[QUOTE="Henry Cohen, post: 33397, member: 123"] Re: Wireless Feed to Nursery? Odds are a low power RF transmission, even in the low VHF band, will not propagate through the numerous concrete (with rebar no doubt) walls. The most obvious test would be to take their current ALS system and see how far that gets you. You should re-orient the transmitter or antenna to a more optimum location for the test. If you get less than 80% of the way, there's no cost effective license-free RF solution. As to other options, is there any copper that's common to the two locations; telephone wires, networking, coaxial TV? Almost any type of wiring can be used for analog signal transport with appropriate baluns or active interfaces. There's also audio over power line interfaces so long as the route from point A to B is on the same phase/leg (and not going through any transformers). [/QUOTE]
