"Art Unwin" wrote in message ... This week end is going to be wet and cold, so I thought I would give you a radiator to play with if you are willing to make something for yourself. Get yourself a piece of aluminum mesh used for window insect stopping entering your house. Soak this piece of mesh in some watered down muriatic acid (approx $5 a bottle at a hardware store This is to remove the insulating coating so it becomes conductive. Now this mesh is woven so it helps to compress the strands together by tapping with a hammer. Connect a MFJ259B to the base corners and scan to see where the resonant frequency is. I used a 8" x5" piece of mesh and it was resonant from about 110 to 140 MHZ so it is quite broad banded and easy to find the resonance The vertical strands carry the applied current and the capacitance square holes in between is a electrostatic field around which the displacement current flows. What you have, basically, is a full wave dipole folded very closely upon itself to form a closed circuit with a low impedance. This is basically a transmission line if the ends are open. The cross jumpers take the place of dielectric spacers that are present on a open transmission line so that they may enclose an electrostatic field created by the displacement current. The vertical strands are really in series ,so you have effectively placed a long length of wire into a small volume which you may shape into any form. To play with this further, place it above a conductive sheet and note the changes. Then try pinning it together into a cylinder and note the changes. Have fun playing with it. Looking at the physics side of things. When a particle is generated by the Sun it goes to the border and even tho it is extremely small it breaks the border by applying a straight force vector together with a circular vector. This same combination repeats itself when current is applied to a radiator which also produces a circular current. These same vectors are later repeated with gravity in combination with rotation all of which are per laws of Newton. The particles that escape from the sun sheath conductive materials on Earth. This is explained by making the Gaussian field for statics a dynamic one so that it becomes the same as Maxwells laws. The combination of fields from the applied current when intersecting the electrostatic field dislodges particles by elevation with spin while accellerating to the maximum speed which is that of light so the particle can take on a straight line trajectory with spin where the Gravity vector is cancelled. Elermentry explanation of the weak force in the Standard model (Patents applied for) Art Since you're lecturing on physics, as I said before, you should post this to sci.physics and sci.physics.research and see what they think. Chris What I'd like to know is how the vertical and horizontal strands know which role they are supposed to play? And if I rotate the mesh by 90 degrees but still keep the feed the same, why don't those roles change? What if the whole thing is parallel to the ground? It should stop working completely. Hell, it could even explode for all we know. The poor strands wouldn't know what to do and the energy would build up until there was too much and - BOOOOOM!!! And what happens if this antenna is in space? Does it stop working? Do the bits remember what orientation they used to be in when they were on earth? Or is this all just some fantasy dreamed up by someone who needs serious medication? Most likely the latter. tom K0TAR |
