Got my antenna mounted for my quadband radio. I pretty much stole this idea from "ncalphadog" on here.... :whaa:
But it works really well!
Here are the steps I took during the process:
- Locate rear outer trim piece, as you'll be mounting the bracket to the body that is hidden by this piece
- Lower pop clip
- Upper pop clip
- Piece removed
- Make a cardboard template, making sure to allow for room around the outer pop clip, and also allowing room for the inners that were shown above
- Make the second piece of your template
- Transfer hole locations onto the body
- Transfer your cardboard templates into a CAD program, and print to scale to check for accuracy. Make any desired changes at that time.
- Fire up the CNC Plasma Table and cut your parts out of 3/16" steel. Or source your files out to a local fab/laser shop.
- Drill your hole locations into the body, being careful to select the right drill bit for your threaded inserts. You could also use some self-tapping screws I'm sure. I chose to TIG my inserts onto the body, so that required grinding down a small area around each hole. MAKE SURE you pay attention to which holes you'll actually be welding to, and DON'T do like I did and grind around the pop clip hole. LOL it's just not necessary!
- You can see how the threaded inserts fit into the new holes
- Then you'll need to grind off the yellow zinc coating, so that it doesn't contaminate the welds. TIG is very picky about that kind of stuff, and I didn't get it all off apparently, so my welds ended up looking like crap. Oh well, they're solid at least...
- Using 1/16" tungsten and a #6 cup for the light gauge stuff. Then switching back to my 3/32" tungsten and gas lens for welding the 3/16" plate together.
- Rear shackle works as a torch holder.
- First set of tack welds and a little grinding. Gotta be really careful with the head on those threaded inserts.... It's like 20ga and tries to melt away on you. Found it best to make a few tacks around it, then lightly grind down and then go over the spots I missed. When you're done, it will blend right into the body panel. No pic of that though....
- Test fit the panel
- Position your tab, and tack it into place. Once that's done, you can set the antenna on top, and level the tab out.
