Extra exam question E9C06

WhyAdding a terminating resistor to a rhombic or long-wire antenna changes its radiation pattern from bidirectional to unidirectional. Adding a terminating resistor to a rhombic or long-wire antenna absorbs the traveling wave that would otherwise reflect back and create a standing wave, converting the antenna's radiation pattern from bidirectional to unidirectional, pointed toward the far end where the resistor is located, answer B. It doesn't reflect standing waves back to the transmitter (it absorbs energy that would otherwise cause that reflection), doesn't change polarization from horizontal to vertical, and doesn't reduce ground loss, that's unrelated to what the terminating resistor does.
