At 300 I write it off. You're definitely into something you don't find in consumer products.
I Have a Simple Google Chromebox that i stream music with and use a computer speaker desktop setup with extension wires to other rooms and a outside porch. What i want to do is broadcast to remote areas of my property from 100 feet up to 2000 feet away to either/and speaker receivers and a headset/antenna receiver so i can listen to music in my greenhouses and while i'm operating a tractor etc. What do i need that i can hook to my google chromebox? I've seen short distance fm transmitters that rebroadcast from a live stream source but don't want to interfere with my neighbors etc. can i use WI/FI or something else? Thanks
