Got a question I’d like answering before I go sink a load of money into a Scorpion SA680 to find I’ve wasted it.
Here’s my current installation on my MK4 Ford Mondeo. It’s a Little Tarheel II with 72” whip on a Diamond K400 on the hatchback. (Not my first choice of installation location but more will be explained below)http://i300.photobucket.com/albums/nn9/computershack/Amateur%20stuff/Icom%207000%20install/20120811_202650.jpg
On my previous car the same antenna was mounted on the middle of the roof via a 3/8 fixed mount. This isn’t possible on this car because the roof sheet metal is too thin and they’ve put some sound deadening tar on the underside. The VHF antenna is installed on the only part of the roof I could see wasn’t covered in this without removing the headlining. To remove the headlining is half a day's work due to airbags in the side pillars and removing the tar stuff risks blistering the paint on the roof.
If you look at the rear quarter you’ll see a panel gap going from half way up the rear arch towards the rear light cluster and that is all plastic as its the rear bumper and there’s a gap about 4” deep between the bumper and the actual metal bodywork behind it. The tailgate from the horizontal line above the Ford logo down is all plastic so bolting it to the tailgate as G7DIE has done is out of the question. The rear quarter panel is double skinned with a gap between each skin of about an inch and a half so that makes putting a Breedlove body mount on the side of the rear quarter basically impossible as I can’t get to the back face of the outer panel.
The problem I have is that despite being sat here with a hole cutter and no hesitation to use it, no matter what I want to do the only mounting option I can see for a SA680 is a tow hitch mount. My concern about this is that its probably the worst place possible for efficiency.
This is the tow bar I’ve currently got fitted. The long bar bolts directly to the body in place of the rear crumple bar. It bolts to the body shell by eight M10 bolts.http://thumbs1.ebaystatic.com/d/l225/m/mokGhTzvmSxPbrbBv2PidZw.jpg
I can possibly double skin the roof to support a fixed mount for the Little Tarheel II where the VHF antenna is located if I could remove enough of this tar like stuff they’ve painted on the underside. An alternative for the Tarheel is to make up a metal bracket to support it fixed to come out of the gap between the tailgate and the roof.
Given my main bands of interest are 20-10m with maybe a bit of 40m, taking into account losses from using a tow hitch mount would a SA680 on a tow hitch mount be better than my Little Tarheel II wth 72" whip mounted on the roof?
If you’ve got any suggestions I’d love to hear them because I’m just coming up with a blank as everywhere I look there’s obstacles in the way.
Modern cars are definitely becoming a lot harder to install antennas on even if you’re willing to drill holes.
