[sci.electronics] Radio link from intrusion alarm? Vi

jim@trsvax.UUCP (01/07/89)

How are the commercial auto alarms able to get the advertised 8 miles of
range? (unless that's 8 sqaure miles 8{)  If it is just a type-accepted
transmitter used on a specific band, does anyone know of a company that 
sells just the modules? From the size of one or two of the remote control
units i've seen on keychains, they must be using UHF. Thanks!
