The VHF-FM direction finder (homer) allows you to zero in on what aspect of FM signal?

• A. Direction
• B. Distance
• C. Frequency
• D. Power

Answer: (A)

The VHF-FM direction finder, or homer, is used to determine the bearing to the transmitting station. It doesn’t measure distance, frequency, or power. The device uses a directional antenna to detect the signal and you rotate it until you find a null (or a peak) in the received signal, which gives you the bearing toward the transmitter. With that line of bearing, you can plot on a chart or steer to locate the source. Estimating distance would require additional methods (like triangulation with another bearing) and the unit itself doesn’t reveal the transmitter’s frequency or power.
