1. The module holds no power source beyond its own radio, so the coaxial run wastes the sent bytes and the passive antenna shapes the radiated beam in that implementation.
2. The module holds no power source beyond its own radio, so the coaxial run wastes the sent energy and the passive antenna shapes the radiated wattage in that implementation.
