For best RF safety, where should the ends and centre of a dipole antenna be located?
B
Answer
Basic radio theory
Type
A
Close to the ground so simple adjustments can be easily made without climbing a ladder
B
As high as possible to prevent people from coming in contact with the antenna
C
Near or over moist ground so RF energy will be radiated away from the ground
D
As close to the transmitter as possible so RF energy will be concentrated near the transmitter
Answer Notes
A transmitting dipole antenna can carry dangerously high RF voltages, particularly at the far ends where voltage nodes form. If someone accidentally touches or brushes against any part of the antenna while you are transmitting, they can suffer a severe and painful RF burn.
To ensure maximum safety, both the center and the ends of a dipole must be mounted as high as possible, well out of physical reach of people and pets. Placing the antenna close to the ground for easy adjustment creates a highly dangerous environment that violates basic RF safety practices.
