- Condensers having maximum capacities from 0.0005 to 0.003 microfarad may be expected to have a minimum capacity of about 0.00005 microfarad.
From the table, with a condenser of maxi- mum capacity of 0.001 microfarad, and three turns on the 4-foot coil, the wave-length range will be from 130 to 400 meters.
