Y22man may be interested in that there is plenty of room behind the door on the rear door hinge post to run an antenna cable. When I use my mag mount in my Ex I use a Yaesu FT-51 laying in the Ex cup holder. The antenna wire runs between the driver's seat and the floor consol, behind the driver's seat to the rear door hinge post, up the post, out to the roof, and on to the mag mount. This is, obviously, a temporary use setup. If Y22man wanted a more permanant set up he could install the radio on the bottom of the dash or on the floor over the tranny in front of the center floor consol. Run the antenna wire under the carpet to the door location I mentioned and on to the mag mount. Or, to the Diamond K-9000 antenna mount. He could mount the K-9000 to the luggage rack on the top. Either on the side or the center of a rack bow.
I have found that it is easier to run the antenna wire, on a permanent install, under the carpet by first removing the driver's seat. Making sure the wire is located so as not to be under the seat tracks when the seat is reinstalled.
I use grey cloth tape to secure the antenna wire to the door post.
I suppose one could run the antenna wire behind the dash, up the A pillar, under the ceiling liner to a hole drilled in the roof. But I am not wild about drilling holes in the roof of my vehicles.
This is why I ran the antenna wire behind the dash, down the kick panel to the left of the E brake, drilled a hole in the floor (I may have run the wire under the door threshold to the rear of the cab before going through the flor under the cab. It has been awhile since I did the install and I am not quite sure.), ran the antenna wire under the cab, to the back of the cab, between the cab and the bed, up to the lumber racks and the K-9000.
It seems as though the K-9000 must be grounded through it's own body to the truck through the lumber rack because I get good TX and RX.
Here is how I mounted the radio behind the knee panel under the steering wheel.
If you look at the image in the first of my posts (Assuming you missed that) you would see the bracket I fabricated from sheet metal.
The radio is mounted to the angle aluminum with two screws into the radio body using the radio body's mounting holes. It has been there for about 7 years now.
Of course I used lock washers between the angle mounting bolts and nuts.
