Chosen Solution

I am trying to improve WiFi signal reception with an alternate mounting location. Any information on location/orientation of antenna would be helpful.

Sadly you really can’t alter the Ring unit, but there is a way to solve this! You’ll need another WiFi AP near the door inside. A WiFi extender unit or a Mesh WiFi Router setup which can also extend your signal area into other parts of your home.

Late reply, but hopefully this helps. FCC filings are a great resource for wireless device information. Here’s a link to the Ring Doorbell 2 filings: https://fccid.io/2AEUPBHARG041 Under the “Internal Photos” exhibit you’ll find photos of all the doorbell’s components. Under the “Test Report” exhibit you can find information about what antenna the device uses. The Ring Doorbell 2 uses a 2.4Ghz PIFA antenna made by Inpaq.

Adding an external antenna to this model looks fairly straight forward. The stock antenna uses a U.FL connection that makes it very easy to replace. You could try removing the stock antenna and replacing it with something like this: https://www.amazon.com/Oiyagai-2-4ghz-An
