In thi s paper analys is of two rad iation problems whic h have practical application to improve radio co mmuni catio ns durin g re•entry blackout period is prese nted.In both of these exa mples given here, th e mutual orientation of the ante nn a and an external stati c magnetic field is chosen in s uch a way th at the fi eld co mponents are indepe ndent of the co mpone nt of the plasma•dielectric tensor parallel to the static magnetic field.This c hoice e nables one to control more effectively the electromagneti c waves by con trolling th e app lie d d•c magnetic fi eld .T hough the prob le ms invest igat, ed he re in volved cylindri cal body of infinite length, a knowledge of these results will throw more insight into the expected behavior of the radiation field from a uniform magne ti c ri ng c urre nt around a co nical space vehicle covered by a plasma sheath in the prese nce of a un iform azimuthal stati c magnetic fi eld,
