At 20 meters, the overall length would be about 65 feet, and the two halves
of the dipole would be about 32 feet. Perhaps one of the Hams here can help
you out with the coil specifications.

The dipole would need to be (10 metres * velocity factor of material)
long to be resonant on 20m band, roughly 16'6" per leg.
