Just to be sure - and I only say this because it can be easily missed - this isn't a range extender that sends the wifi signal over the air, this puts the signal on your physical electrical wires in the ground that are carrying the power out to your coop. Now, that being said, you are a good distance with the couple of acres, and this technology will be affected by other outlets that might be on that same circuit etc. In my case, completely by luck, I have a single circuit in the garage where I put the signal on, and then another single circuit in the shop where I take it off the power wire. That probably gives me the maximum strength possible. Anyway, don't mean to imply at all that you weren't following the technology, just purely making sure that you knew I was referring to something that used physical power wires between two points, and not a basic range extender that would go over the air. Regardless of the technology, I can see how you have a challenge with that great of a distance. You're definitely dealing with a non-trivial setup there. Unfortunately, it might take specialized tech that costs much more than the $35 Wyze camera that gets hooked up!
