I didn't know you couldn't downvote the person one replies to. Thank you for pointing this out, so I retract the suggestion for you to remove the downvote. That is correct, my suggestion requires one to buy a coaxial cable of suitable characteristic impedance at the required frequency, and some u.FL connector(s), they are obviously not included in the doorbell. Drilling a hole in a plastic casing, and installing a connector on bare coaxial wire is pretty simple, one just looks up the steps and performs them. I consider it much easier than PCB board rework (which isn't necessary in my suggestion: just disconnect the u.FL-connected PCB antenna, and attach the coaxial cable). I finally see what you mean: my comment was indeed supposed to reply to the parent T3OU-736 commenter. I switched devices, and your comment made the relevant quote more prominent as opposed to some part in the middle of a sentence... My apologies!

Yes, I understand how to plug something in to a u.FL connector. That was my point: I can kinda tack anything onto anything else dead-bug style, but it isn't "included". The point of a Ring doorbell is to get something that just works-- not to string lots of high frequency coax, dedicate a wifi radio on the other side, figure out appropriate attenuation (probably want about 65dB total between coax and pad from 20dBm to -45dBm), and troubleshoot inevitable resulting fuckery. If you'd come at things from another angle--- replying to the post above, and say-- well, you actually could just patch right into the wifi radio and run coax!-- your comment might have been favorably received.

  One wouldn't need special high frequency coax. Bog standard RG-58/U for example has about 1dB loss per meter (or yard). The loss in the cable means less attenuation will be needed. Quite possibly most WiFi radios can reach low transmit and high receive levels, as some devices are placed in proximity and some at large distance. A top brand 20 dB attenuator can be had for less than $4...

It's also not too close to 50 ohms up that high above design frequency and the connectors make huge reflections. > Quite possibly most WiFi radios can reach low transmit and high receive levels, as some devices are placed in proximity and some at large distance. Path loss of even adjacent antennas is pretty high. Again, though, this is all a huge diversion: all I did was point out that Ring does actually offer PoE doorbells, and you came in and "corrected" me.

      As I said, you'd have to find out the characteristic impedance at the u.FL connector first, and then select the appropriate coax (obviously at the frequency of interest). BTW does the PoE doorbell you linked actually have an ethernet network, or does it just use it for power? I fully concede my original comment should have replied your parent, but the following replies were responses to the contents of your comments (Frankenstein, etc.)

        > BTW does the PoE doorbell you linked actually have an ethernet network, or does it just use it for power? Yes, it uses it for data and power (power is optional: you may power it separately)
