Dual frequency omnidirectional indoor ceiling aerial

The utility model discloses a dual frequency omnidirectional indoor ceiling aerial, characterized in that it comprises a low-frequency reflexion bottom panel (10) on which a low-frequency hypocone (4) is connected. The low-frequency hypocone (4) is connected with a low-frequency epicone (3) through a low-frequency connection strap (7). The low-frequency epicone (3) which is smaller than the low-frequency hypocone (4) is connected with a R deflector plate (2) and the inner conductor of a low frequency cable (11). The low-frequency hypocone (4) is connected with the outer conductor of the low frequency cable (11). The low-frequency reflexion bottom panel (10) is connected with a high-frequency reflexion bottom panel (15) through a bracing column (9). The high-frequency reflexion bottom panel (15) is connected with a high-frequency epicone (5) through a high frequency connecting piece (6). The high-frequency epicone (5) is connected with the inner conductor of a high-frequency cable (12) whose outer conductor is connected with the high-frequency reflexion bottom panel (15). The low frequency cable (11) and the high-frequency cable (12) are both connected with a cable joint (14). The utility model has the advantages of small in dimension, light in weight, convenient installation, reduction of interference among signals and enhancement of the communication service quality.
