1. The cover helps me to sleep with the plasma running. I keep the phanotron within just a couple of inches from the area that needs work. Some people have made swings from which the phanotron hangs. If you search this group under phanotron you can see photo's that people have uploaded.
2. We recommend you can stay within the near-field of the tube. That is the field type used by doctors when they used the original Rife machines. They found that beyond several feet the results were not so good. The signals can still be detected but the field starts turning into far field. Plasma produces two related fields. The one that does the really heavy lifting is the near-field, and this extends six inches from the tube in all directions. After six inches, it becomes far-field, which isn't as effective as near-field, although it still works efficiently enough to disinfect and clear mold from a home. So it still works on the body, just not to the same extent and power as near-field.
