2.4 In-building Antennas
The in-building antennas are connected to the coaxial cable distribution system by jumper cables
at various points. The antennas will be mounted on the ceiling tiles and should be exposed. All
in-building antenna installations will be such that it will not interfere with indoor traffic and will
not enable any person to touch the antennas.
