Subject: more on loops and quad loop formulas
for general interest:
the formulas for building a directional antenna using loops, or what we
typically refer to as the quad antenna is as follows:
for the reflecter: 1030 divided by frequency
driven element: 1005 divided by frequency
first director: 975 divided by frequency
I believe all additional directors are calculated by reducing the length by
5 percent.
