Call box for gate/remote entry

It would be great if Ring could produce a call box that could be mounted with a Liftmaster keypad outside a gate. I have seen several people online who have created their own (and while functional, none of them have that "professionally finished" look". My understanding is that you can't really use a commercial one because they are made of metal and will interfere with the Wi-Fi connection. Even a nicely finished plastic housing that had the doorbell built-in and a place to mount the gate keypad (with a hole in the back to run the wiring through) would be better than what we are working with now.
