We all know about the coach to quarterback helmet comms used in the NFL. This year the NFL leveled the playing field by doing the same for the defense. A selected defensive player will receive coach to defense helmet comms. Here are some of the rules;
- Only one player with a helmet receiver is allowed on the field at a time, one offense (quarterback), one defense (usually a linebacker or safety).
- Receiver equipped helmets are marked with a green dot on the back of the helmet so officials can easily identify the designated player.
- The helmet comms are disabled when 15 seconds is reached on the play clock.
It is my understanding that these comms are encrypted. What frequencies are used?
The first NFL link, below, is the best info. The USA today article is also good, if there is an accuracy issue, please consider the source (non-radio personnel don't always translate the technical aspects properly);
