Followed Marcs footsteps and installed my UHF yesterday.
Some slight differences though.
First of all, I used an ICOM IC-440N because I like ICOM better
This is the same style UHF with remote speaker/microphone and hidden away main unit.
I also used a shorter and flexible 4db antenna from Benelec. I mounted it with a Z bracket from Dick Smith using the existing bolt on the passenger side. Also added the nyloc nut to make sure it stays there. The gap in my GC is very small and the bracket required some creative bending to make it fit but now it does fit nicely with nothing to spare. Also Added some tape to the bracket to protect the paint.
Getting the antenna cable through the firewall was a challenge. Was easy enough to find the big blanking grommet except that on my Overland that is already used for almost a dozen cable bundles and cables. No way I could remove that and very difficult to find some space between the cables to get through.
Finally managed to punch a hole and push the antenna cable through.
I didn't fancy removing the center console panels to get to the cigarette lighter so I took power from the easily accessible pole provided for jump starting at the drivers side of the engine compartment. just taped the wire to the antenna cable and pulled it through the firewall.
This was a very easy way to get clean power direct from the battery.
The main unit was then tucked away behind the carpet on the passenger side. There is some sort of rubbery isolation to the firewall so the main unit cannot move and the rubber prevents rattling.
I brought the mic extension out on the passenger side and fixed it with double sided tape to the side trim. The speaker/mic is fixed to the right of the front console also with double sided tape.
Complete installation took about 4h. Most of it was spent removing the trim below the glovebox and getting through the firewall.
