Folded dipole 420-450Mhz
Frequency response of my folded dipole build for 420-450Mhz, the cutting frequency is around 436 Mhz originally - the resulting configuration for a 4 stacked collinear dipole array is usable from 420 to 450Mhz with repeating frequency response with center of around 438Mhz at 1:1 VSWR the, VSWR response across the frequency band is less than 1.6:1 from 420 to 450Mhz
