Constant Height Paired Fractals
Two radiators are assembled side by side. One radiator
is a 1st order Koch Triadic, the other is a 2nd order Koch Triadic. The height of these paired antennas is 16 Meters.
Given either form contains more wire than the standard monopole, it stands to reason we will find SWR nulls occurring
at lower frequencies. In a style consistent with the Constant Band Comparison, only the first SWR null will be
analyzed.
This is the 50
Ohm SWR for a standard 16 meter tall radiator. This curve establishes the baseline against which we compare the
pair to. For this height of a monopole above a perfect ground, the first resonance occurs just below 5 MHz.
This is the normalized SWR for
a 1st and 2nd order Koch Triadic radiators with unconnected tops. There is a notable drop in frequency for the
first resonance (which ever of the two nulls you may choose).
This is the normalized
SWR for a 1st and 2nd order Koch Triadic radiators with connected tops. Closing the connection at the top appears
to pull the two nulls together.
This is the 50
Ohm SWR for a 1st and 2nd order Koch Triadic radiator with connected tops and the 1st order side driven (2nd order
goes to ground). This appears to exhibit the qualities of a folded monopole with the increase in drive point Z.
