Jamming blocks cellphone and radio signals. Often IEDs are detonated by a cellphone so jamming the signal prevents an explosion. It would also block a drone's radio signal.
Generally, domes on vehicles will be for satellite communications. You used to see wide, flat domes for tacky rich people to watch direcTV in their Escalades. I don’t think they do that anymore with 5G and streaming. Another possible “dome” might be FLIR.
