got some feedback from wilsonelectronics.com

From there support email ...

..."Because that model isn’t a very high production model we haven’t had any word from our engineers about the availability of an adapter for that Pocket PC."...

..."I can however judge strictly from the picture that you sent to us that the connector on the attached .pdf file looks very similar to one used on a previous phone we have an adapter for. That adapter part number is 356808 although we no longer recommend that adapter for that phone due to us running into cases where that phone had a very weak port causing it to break. When this happens the phone no longer gets signal. I can’t guarantee at all that the adapter will fit into your phone or that it won’t cause damage to that adapter port since we have no test results on it. Because of this you’re inserting that adapter at your own risk"....

I spoke to a local Auckland supplier ( http://www.mastec.co.nz/ ).

There comments were "the connector was a funny looking thing, and not standard in the industry"

My gut feeling is that the risk of using an external antennna on the Jas Jar may be to great. Unless a specific adapter is built exactly to HTC Universal external GSM connector specifications (Refer part number quoted in this thread). I dont recommend using a adapter that is generic, it must be approved by the HTC company, and I dont think one exists..Well so far.

The connector was described to be weak by the well known "WilsonElectronics". And if the connector breaks the device is trash. A little thing like that breaks and the whole device cant get a signal, go figure....

I have not been able to find yet the offical HTC forums, were HTC technicans are forum contributors. Have any of you found a forum like this out there on the WWW ?

Other choices are
Wireless repeaters ( see TradeMe.co.nz or http://ctsl.co.nz/ )

Still on the hunt...

Concerning the Jas Jar connector : The JAS JAR connector on the phone is a Amphenol MHC-H196. http://wiki.xda-developers.com/uploads/MHCH196.pdf

I regret to inform you that this is a connector or adapter that we do not carry. Also, the minimum quantities required for Pasternack to build a custom may be out of your target price and quantity. We would require an Order that is large enough to amortize the tooling, so the minimum quantity will be around 10,000 connectors and 12 weeks. Let me know if you want us to pursue a custom connector or adapter.

NEWS NEWS....Posted first at : http://forum.xda-developers.com/viewtopic.php?p=272441#272441

More Detail at : http://www.boatersphone.com/Adapters.asp , and http://www.primecellular.com/index.asp?PageAction=VIEWPROD&ProdID=109

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. '...

ANY BODY HAVE ONE OF THESE ON ANOTHER PHONE TYPE, please comment ?

Not sure where you would stick the velcro part on the Jas Jar, not the best fashion statement I think ! O well beggers and choosers thing !!

Mate you've given us hope. Like yourself I have been scouring the forums for a solution and this is the best so far. I sent an email to Boatersphone and got the following reply:

"The adapter for the i-Mate JasJar has a connector which inserts into the antenna socket on the phone and terminates in an FME Female connection, ready to connect to one of our antennae.

The cost for this adapter is UK £15.

The Mini-Mag Mount Antenna (with a 3G/Multiband 850/900/1800/1900/2100MHz whip) cost UK £30 with 2.3m of cable, or UK £35 with 4m of cable.

I am unsure about postage costs to NZ, but if you are interested in ordering then I can obtain those for you."

I have replied asking for a photo and if the adapter will fit both sockets.

Will post more when I have more.

He is advocating the use of Nokia adapters, I hope he has done his testing correctly. Taking into account Wilson Electronics comments on the connector.

Remeber be careful, USA has 1900 MHZ, and UK, Asia , Aussie have 1800 MHZ for GSM.

There is also the velcro patch adapter if the plug in one fails.

keep the info coming.

Not only 1800MHz for GSM, but also 2100 MHz for UMTS...
