Tonight I did a quick project to mount my Sirius portable satellite radio.
I used the vehicle mounting kit. It comes with an adhesive tape base mount. I cut the base off exposing the threads on the swivel ball. I then found a suitable location close to a power source, out of most of the elements, but still at the driver's control.
I bent a piece of aluminum to get the desired mounting angle and cut it to length.
I drilled the plate and tapped (1/4-20) for the base plate mounting screw. Coated with primer and silver hammered finish spray paint.
Here is a picture of the bracket and base plate assembled. I also cut and drilled a backing plate.
I used the bracket as a template to drill the holes into sideboard. I also picked this area so that there wouldn't be any plain view witness marks if I ever remove the bracket. Here is the bracket assembled. I used nylon locking nuts to prevent loosening.
Here are a few pics of the unit installed.
All that's left to do is mount the antenna. Unfortunately, that'll come after I order a new one since this one flaked out on me.
Simple project that should only take 1-2hrs after you have all the stuff.
