What is the effect of adding a terminating resistor to a rhombic or long-wire antenna?
Pick an answer to check it.
Answer: B. It changes the radiation pattern from bidirectional to unidirectional
A terminating resistor absorbs the wave that would otherwise reflect from the far end. This removes the rear lobe and makes the pattern unidirectional.
Tip: Terminate it to make it one-way.
