If the Logitech BT receiver becomes a problem, check out Miccus- I used one for a school gym and when I walked the floor and 15' border of the full basketball court, it never dropped out, even though the signal has to go through two concrete block walls. It wasn't much more than the Logitech.
My mechanic told me, "I couldn't repair your brakes, so I made your horn louder."
