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. Best regards, Richard Harrison, KB5WZI I don't know where you get this straight busines from. the wire will radiate no matter what shape as long as it is in equilibrium which means straight or otherwise. No law says it must be straight or else unless you can show it to me. The helix is not straight! Making a helix a full wave circuit gets rid of the counterpoise, it does not stop radiation. Kraus suggests that a helix can supply a 16 db gain which is very high but tnever the less gain can be achieved. So I do not see the point that you are silently dwelling aponto justufy that it can,t work as well as radiators MUSt be at right angles to the earths surface for maximum vertical gain. You have never explained the u nderpinnings of your statements in academic form without which there is nothing I can debate with you |
