Match Stub Calculations
On   this   page   is   a   calculator   for   coax   cables   matching   stubs.      Start   by   selecting   the   type   of   coax cable   you   are   using.   Input   your   parameters   in   the    Blue    cells,   then   tab   to   the   next   input   (new values does not take effect until the tab is pushed). The   top   section   is   for   calculating   a   ¼   wavelength   matching   stub   for   matching   impedance.      Input you antenna impedance and it will calculate the needed impedance of the matching stub. The   second   section   will   calculate   the   length   of   the   matching   stud   for   the   selected   coax   and frequency.  (Notice when you select the coax it will indicate the impedance.)
