"Of course you can show your academic ability in telling the group WHY it "cannot possibly work" or wait for another expert to state "why" to save face." No one is saving face or conspiring against a new idea. You can`t break the laws of physics no matter how hard you try. Antenna performance is based on lengths of wire in the air and the currents in them. Take a broadside array for example. It is usual to drive current through all the elements of a plane in the same phase so that the fields at a distant point perpendicular to the plane of the array are additive to make a large signal. It is a matter of radiator lengths and currents. Now consider a small diameter coil as a radiator. It is called an radial mode helix because radiation is radial (perpendicular to the axis of the coil). It has two extremes. If collapsed, the coil becomes a single loop. If stretched to its maximum, the coil becomes a straight wire. If controlled so that the same magnitude and direction of current flows in all configurations, the straight-wire version of this coil should produce the greatest radiated field strength perpendicular to the coil axis in the far field.
