Isofrecuencia broadcast a series of antennas that emit the same program orthogonally polarized between two consecutive antennas.

摘要

PROCESS AND DEVICE FOR BROADCASTING isofrecuencia FOR RECEIPT ON BOARD A VEHICLE OF SAME PROGRAM THROUGHOUT THE JOURNEY JOURNEY IN WHICH HAS, IN THE VICINITY OF THE JOURNEY OF THE ISSUERS provided with at least one antenna EMISSION (EN2, EN-1, EN), wherein the transmission antenna (EN2, EN-1, EN) is tilted 45 (EN-1, EN; EN-11) NEAR ISSUER EQUALLY INCLINADA 45 But in the other direction. The polarization of the field emitted thus forms an angle of 45 AS TWO antennas ISSUERS NEIGHBORS form between them an angle of 90.
