where is the arial on a Cerbera
Discussion
I thought (but could be mistaken) that there was a unit behind the LHS rear seat that acted as an aerial.
Something like what BMW used in the mid-90s.
If it's any help I do know alinton off here managed the impossible and improved the radio reception on his car so a PM to him might be worthwhile.

On mine and I believe a lot of cars the aerial lead runs along the top of the transmission tunnel and joins to nothing. There used to be a thread on here about improving reception where it is now God only knows. You can as I have done extend the lead through into the boot and connect it to an ordinary telescopic aerial, you can then slide this up the drivers side roof pillar fully extended (there is enough room). I put mine in a length of garden hose before sliding it up to make sure it didn't retract and to prevent it earthig out on the roll cage. Remember to provide it with an earth to the chassis though.
On my 97 4.2 it's included in the wiring loom, I think along the front dash. I replaced the FM one with a powered stuck on windscreen type, stuck to the bodywork inside the boot above the tank. Works a lot better than the standard although not perfect.
I then realised my head unit could take a dab add-on unit thats been placed next to the ECU in the passenger footwell. That aerial is again a stuck on type this time stuck to the front bulkhead passenger side.
Both work pretty well, although not perfect, but I wanted to keep the smooth lines on the outside of the car.

Just thought I would report back on my latest findings...I have spent 2 days tryng to solve this problem and although its better its still rubbish compared to other steel cars.
this is what I tried that DID NOT WORK so I might save you some time and money.
1 Windscreen aerial with amplifier ....no difference possibly worse.
2 windscreen aerial in different locations...still no good.
3 Rewired pos and neg supply direct to battery ..no change
4 rewired to seperate battery inside car ...still no good.
fitted suppessors to pos and ign sw feeds...no difference.
5 different head unit (Kenwood) no better
the fact that the Interference is still there when the engine is running EVEN WITH A SEPERATE BATTERY would indicate to me that problemis with airborne interference and not withn the wiring.
The only thing that has worked and improved the situation mildly is fitting the aerial in the boot, rewiring the aerial with UHF satelite screened cable (two screens)anearthing the screen at both ends.
any more suggestions / solutions would be welcome.

Email carl on www.tvruk.tv or ring him on 0772 072 3407 the best guy too sort it out. alan
I can't get to sleep 
so I dug this out.......
1) Get a replacement telescopic aerial from Halfords. Unless you can find one with a suitable length of lead you'll need an extension co-ax cable (2m) which they also sell. This will cost you about £ 25-30 with VAT.
2) Open boot, remove Velcro cover obstructing all black boxes and CD player and lay it in the bottom of the boot.
3) Remove the CD player, there are two screws on either side of it. Also un-Velcro all electronics carefully and leave them dangling in the boot.
4) Remove the rear 'cubby hole'. This is retained by a single wing nut which is accessible from the boot above the fuel tank, behind the CD player, black boxes etc.
5) After removing wing nut, crawl into passenger compartment, and carefully pull forward the cubbyhole which will leave the opening you’ll need to drill a hole through later.
6) Then remove passengers’ footwell under dash cover and feel lead on drivers side of radio.
7) With small slotted screwdrivers, pry into the vertical holes around the radio. Also there are tabs under the radio that need to be flattened for the Head Unit to come out.
8) Pull out the head unit and replace the existing aerial plug with the new lead.
9) Run the new aerial cable down the curved passenger 'grab handle' (there is a wiring harness under there already) and feed the cable under the PASSENGERS SIDE OF THE transmission tunnel padding until you reach the cubby hole area between the rear seats. This will keep the aerial cable as far as possible from the wiring harness under the transmission cover.
10) Drill a hole, approx 8-10mm, suitable for passing the co-ax lead through from the car to the boot, JUST BELOW THE WINGNUT HOLE. You'd have to be trying pretty hard to drill through anything important by mistake!
11) Cover the base of the new aerial, the tip, and the ferrite bead on it with Electrical Tape to keep it from rattling when inserted in the car.
12) Then feed the new aerial lead through the hole from the boot to the passengers compartment and connect to the aerial lead from the radio.
13) Place the aerial lead under the metal rod across the cubbyhole opening, and then Cover with Electrical Tape to insure clean connection.
14) Take the aerial lead and route it across the upper lip of the boot/window junction. Then extend the new aerial and feed it up the drivers side B pillar which is fairly easy. It's quite a big void with only the roll cage tube in there.
My aerial seems to have wedged itself in place and doesn't rattle. I reckon the end of the antenna is up near the drivers head.
That's all there is to it! One dealer said they fitted an aerial as I've just described but laid it on top of the black boxes above the fuel tank. I tried that first of all but didn't notice any difference.

Exactly - and perfect reception
