What brand and model of mag mount antenna are you using? It's tiny, just what my xyl wants. I just bought an IC7100 so now Im getting serious about installing it in the model 3. How did you route the 12 V power and control cables to the trunk?Here is how to mount your antenna and route the coax to prevent water in the trunk.
Keep it down in the trough and don't cross the second seal until the bottom of the trunk.
