Title: Improvements relating to communications systems
Inventor: SMITH COLIN LESLIE
IPC: H04B5/00
Filed: 1983-06-29
Abstract: On a building site a worker 11 is able to communicate with the crane operator in a cab 2 by passing signals between a transmitter/receiver unit 10 and a leaky feeder cable 8 interconnected with a main radio transmitter/receiver 7 via an impedance matching circuit 9 which enables the operating radio frequency energy of the unit 7 to be tuned to the length of the cable 8 so that leakage of signals occurs over the whole length of the cable. By this means signal transmission is largely confined to the area swept by the jib 3 carrying the cable 8. As an alternative a section of leaky feeder cable 13 could be attached part way up the tower of the crane 1 so that signal transmission is confined by the walls 5 of the building being constructed. Cable 13 is connected by an impedance matching circuit 14 to a transmitter/ receiver unit 12 connected to an intercom unit 7. <IMAGE>
