For safety, how high should you place a horizontal wire antenna?
A
Answer
Basic radio theory
Type
A
High enough so that no one can touch any part of it from the ground
B
As close to the ground as possible
C
Above high-voltage electrical lines
D
Just high enough so you can easily reach it for adjustments or repairs
Answer Notes
Transmitting antennas carry high levels of radio frequency (RF) voltage. If a person touches a transmitting antenna, they can suffer severe RF burns or dangerous electrical shocks. To prevent this, horizontal wire antennas must be strung high enough so that no one can accidentally touch any part of them from the ground.
Placing an antenna so it is easily reachable for maintenance creates a massive, immediate safety hazard for anyone walking nearby. The antenna must always be out of casual reach to protect bystanders and family members.
Another highly dangerous distractor suggests placing the antenna above high-voltage electrical lines. You should never place an antenna above or near power lines, as a break in the wire could cause your antenna to fall directly onto deadly high-voltage lines, potentially electrifying your entire radio station.
