Size, shape, and elements are key factors in understanding an antenna's capabilities. When examining an antenna, it is essential to consider these aspects to evaluate its potential performance.
Knowledge of antenna basics can help evaluate any antenna design, even without measurements. The size of an antenna is crucial, but it is most important to ensure it is the correct size for the TV-frequency band.
Measurements are great, but an understanding of how antenna elements work will help to evaluate designs just by looking at them!
This understanding can help identify exaggerated claims, such as antennas claiming over 100-mile reception.
