Descriptive summary

As discussed here https://github.com/usdot-fhwa-stol/carma-platform/issues/993, DSRC messages on the truck are currently only being broadcast by one antenna, which can allow the signal to be obscured by the truck trailer. To get around the physics of this problem, it would make sense to broadcast the same message from multiple antennas, however, if this is done carma may need to be updated to properly filter such incoming information so it is not processed twice.

Carma version where this issue was discovered
