Abstract:
A radio frequency signal and power distribution duct system includes mating interconnections permitting daisy chaining of a plurality of individual units to provide as many power and radio frequency signal outlets as desired. Three types of units, types A, B, and C are contemplated. Type A units receive power and signal from external sources. Type B units receive power and signal from type A units, and permit daisy chaining additional type B or type C units. Type C units connect to type A or type B units but do not provide for further daisy chaining. External connection of radio frequency signals in type A and type B units is performed through internal one-eighth wavelength coaxial cables, whereby, when a type A and a type B unit are connected together, the total length of connecting coaxial cable is one-quarter wavelength. An external termination may be connected to a type A or type B unit at the end of a daisy chain. An internal termination is connected to the last coaxial Tee in a type C unit.
