ANTENNA SELECTION ADVNTAGES

For COMSEC, it is always the best policy to use the lowest power setting that still allows reliable communication.

If our equipment is low power then we can use a high-gain directional, or omnidirectional antenna to compensate. And using a better antenna to listen to weak signals increases our effectiveness.
