Re: Diamond weave coil anteena, first reports-FARMERIK
I am not sure what word is best, but like a radial aircraft engine, the cylinders go out from the center, or spokes on a wheel. So it is more like the pattern of a ferrite loop, off the 'sides' of the windings, but these Diamond Weave coil antennas do not seem sharply directional. Both the signal strength AND more importantly the signal to noise ratios are boosted together compared to the stock PL-360 tiny ferrite.toggle quoted messageShow quoted text
Because I thought the larger center opening would bring more signal strength, that is what I asked for when these were made. That may not be true at all. I am curious if the compact coils have the same pick up pattern. Mine are quite narrow, in order to allow the largest diameter. I guess the area as viewed from the side would not change too much, but that is just a guess.
When tuned by a cap, and inductively coupled to a radio, some have a large boost at a certain point along the radio, and others do not. I suspect that has some thing to do with how the radios internal ferrite antenna is wound.
