Title: Omega GSM Antenna
Post by: grain.ben on 21 July 2013, 14:46:34
We all know that the short stubby aerial on some saloons is the GSM antenna. The cable runs from the roof, down the C pillar and down the drivers side of the car and is terminated behind the kick panel. Does anyone know what the terminated GSM antenna PLUG is called?? as I am wanting an adaptor that runs from this terminated plug to an FME male/female plug for my handsfree unit and about 1 to 2 meters long to run behind the dash to the pass side where the pre-wired telephone loom plug is.

Also, can anyone confirm that this picture is an FME male/female?? plug. This is the plug that plugs into the Nokia 610 CarKit brains box.

Difficult to tell from the pic, fairly sure the 50 ohm plugs at the kick panel are SMA or SME, but someone will need to confirm.

Ok thanks, ill wait for a few more responses yet, I just haven't had time to remove my kick panel to have a look myself, but a picture of this terminated plug from anyone would be a bonus  :y

Done some research, and the picture above is an FME Female plug, so I just need to know what the terminated gsm plug is.

thats a female std phone plug the antenna lead should be a std male fitting,if not the pugs are about £1.75 each.

The plug in the footwell is not something I've ever come across before. You might need the section of loom that goes from the footwell up into the radio cage to turn it into something useful. Not sure what the telematics box normally has on it. SMA rings a bell.

If you need some FME connectors, male, female, couplers boots etc, give me shout as Ive got some kicking around from the old Dolphin Tetra days, may have some adapters as well but they wont be to SMA though as dont use them. Your need a 50 ohm Crimp Tool though.  ;)

You can buy the genuine GM adapter cable to patch from the kickpanel connector to the HF car kit:-

93160392

£16.00 the last time I bought one.

Autoloeads also do the same cable but I can't find the part number at the moment.

Cheers guys for the responces. I shall investigate the gm part above and i shall consult my autoleads catalogue when i can find it too :y

Vxl v6, do you know how long this adaptor is?  :y
Title: Re: Omega GSM Antenna
Post by: VXL V6 on 23 July 2013, 00:16:29
It's long enough to get from the drivers kickpanel to the passenger side of the centre console IIRC (meets up with a standard length Nokia or Bury cradle antenna tail).

Might be worth checking the kickpanel first for the vacant connector as the cars I've seen lately have been equipped with a Elite GSM / GPS combi antenna whereas i'm not 100% if the single GSM twig antenna coax terminates on the kick panel connector as it's been a long time since I looked at one!

Thanks very much for the info, when i get chance at the weekend ill take the kick panel off and have a look, then i shall report back  :y

** UPDATE **

Just been and had the kick panel off and I was faced with this! 2 wires, a black one with a female FME connector on it and a grey one which is plugged into another grey wire via an un-specified connector and runs up into the dash, which one is which??

One of them has the be the GSM cable and the other, I'm assuming the GPS cable, but I don't have GPS unless the short stubby antenna on my roof does both??

The Grey Looks like its 75 Ohm, so I reckon thats for your FM, rear Amp and Window feed.

Post by: Vega on 27 July 2013, 10:52:37
You do not have a gps aerial only a gsm aerial.
This black cable is used for a gsm.
The grey cable is for the radio

I thought the FM aerial HAD to run down the PASSENGER side of the vehicle? Quote me if I'm wrong  :-\

I have a feeling mine does, but I might be wrong. It's been a while since I looked. IIRC, I have 2 unused cables that come up to behind the driver's kick panel. Easy way to tell which is which is to find them around the rear seat area (under the little armrest panel). The GSM one goes up past the seat back, up the rear pillar behind the trim and across to the antenna.

Scrap the information I gave you, that's only for the GPS and GSM combination antenna and loom

Ok daddy  ;)

Thought it was, but I also thought they had to run down the pas side.

Ok nice one.

So, the black one it is, so I just need an FME coupler and some more wire then.

Im just going to pop out and have a look in the boot area for this wire to confirm my suspicions  :)
Title: Re: Omega GSM Antenna
Post by: grain.ben on 27 July 2013, 11:44:06
Right all sorted, just been out to the boot and found this, the grey FM wire and where my thumb and index finger are, the GSM cable wrapped up in some sort of foamy tape and they obviously run down the Drivers side, much to my surprise  ::) .

So, just need to get an FME coupler and some more cable to run behind the dash onto the pas side. Cheers all.  :)

Just one more question, I promise  ::)

Whats the frequency of the antenna? is it GSM 800mhz? I will be putting in a PAYG Voda sim in the unit, so will obviously run 2G.
Title: Re: Omega GSM Antenna
Post by: RobG on 27 July 2013, 12:01:51
900mHz
Title: Re: Omega GSM Antenna

900mHz

I'm done on this thread now haha  ;)

Post by: zirk on 27 July 2013, 12:12:02
As Rob says its a 1/4 Wave for 900 Mhz, but you probably find it will run quiet happy as a 1/2 Wave at 1800 Mhz.

2G (The Generation Spec) can be 900 or !800 Mhz, so your probably find the Nokia Kit will run all Networks, with the exception of Three.

As said a few posts up, if you get stuck with the FME plugs and bits, Ive got some kicking around, I could always make up an extension cable for you.

I might just take you up on that offer but it wont be until ive come back off my holidays in a few weeks time. I need a male to male coupler and a cable, approx. 2m long with female fme's on either end  :y

Why the coupler, think you just need 2m coax with FME Female and Male on each end.

And replied, just check that the footwell plug is FME and not SMA as they look very similar, your Nokia Kit should have a FME Male input so that footwell plug should screw in the back of it if its an FME.  :y
