Digital Audio Broadcast Antenna And Module
| Refer to COMPONENT INDEX . |
Digital audio broadcast antenna is a digital radio standard for broadcasting digital audio radio services, used in many countries around the world, though not in North American countries. The antenna for digital audio broadcast signals is screened on the windshield and connects to the digital audio broadcast antenna module, which amplifies the digital audio broadcast antenna signals for the radio.
A digital audio broadcast antenna module and antenna are used in the countries that use it in place of an AM/FM antenna to receive digital audio broadcast signals.
The digital audio broadcast antenna module is powered by a 9 volt output from the radio through the coaxial cable whenever the radio receiver is active. The module receives digital audio broadcast Radio Frequency (RF) signals supplied by the on-glass digital audio broadcast antenna grid elements screened to the inside of the windshield glass. The capacitor selectively filters Radio Frequency Interference (RFI) from the received signals, while the module amplifies the received signals. The filtered and amplified signal is then sent through the coaxial cable to the radio digital audio broadcast antenna input.
The hardwired inputs and outputs to the antenna module may be diagnosed using conventional diagnostic tools and procedures. However, the module is diagnosed by substituting a known good external antenna to compare reception performance.
