It looks like you have scaled tube diameter Eddie,


I only scaled for length on 50mhz & hoop diameter to get the radials close to the same angle & spacing relative to wavelength,


relative to wavelength I am using a fatter monopole & radials than any of the 27mhz versions,


bottom tubes inside the cone are 37mm od & 33mm od,  5 sections in total,

radials are 13mm x 1400mm & 10mm x 1300mm,


I can measure the exposed lengths & diameters tomorrow but not the top section until they are tuned.
