The Mini Loop Antenna on WMEC/WHEC is directional in which way?

• A. Bi-directional
• B. Uni-directional
• C. Omni-directional
• D. Directional

Answer: (A)

A small loop antenna has a pattern with two opposite directions of strongest reception, forming a bidirectional pattern. The Mini Loop on WMEC/WHEC is most sensitive in two directions that are 180 degrees apart within the loop’s plane, with nulls perpendicular to that plane. That’s why the best description is bi-directional. It isn’t omni-directional because it isn’t uniform from all directions, and it isn’t uni-directional because there are two opposite strong directions rather than a single one. When you rotate the loop, you’ll observe strong reception in two opposite bearings and weaker signals from other directions, which is the telltale sign of a bidirectional loop.
