself, the gently work it in with the external antenna connector. This may loosen the switch and let it return to the internal antenna position if this is your problem. In all likelihood I'd say that a warranty exchange is probably your best bet.

has anyone notised a 3rd port? its between the camera and the speaker and slightly higer than the other 2 I bet that ones for wifi at 1st glance I thought it was a screw.
I don't understand why the port were designed in the first place when things seem to be such a useless purpose ...etc
comes with INTERNAL GPS ... so why the need for EXTERNAL ??? and if you do need to use it ... it is delicate and chances are, you're screwed and damage it !!
so why bother designed it ?? <scratching head> !!!
External antennae that are properly sized for the operational wavelength will always have higher effective gain than any built-on antenna that is capable of fitting on a typical handheld device.
The External GPS antenna has 27 dB Gain (typical)... I cannot find specifications for the internal antenna on our Kaiser's, but I am willing to bet they are probably at best a unity antenna, maybe 3db on the good side.
That means you will recieve SIGNIFICANTLY signal strength and more satellites when you are doing anything involving GPS, and weather, antenna position, and all standard environmental factors will have significantly less effect on your GPS activities.
The same goes for an external antenna for the cellular portion. The internal radio boosts power output when it has degraded reception which means when you're in a poor reception area, you burn more battery doing the same things you typically do.
A "gain" vehicular antenna directly connected to your phone will increase battery life when using wireless connections to the cellular network, as well as provide you good reception where you would otherwise have poor to none.
Of course, if you live in an urban area, this is probably of no use to you... but in a built up area with many large buildings around, you may not have as good GPS resolution and reception as you could with an external antenna..
*
The primary reason they put these on there is moreso for diagnostic purposes probably... hook it up to a freq counter and/or spectrum analyzer and you can tell that the radio is actually putting out what frequency and it's strength as well. Without those, there's no external way to ensure transmission is occuring without possible interference.

I've examined this very closely under a bright light, and I have concluded that it is a screw with a Torx head.
Hello everyone, I have a couple of questions to ask all of you great phone gurus
**If this is the wrong forum for this sort of thread, I apologize in advance**
Basically I have ruined the USB connection on my Touch Cruise. I am wanting to know if there is any way I can access my files on the phone by having it connected to my wireless network at home (ie a program or something I can run on my PC.) Reason I ask is I am trying to edit the HTC weather Plugin to show my location (Lebanon, OH, USA) and it is quite hard/impossible to do using the phone alone.
Second question is, is it possible to replace a damaged USB connector? I know it is probably ruined but I figure it might be worth a try. I had attempted to hook up my front USB header on my motherboard, but plugged them in backwards. I managed to salvage the phone by removing the actual USB piece from the phone and pulling the wires out. Luckily I am still able to use the phone (nothing else besides the USB connector is messed up) by purchasing an external battery charger + battery.
I know these are probably both a shot in the dark but any help anyone could provide would be GREATLY appreciated.
You can sync via bluetooth if you have it on your computer, or wifi search in google for that (ex: http://wifi.aximsite.com/sync.html)
I tought replace it will be very hard .
just out of curiosity could you please give us some screenshots as i'm having a real hard time understanding what you did and how it looks now? ^^
using bluetooth will help and maybe a card reader + microSD might speed things up. find a good file manager for WinMO
i doubt that there is any way to acces phones files through wireles so bluetooth is the only wireless (and supported) way
I don't have a camera currently but just look at your USB connection on your phone then imagine that there is absolutely nothing in it. It is just an empty 'rectangle'. No wires or the little horizontal piece that normally sits in there. Just an empty 'rectangle.'
Thanks for the replies. I am trying the wireless sync now.
Thanks a bunch
Can someone telm me whats on picture1 its looking like some hidden usb port or something else and what is on picture2,look like some button,dont know.
are the first point of contact and the second antenna I believe
the first pic are from contact pins from the phone's internal gsm antenna. the second is a connector for external gps antenna.
Hi there!
I'm trying to replace the mini-USB charger port in my hd2 but havent had the chance to open the phone yet and trying to buy components. which part do I need for it? a 5-pin or 8-pin?
I am currently awaiting for my torx screw drivers to come through the post and preparing all the parts I need. So far, I have not found any site that has showed how to fix this on the HD2.
My plan is to purchase the mini-USB port, open my phone up and solder in the new port. Has anyone attempted this yet successfully?
I also posted a response to this in the "Arrow
[FAQ] Q&A: How? Where? what? Ideas? [New Users?]" thread you posted this in. The HD2 has a 5 pin micro USB port, it is soldered to the bottom of the main board. I have read post of people having success with replacing it and I have also read post saying it is not just a easy task unless you are good at soldering. Good luck.
thanks! (my apologies for double posting). from what i've read so far on people trying to replace these parts on the internet, it's a lot easier if you used a dremel to cut off the rear shielding of some sort.
i think my screen needs replacing along the way but i wanna get the charging port working first
off to order some parts off ebay now
In hackaday there's an article on replacing usb ports.. I cant post it but I can send it over by PM if you want
By the way, do you mind posting some photos of the HTC HD2' usb port when you open it? I never opened mine but I need to change the usb port too.. so any intel I can get in advance.. the better ;-)
Hi all, new to XDa so go easy on me here...
Just. Got a smj327p sprint phone
Where I live I get very poor 4g coverage roughly -105dbm on band 41
What I am trying to do is connect an external antenna
The phone has a mhc705 connector labeled r1 which I'd love to make use of
I have a patch lead from my S4 days, This is a ms705 to FME
The cable fits the port but I do not think the center pin is making contact as I do not get any signal changes whatsoever, doesn't appear long enough
I am trying to avoid using a passive patch
can someone recommend a correct cable for this phone?
Thanks in advance
Hey Jer1981,
I'm in the same condition, pls update if you find a solution to plug an external antenna to the J3.
I share here a reply from some antenna makers in New Zealand: "The port on the J3 is more of a 'test port' than a usable antenna port. The port is smaller and more delicate than the one in the link, so much so it's designed for use in a 'laboratory environment' only. I can get the fitting to work with it, but it must be held in place and costs more."
I'm thinking of getting a 3G mobile wifi device from huawei with external antenna port...
Hi what cable are you using? for this as mine doesn't appear to get a connection at all
