[Galaxy S II General] unsquashable:
For the curious full disclosure

Guys: :silly:

I correct this post as I trusted a previous one regarding the right connector (I personally ordered 2 cables and realized I had ordered the wrong one). Luckily the wrong connector just will not fit

The correct connector is a Hirose but model MS-162 and not the MS-147. :silly:

Messing with tiny connectors with just a wire in such a delicate piece of electronic equipment is to say the least dangerous......

(some background I am an electronic engineer and did my fair share of electronics fiddling as a younger man..)

The connector most of you refer is actually a coaxial switch manufactured by Hirose Electronics, as correctly stated an MS-147 SO SORRY incorrect previous model, the

correct connector is an MS-162

(smaller even than the MS-147). The purpose as stated in its data sheet is the following QUOTE

"The ultra-small MS-147 coaxial switch was developed for the portable terminal interface and for inspection of microwave boards (substrates) (DC – 6GHz) used at high frequencies. Designed to be used as the interface antenna connection for portable terminal devices as well as circuit testing on microwave boards (DC to 10GHz) the coaxial switch offers high performace, low loss, extremely high durability and reliability, in a small and lightweight package.

To respond to the development of portable terminal technologies and popularization of high frequency applications – up to 6GHz – this switch features low loss, low profile, and light weight.

The switch circuit is designed so that the NC terminal is connected to the C terminal without a plug mated. Mating with a plug opens this

connection.

END QUOTE ;)

Reading where it states to be used for high frecuencies another acronym comes to mind KISS (Keep It Short Stupid), every high frequency design or fiddling involves short cabling, otherwise trouble comes (wavelength and distance involved), so it is not recomended to use just a wire for these purposes.

On other hand the connector is guaranteed by Hirose as able to withstand 12.000 mechanical operations !!!!!! more than enough, PROVIDED YOU USE THE RIGHT MATING CONNECTOR EITHER

MS-147MS-162-C(LP)-1 THE ONE USED BY THE AUSTRALIAN PROVIDER MENTIONED IN PAGE 2 WITH A CABLE AND FME CONNECTOR

OR MS-147MS-162-HRMJ-1 DIRECTLY MATING TO AN SMA FEMALE CONNECTOR

I would not suggest for the faint of heart or unexperienced to try to do your own cable or actually CHANGE the connector once it has been destroyed internally by inserting wires, but it can certainly be done with the right skillset, magnifying glass and special thin point solder iron.

Full details and specs can be found in the data sheet available at MOUSER ELECTRONICS, as far as I know the most complete stock in electronics components available on the web (no connection at all..) search in Mouser for Hirose MS-147MS-162

Complete data sheet in e35801505e35802083-32633.pdf at hirose japan (sorry can not paste the link)

Conclusion in order of possiblities:

1.- If you already destroyed the switch connector with a wire or wrong connector you can actually buy the part at Mouser and have it replaced, strongly suggest a cell repair shop as soldering tiny parts skills is definitely a prequisite. With this solution your phone is stock again.

2.- If you do not want to go thru that trouble I guess the pin and push preheated solder in the hole will create a permanent connection for the internal antenna to work correctly (no wire since KISS).

3.- If you have not yet destroyed the switch either get the cable from the Aussie vendor or wpsantennas (model WA-1071) in the US, and use whatever antenna you feel like connecting the FME to a yagi, omnidirectional or whatever one you have (eventually a car antenna if equipped with FME conector)

4.- If able, go buy one of the mating connectors from Mouser, use the right 50 Ohm cable and connect to whatever antenna you have, I personally will do a cable for my BMW equipped with its own antenna connector.

Hope this clarifies a bit better

p.s. FME and SMA are normal antenna connectors, will find several vendors offering antennas with either one
