Troubleshooting Rule of thumb: Wavelength at 1 GHz = 1 foot
(3 * 108 meter/second)/(109 cycles/second) = 3 * 10-1 meters = 0.3 meters = 30cm
30 cm / 2.54 cm/inch = 11.81 inches
| Frequency | Wavelength |
| 1 GHz | 1 ft |
| 100 MHz | 10 ft |
| 200 MHz | 5 ft |
| 400 MHz | 2 1/2 ft |
| 10 GHz | 1/10th feet = 1 1/4 inch |
| 18 GHz | 1/20th feeth = 5/8 inch |
