wrote: The experimental antennas are as small as one- fiftieth of a wavelength and could shrink further. In fact, commercial Ham antennas with similar efficiencies at similar scales have been around for decades. Shrinking them further encounters loss accumulating at the 4th power of size. This is a very difficult proposition to beat in stale reporting with the concurrent lack of proven models following after lo' these 4 years. That is pretty sound evidence of these researchers having been lost beyond the precipice of an astronomical plunge in efficiency. 73's Richard Clark, KB7QHC |
