I am trying to figure that out and thought about that, not tech savvy, do you have any info about that?

Not sure how it worked. Perhaps a beacon good to 500 meters. Another alternative would be a small FM transmitter. I’m pretty sure they’re good up to a quarter mile.

One update before buying anything - the pastor put himself on Facebook live. Folks in the cars got it on their phones and bluetooth delivered it to the car speakers. He also had loudspeakers outside for those up front who may not have had a smartphone. Rain? No idea. Pretty nifty.
