Why does the mount for the Ameri-King ELT have a "wedge" under the rearward end so that the radio is tilted 20 up in the back?

It doesn't. Loosen the strap and slide the unit forward until it sits flat,
then re-fasten the strap.

I should have included pictures the first time. This is the Ameri-King 451 406 ELT and the very first ELT that I have ever dealt with. There is a lip around the tray that completely surrounds the radio. The only way to move it forward would be to have the radio sit on the forward lip. See the attached pictures.

It's likely the mounting angle has something to do with impact activation during a crash, where most of the energy will be in the longitudinal direction, but some will be vertical. In helicopters, this angle will be greater since they tend to impact at a steeper angle.

The g-switch is likely mounted axial with the box. I presume the instructions call for one end (the one opposite the 'bump') to be mounted forward. Is this the case?

Yes - there is an arrow labeled "Forward" opposite the bump and it matches a similar arrow on the radio that can only be installed one way. I will contact Ameri-King next week to confirm but your analysis seems correct.
