To maintain the desired frequency the sum of Vertical + Radial length increases substantially (Red line). To adjust to the lowest SWR the Vertical/Length Ratio (Blue line) will be near 0.5. ie Radials are lengthened to approach the same length as the Vertical. Figure 2 Tuning Webground radials are required for a "perfect" ground. 120-radials were never established as a minimal "perfect ground". 120 radials are not even an "FCC mandated ground". Still, practical radial systems can be large. radial systems require more wire than proper elevated systems for the same single-bandRF performance. Note collect tinfoil
