Tom, W8ji apparently is an expert with antennas having lectured at Dayton and has authored many technical articles around antennas, states that radiators must be straight for maximum efficiency, I highly doubt he ever said anything of the sort. apparently a break off from the standard ham statements of bigger is better as well as more wire is better. And the physical reality that antenna performance is directly related to size in wavelengths. snip rest -- Jim Pennino Remove .spam.sux to reply. |

As long as you turn a blind eye to what he states then you are in good shape! But then somebody in this group will point you to Tom's statement and you can then respond as to what he really meant which is not what he stated. apparently a break off from the standard ham statements of bigger is better as well as more wire is better. And the physical reality that antenna performance is directly related to size in wavelengths. It depends on your definition of "size". I prefer the term encapsulating volume. All physics laws are based on the presence of equilibrium. Thus you may deform a radiator to the smallest volume as long as you retain a state of equilibrium, regardless of the number of wavelengths at issue. This is why "point radiation" is still discussed. As an aside, the number of wavelengths used has nothing to do with Maxwells equations which accounts for ALL forces presence in the forming of radiation and not the simple radiator coupling and re radiation approach alone. It all comes down to root L.C. in a equilibrium environment as the determinate factor in his equations. So, the bottom line is that you disagree with the statement made by Tom as being incorrect. It will be interesting what the rest of the group have to say as they wade in. snip rest -- Jim Pennino Remove .spam.sux to reply. |

I highly doubt that will ever happen either. apparently a break off from the standard ham statements of bigger is better as well as more wire is better.

Yeah, sure. snip rest -- Jim Pennino Remove .spam.sux to reply. |
