[Q] How have you solved the antenna grip issue? - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Recenly moved from a TP2 to the HD2 and am experiencing some antenna (signal) issues that I hadn't with the TP2
I know there are threads about a 'killing grip', but I haven't yet found a solution or at least a partial help.
Holding in RIGHT HAND:
Signal drops by at least 2, usually 3 bars (GPRS)
Holding in LEFT HAND:
Signal drops by 1-2 bars, but not usually lower (GPRS)
I have tried changing grips but unless I hold he phone above the antenna nothing changes, and with this grip its difficult to operate one handed
Wifi is uneffected and I haven't been in a HSDPA area to test that, but I pressume it will be effected similarly.
Has anyone found that using certain cases or full body skins help the situation? or is it simply that our hands are blocking the signal and therefore no case/skin will help?

not aware of any signal issues but I do have my phone in a silicon case that it came with. I'd recommend using a silicon case just for the fact that if you place your phone face down, it keeps the screen up off of the surface thus saving it from getting scratched up.

8525 Accessory Antenna Recommendations

I recently moved into an area with poor AT&T coverage even though their coverage map shows that I'm in "Best" coverage. Almost all of my calls break up and many drop unless I'm outside near a major road, which is obviously inconvenient. Has anyone has success using an external antenna though the port on the back of the phone near the camera lens? I would prefer it to be a solid antenna not a flexible one that hangs down off the phone and of course the smaller the better.
As a side note, I attempted to use BandSwitcher and Edge with 2 bars is the best signal I get in my house and still is a very poor connection. I do not want to purchase an expensive hard wired signal amp and antenna just for home use.
Thanks in advance,
Justin

Just an FYI, I bought a RadioShack universal antenna adapter, and it killed my cell phone. PDA still works, but I get no reception at all now. oing to have to send it in for repairs.
i.e. be carefull with external antennas
I did the same thing, bought the Radio Shack antenna, plugged it into my 8525, the phone lost all reception and I had to replace it.
You've been warned!
Hermes external antenna
Search eBay for the ARC Freedom antenna (also need adapter). I bought one and went from 1-2 bars & dropping calls to 3-4 bars and no more dropped calls. I'm not endorsing this product, its just the only one I've come across and so far it works pretty good.

Wifi signal affected by phone case

I am sure most people on here would have noticed that the WiFi signal on the htc amaze is drastically affected by the use of a phone case...
This was a dreaded problem for me up until now...I found a way to boost my WiFi signal without sacrificing protection....
All I did was cut a little piece of aluminium foil and attach it to WiFi antenna located on the inner back panel of the phone.....The antenna is located next to the camera lens....
Once the foil is attached to the antenna, replace the back cover and you should have improved WiFi signal that instant.....Fill free to put on any phone case while surfing the internet at blazing fast speeds using WiFi....
Questions are welcomed if the procedure is not fully understood..
I noticed this when I put a d3o dual case on mine.. can u post pics of what you did?

I have attached a pic of the foil and its location on the back panel of the phone...
Wifi Signal and Cases
Anyone else try this?
Now that sucks, I bought this phone because of the luxurious look and feel (high class build quality). This is like putting rabbit ears on my 65 inch plasma (Ghetto). Just when I thought I was out they pull me back in (into the projects lol).
Don't forget that no one else knows the foil is there except you... A rabbits ear on a 65inches tv can't be hidden..

Haha so true!
that is pretty ghetto but its hidden so if it works i guess you could consider it hardware hacking
Yeah mine is about 5mbs difference

I have the d30 case and I never had a problem with wifi signal... have you ever thought that it was your internet provider or maybe your router?

Perhaps your router is not far from your phone that why... If there are few walls between your phone and router you will notice the problem..
This has nothing to do with internet provider or router..
Try covering the top of your phone when the d30 case is removed and see if your wifi signal drops... If it dosen't then you are too close to your router to notice the problem...
All the fol does is boost your wifi signal .. I have been using it for while and I have consistently got full wifi signal even when there are few walls between my device and the router,,,
Makes a difference, thank you
Bluetooth
I've also notice the same problem with the bluetooth radio. With a gummy cover on (silcone I believe) my moto bluetooth headset SD9-HD doesn't work worth a F*&k but without the cover it's all good.
Which is the BT antenne?
How about cell signal???
This trick reminded me of the old product called cell phone signal booster sticker. Here's a YouTube video http://youtu.be/Elgx7lp7YMc if you are not sure what I'm talking about.
If we can boost cell signal using your method, it would save battery as well (without spending too much money on this sticker). Any thought, guys?
Might be a contact issue, not a "this piece of aluminum foil is a better antenna." I'd posit that the two gold colored contacts are not making a solid electrical connection to the rear cover's antenna contacts and that the aluminum is helping by acting as a shim. But I could be wrong. For those of you with Wi-Fi issues, ever so carefully bend the little gold colored metal contacts on your phone upward to ensure solid contact with the rear of the case.

Well the foil also helps the wifi signal retain its strength... Try covering the back of your phone using your hand and you will see that you loose all wireless signal unless you are close to the router..
Try the same procedure with the foil on and you will see that the wireless signal remains strong regardless of position
Wow, this little piece of aluminum actually works. However, it doesn't work 100% for me. My WiFi signal strength fluctuates quite a bit. But at least I can actually stay connected to my WiFi now.
Thanks. This is a great tip
Edit: this also fixed the problem my amaze had when connecting to my router at work. It would always say connected but data would never be exchanged.

I thought you were punking us. I was hesitant to even try, because I just KNEW this was a joke. But... it really does work!
I have had nothing buy buyers remorse since buying two of these Amaze phones (full retail price at a TMO store) - on a prepaid plan. They give you about 3 nanoseconds to return - and even then charge a $50/phone restocking fee.
Service is very poor in my home - which I knew before I bought. But, I assumed the Wifi calling would circumvent that problem. I was so disappointed with the jitter, stutter, lost packets, and overall piss-poor wifi call quality, that I upgraded my router, and installed a corporate-rated access point. There was some improvement, but nothing that rivaled a good cell call.
Best DL speeds were around 8-9mbps, and very erratic. With the foil, consistently 20mbps! I am completely dumbfounded.
If such poor wifi performance could be remedied by such a simple fix, why on earth does HTC not do this from the get go? It just doesn't make sense.
So, what have you guys done to keep the foil from shifting, or falling out when changing the battery?
OP, I luv you...

Exactly my issue too. Maybe it'll work if we know which antenna it is.

[Q] Anyone else having antenna sensitivity issues?

I switched from a Focus to the Titan about a week ago. I love the Titan, except it seems to me that the antenna sensitivity is pretty poor. Cases in point:
1. On a call on my Titan at the office, I enter a stairwell in the building, and immediately the call drops. With my Focus, I could walk up and down these stairs all day while on a call and never have the call drop.
2. At home, I get very poor coverage. Last night at home my Titan is telling me that there is no network available. I walk over and pick up my wife's Focus and it is showing AT&T network and two bars! I power cycled my Titan hoping that it might re-lock onto the network, but it continued to tell me that no network was available all evening. I was unable to make or receive any calls last evening.
3. Right now, sitting in my desk at work, my Titan is bouncing between 2-3 bars. My Focus, sitting in the same spot would always show 4-5 bars. When I pick up my Titan, the signal strength display drops to one bar.
I really, really like this phone, but if this is the indication of the signal strength that I can expect, I am going to have to return it. Anyone else having this problem?
OK, I may have answered my own question. After posting, I saw this post:
http://forum.xda-developers.com/showpost.php?p=18523952&postcount=12
I opened the case on my Titan, contacts looked fine. But when I put the phone back together, I squeezed the case very hard at the bottom, and the signal strength indicator immediately went to four bars. Will monitor and see if this takes care of the problem.
Just received my Titan.
The signal is terrible. Sitting right next to my hd7s, the hd7s gets speeds of around 1mbit/sec while the Titan gets connection errors.
Checked the contacts and they are fine
Everywhere I test, the Titan consistently has a weak signal. This is on att in central NY. I wont even compare it to the signal on my Droid with verizon. I absolutely love the phone, but with the signal problems I'm probably going to be returning it

Did you get a new SIM card or are you using your old one. The new micro SIM made a big difference on my Titan. I had a one year old sim from my Focus. My nephew had a 15 month (?) old Sim for an Iphone 3Gs. When I put both in two Titans, mine was had better signal and internet connection. I noticed that Titan uses the micro SIM(saw someone with it), so I got a new micro SIM yesterday. My signal is even better. The internet flies on my phone now.
I'm still using my old sim that I had from the Focus (and earlier). Did you get your micro sim at the AT&T store? I may get one myself.

Yes, I did. Make sure to go to a corporate store. It's free. If you go to a franchise they'll charge $20, I believe.
When I bought my phone online, they sent a new SIM with the phone.
Signal strength and quality seem better since I made my original post. Still not as good as my old Focus, but acceptable.
No issues here! Can text in lifts!

Hello there,
After getting my Titan from AT&T, I saw that the signal was much lower than my iPhone 4.
When I got home, I had no service in the house where I had 1 or 2 bars with the iPhone 4.
I checked the contacts, but they where fine, so I started to make test to find witch of the 2 botthom contacts was the positive of the antenna.
With the phone face down, the faar right contact is the ground of the antenna, because it has continuity with the chassis of the phone.
So the left contact is the one to work with.
I then research on the internet for the lenth of a 850mhz antenna, & I found that it is 9 cm.
I then cut a piece of brass shim half a centimeter wide by 9 centimeter long.
I soldered a small hard copper wire thru the left hole of the cover & soldered it to the inside tab of the back cover, making shure that no solder or wire protrude from the contact. Otherwise you will have problems to close the back cover against the phone.
I then made a pin hole thru one end of my brass shim I had previously cut.
I then turned the cover over & pass the brass shim thru the hard copper wire I just soldered on the inside. I used invisible regular tape to secure the brass shim on the back cover & then proceeded to solder the shim with the hard copper wire as close to the back cover possible. I then tested my invention & I have now 2 bars where I had no service before.
Of course, I Had a Hard Cover shell to cover this installation, but the results are fantastic.
You have to be aware that the phone back cover will be altered in case of warranty, but you can get a replacement cover on Ebay for aprox $36.
Do this at your own risk
You can sand this soldering in order to prevent having difficulties putting a protective skin or cover.
I strip of copper can also be used for this homemade antenna.
You can PM me if you need more help for the installation.
I now have a full functioning HTC Titan that I now have learn to cherish.
By the way, the problem that a lots of people are having with slow downloads, is directly related to tha lack of a good antenna on this phone.
Hope this hep some of you out there.

I found the real problem with signal issues of the Titan.
I had bought a second HTC Titan & I thought of trying the back cover on my first Titan.
The results are astonishing. The back cover was all that was wrong on my device. With the second Titan I purchased from AT&T on the Web, there is no problem with the sigral.
I have now ordered a new cover from Ebay & will try to get a replacement from HTC for my original one that was defective.
I really think there was a bad batch of those back covers for this Titan & we where the unlucky ones to get them.
If you know someone that has no issues with his Titan, try his back cover on your phone.
Hope this help someone.
Good luck.

Signal Issues - resolved!!!!

A quick history - bought a white note on release day, along with speck candyshell case. like with most new phones, had the back off and on several times a day the first few days. broke a few tabs on it, but it lived in its case, no big deal. Well I noticed that data signal in my office was terribly splotchy. I would get signal, drop it, repeat. returned the note after 2 weeks and swapped for another new one.
2nd phone - started with great signal, got worse and worse (also broke a few tabs on the back cover). Well, I was sick of the loose fitting back cover (you could tell even with the case on) so I folded up a receipt and put it between the back of my phone and my case to hold pressure against the back plate.
SIGNAL ISSUES COMPLETELY RESOLVED. I cannot believe how well this phone picks up now. Apparently, the 2 little contact points on the back plate (and the antenna-chip thingy on the backplate) help to aid in signal strength. figured I'd post up to share if anyone has similar issues.
Oh, and I'm kicking myself now because the first phone never had ANY black clipping/crush issues (I started Lost season 1 on Netflix when I got the phone, one episode a night in a pitch black bedroom), and this one has it so bad that you can't even make out dark scenes.

Those contacts you see on the back plate is for NFC not signal Strenth
I know the purpose of the chip in the backplate is for NFC, but it makes a huge difference in signal strength.

I dont think it has anything to do with the cellular antenna

signal level / aluminum cases / antenna location

I've been using an aluminum bumper frame case for a few weeks. It's sleek and stylish, however I've noticed what seems to be weaker signal strength when it's applied. I was recently experiencing outages in my area, I thought these issues may be related. After removing the case signal indicator & dbm is more consistent & higher. Also ping / latency times are lower.
I am wondering if anyone's experienced anything simular with other cases or aluminum styles? Could such a thin frame case obstruct the signal?
Also does anyone know where the antenna is located in the Xperia Z Ultra? I searched, but was unable to locate accurate info.
The Wi-Fi Tx/Rx antenna and GPS antenna is located at the top of the unit (middle right).
