Hi @fallingrock. There is not an extension available for the antenna on the Mailbox Sensor. You are correct, making the antenna face the direction of the Ring Bridge will give you optimal signal. If possible, I would try to remount your Mailbox Sensor.
I understand if Ring doesn’t sell an extension cable, but what is the technical designation of the cable? Maybe I can get something at a local hardware store or electronics store?
I need an extension for the external antenna. Why hasn’t ring replied to this? The whole purpose of the external sensor is to properly mount the antenna towards the bridge. You can’t have more than one bridge so only option is to properly mount antenna. So ring needs to do right by customer and give more length for external mailbox sensor and provide the abilitly for more than one bridge as I have an acre of property and weak signals because of such. Let’s go Ring! This is a pretty easy problem to solve
