We don't have the section lengths Eddie,

you could work the diameters out using wall thickness but they use unequal lengths as seen in the video & the mk2 version 2 uses longer 38.1 & 30mm tubes,

I won't be doing any tuning for signal strength, I will tune for a low vswr,

Vortex claim 4.41dbi @8degrees for the mk1 & 5.82dbi @7.5 degrees for the mk2,

they used 10mtrs above average to good ground on 27mhz & you use about 1 wavelength above ground in models, I will test at about 1 wavelength above ground on 50mhz.
