Very nice install. Rare to see the attention to detail that you have put into your installation.
Do you have a picture with the Toughbook mounted? Curious to see how that looks in there. Also, does the 19" whip on the back move in the wind much when driving? Enough to hear it at all anyway.
I have a small VHF whip on my right rear trunk and heard it whistling one day. Then realized that ice had formed on it and was causing the whistling noise. Broke the ice off and all was quiet again.
Once again, great install, and attention to detail.
