A wireless communication system for closed environments including a plurality of antennas parallel line coupled to the coaxial cable of a coaxial cable radio frequency transmission system. Each antenna includes a quarter wavelength long conductor positioned between the center and outer conductors of the coaxial cable. The conductor is axially aligned to the cable and insulated from the center and outer conductors by the cable's dielectric core. The conductor is connected to a quarter wavelength radiator supported by a conductive bar clamped to the exterior of the coaxial cable.
