Can Anyone Suggest A Vibration Reducing Flat Wall Mount?

I have the WeatherFlow in the box to install on a side of an apartment building. Reading the vibration problems, I figure that mounting it to a wall with a flat mount and 5ft steel pole. I’ve been looking online and only see the “Y” shaped wall mounts.

Is there anyone out there that has a suggestion of a wall mount that is possibly a plate and maybe put neoprene when attaching it to the wall to reduce this vibration issue?
