Would attaching the wire to the bodywork be feasible to extend the range i.e. using the whole body as the antenna? Question

The body is connected to battery negative - ie earth. So that wouldn't be good at all for improving reception Wink

Actually there are ways of using the body as an antenna, but it's not a very good shape or size for sending or receiving radio signals at the frequencies alarm remotes operate at. Just getting the antenna out of the big metal box is sufficient - which is why most aftermarket alarms have their antenna in the engine bay (which is effectively open at the front and bottom)

Just thought I would do a quick write up to help other folk.

Step 1 - Locate Cobra Alarm Interface (the location is in the front kick panels - which I will let yous to work out yourself)
Step 2 - You will see a Black or a Red wire tagged Antenna
Step 3 - Use a 20AWG wire (I bought it from Maplins)
Step 4 - Solder one end to the Black Antenna wire (or Red) from the Cobra Interface and then insulate (I used shrink wrap)
Step 5 - Run the wire all the way up to the A Pillar
Step 6 - Shave 2mm of the wire so that the copper is exposed
Step 7 - Either tuck the wire behind the rubber trim with the copper bit exposed (what I did - and no you cant see it) or behind the plastic trim and place the wire so the copper bit touches the glass (what I did initially) both locations gave me good results.

NOTE:- The Antenna wire should not touch the body

Hope this helps.

I have attached a photo to help (just pulled the copper bit out a bit to show in the picture)

I'm new to the forum and just got a 2004 3.2 lwb. The whole key fob range thing was a pita so after one days ownership and googling I found this forum.

I extended my antenna up the a pillar then along under the headlining by just pulling back the door rubbers. I put about 10 foot of extension in and made a coiled loop around my fingers a few times which I pushed into the area above the rear seats.

Remote now works from about 20 foot away like a normal car should.

I followed the latter solution above and it works a treat! I used the second fix as I figured it was better to have plenty of wire. Just in case I had to go for the initial suggestion. Simple fix to an extremely frustrating short coming of these vehicles. Brilliant guys! Thanks.

Followed this easy peasy mod and added great range to the fob.
